Hardware Requirements

For an explanation of architecture names, see Code Builds

Processor Requirements

• For general operations with user interface and all data collection except Hardware event-based sampling analysis:

  • A PC based on an IA-32 or Intel® 64 architecture processor supporting the Intel® Streaming SIMD Extensions 2 (Intel® SSE2) instructions (Intel® Pentium® 4 processor or later, or compatible non-Intel processor).

  • For the best experience, a multi-core or multi-processor system is recommended.

  • Because the VTune Amplifier requires specific knowledge of assembly-level instructions, its analysis may not operate correctly if a program contains non-Intel instructions. In this case, run the analysis with a target executable that contains only Intel® instructions. After you finish using the VTune Amplifier, you can use the assembler code or optimizing compiler options that provide the non-Intel instructions.

• For Hardware event-based sampling analysis (EBS):

  • EBS analysis makes use of the on-chip Performance Monitoring Unit (PMU) and requires a genuine Intel® processor for collection. EBS analysis is supported on Intel® Pentium® M, Intel® Core™ microarchitecture and newer processors (for more precise details, see the list below).

  • EBS analysis is not supported on the Intel® Pentium 4 processor family (Intel® NetBurst® MicroArchitecture) and non-Intel processors. However, the results collected with EBS can be analyzed using any system meeting the less restrictive general operation requirements.

  • EBS analysis within a virtual machine is available in the following environments virtualizing the on-chip Performance Monitoring Unit (PMU):

    • VMware Fusion* 5 and higher

    • KVM with Linux Kernel 3.2 and QEMU 1.4

    • XEN 4.0 and higher for User Domain (domU)

  Event-Based Sampling and Sampling with stacks data collection is functional inside a virtual machine only for architectural events.

  Please see the Performance Monitoring Unit Sharing Guide for more details on the supported architectural events.

  VTune Amplifier installation detects virtual environment and disable sampling drivers installation to avoid system instability.

  Hardware Event-based Sampling (EBS) analysis runs a driverless sampling collection via Linux Perf* tool.

• The list of supported processors is constantly being extended. In general VTune Amplifier supports publicly launched Desktop, Mobile, Server and Embedded Processors listed at Product Specifications. For pre-release processor support please file a support request at Online Service Center (Online Service Center).

Issues and Limitations

Common Limitations

Running time is attributed to the next instruction (200108041)

To collect the data about time-consuming running regions of the target, the Intel® VTune™ Amplifier interrupts executing target threads and attributes the time to the context IP address.

Due to the collection mechanism, the captured IP address points to an instruction AFTER the one that is actually consuming most of the time. This leads to the running time being attributed to the next instruction (or, rarely to one of the subsequent instructions) in the Assembly view. In rare cases, this can also lead to wrong attribution of running time in the source - the time may be erroneously attributed to the source line AFTER the actual hot line.

In case the inline mode is ON and the program has small functions inlined at the hotspots, this can cause the running time to be attributed to a wrong function since the next instruction can belong to a different function in tightly inlined code.

Collection missing data for core_0 on Skylake-X systems (VASP-11480)

On some Skylake-X systems with enabled SMT mode, VTune Amplifier hardware sampling analysis might collect data against less logical CPUs than available on the system. As example, the problem was reproduced on Intel(R) Core i9-7900X 10C20T CPU installed on an Asus® PRIME X299-DELUXE motherboard.

Workaround: Upgrade the BIOS and the firmware of the board to version 0802 or later.

An application that allocates massive chunks of memory may fail to work under VTune Amplifier (200083850)

If a 32-bit application allocates massive chunks of memory (close to 2 GB) in the heap, it may fail to launch under the VTune Amplifier while running fine on its own. This happens because the VTune Amplifier requires additional memory when profiling an application. The workaround could be in using larger address space (for example, converting the project to 64-bit).

Hardware event-based analysis may crash certain Intel® Core™ i7 processor-based systems when deep sleep states are enabled (200149603)

On some Intel® Core™ i7 processor-based (code named Nehalem) systems with C-states enabled, sampling may cause system hanging due to a known hardware issue. To avoid this, disable the “Cn(ACPI Cn) report to OS” BIOS option before sampling with the VTune Amplifier on Intel Core i7 processor-based systems.

Instruction set reference document is not positioned on description of proper instruction. (200091200)

The reference information for assembly instructions can be opened in any PDF viewer, but only Adobe Acrobat Reader* supports positioning the instruction reference document on the required page. To ensure correct functionality of this feature, you are recommended to install the latest available version of Adobe Acrobat Reader.

VTune Amplifier does not support profiling an application launched under debugger (200092508)

The Basic Hotspots, Concurrency, Lock and Waits, Memory Access with object tracking and Disk I/O analysis types provide incorrect results when analyzing an application launched under a debugger. VTune Amplifier does not detect whether a debugger is attached to a profiled application. Make sure that no debugging tools are attached to the application that is profiled with the VTune Amplifier.

Timeline pane displays incorrect concurrency and thread states for a paused region in the Concurrency and Locks and Waits analyses. (200204715)

Concurrency and thread state data may be incorrect in the Timeline pane for a region corresponding to the time when data collection was paused. Ignore the timeline data in a paused region during result analysis.

Only one stack frame is shown in Java code if IBM* J9* JVM is used (200227950)

Currently Java stack unwinding is not supported for IBM* J9* JVM.

Results not collected for processes terminated with TerminateProcess() (200108689)

No results are displayed for any process being profiled that is terminated by a different process calling TerminateProcess(). Instead, a different method should be used to terminate the process.

Do not use -ipo (Linux)//Qipo (Windows) option with Intel compiler version earlier than 13.0. (200260765)

If using the Intel® compiler version earlier than 13.0, to get performance data on inline functions, use the additional option -inline-debug-info(Linux)//debug:inline-debug-info (Windows), but avoid using the /Qipo option. Currently this option disables generating the inline debug information in the compiler. Note that the Intel compiler integrated into the Microsoft Visual Studio* IDE uses the -ipo//Qipo by default in the Release configuration.

Java source line may be shown incorrectly for Oracle JDK 6u25 x64 (200167001)

Drilling down to Java source code from VTune Amplifier results may show incorrect source line. The issue occurs with Java applications built with Oracle JDK 6u25 x64. This is the JDK problem, refer to issues JDK-7051767 and JDK-7047624 in Oracle bug database.

Result finalization may be slow if results are located in a remote network directory (200169322)

The problem is caused by slow network access. To improve performance use local directory for result storage.

Call stack can’t be unwound via no return functions (200263851)

If analyzed application contains functions without ret instruction (for example, calling exit()), unwinding call stack to its caller and higher may fail (no stack frames shown).

Attaching the VTune Amplifier to a process may take some time (200276420)

Your target application may complete before the data collection starts, so the VTune Amplifier may report an error. Increase the duration of your test application if necessary.

Command line option "amplxe-cl -command status" is currently supported only for user-mode sampling and tracing based analysis types, but not for EBS analysis types.

Hardware event-based analysis may cause unpredictable system behavior on processors based on Intel® microarchitecture code named Sandy Bridge (200285401)

On processors based on Intel microarchitecture code name Sandy Bridge, hardware event-based sampling may cause unpredictable system behavior due to a known hardware issue. To avoid this, you are not recommended to run General Exploration or Custom Hardware event-based analysis with precise events on these systems unless a BIOS workaround for the erratum is provided.

VTune Amplifier may detect which timer source to use incorrectly on Intel® Xeon® processor E5-XXXX processors (200287361)

In User-mode Sampling and Tracing based analysis (Hotspots, Concurrency, Locks and Waits), the following message may be displayed in command line or Debug Window:

Warning Cannot load data file `<path>\data.0\18385-18389.0.trace' (SampleCallback: timestamps aren't ascended!).

To work around the problem collect results from command line using the -run-pass-thru option:

amplxe-cl -collect hotspots -run-pass-thru=-timestamp=sys -- <application>

Hardware event-based analysis does not work if more than 128 events are gathered simultaneously (200293868)

Decrease number of PMU events in analysis settings to resolve it.

Results should be closed before comparing them (200236090)

VTune Amplifier does not support opening the same result twice. Due to that limitation it is not possible to compare (via the Compare button) results if one of them is already opened. You should close results first then compare them.

ITT API task or frame is not shown in results if its end occurs when collector is inactive (200331811)

When ITT task or frame end notification occurs after collection was paused, or detach or stop command issued, the frame or task is not displayed in the result.

An application may experience the stack overflow exception when running under the VTune Amplifier (200249394)

An application allocating massive chunks of memory on a thread stack may experience the stack overflow exception and fail when running under the VTune Amplifier, while running flawlessly on its own. This happens because the VTune Amplifier requires additional space on an application thread stack for profiling needs. To work around this problem, consider using larger thread stack space.

JIT writer API cannot handle too long file names on Windows (200587412)

This issue happens when file name of JIT trace file is longer than 260 symbols. VTune is then not able to generate a proper result when the result directory has long name.

VTune Amplifier is not able to resolve debug information when an application is compiled with the “/DEBUG:FASTLINK” option. (200414493)

This issue is prevalent only in Microsoft* Visual Studio 2015. To fix this issue, please use the “/DEBUG” option instead. For more information, please see HTTPS://BLOGS.MSDN.MICROSOFT.COM/VCBLOG/2015/10/16/DEBUGFASTLINK-FOR-VS2015-UPDATE-1.

VTune Amplifier target executables do not work on Yocto Project 1.5 x64 due to different paths to ld (200507491)

Error message: "-sh: ./amplxe-runss: No such file or directory". Usually ld is located in /lib64/ld-linux-x86-64.so.2 but on Yocto 1.5 x64 it is located in /lib/ld-linux-x86-64.so.2. The workaround is to create /lib64/ld-linux-x86-64.so.2 as a symlink to /lib/ld-linux-x86-64.so.2.

Windows* Host Limitations

Thread stack size limitation (200108571)

VTune Amplifier may crash with the following error message: Error: failed to create a sampling thread: not enough storage is available to process this command. This happens when the profiled application has big reserved and committed thread stack size (/STACK:reserve[,commit] command line switch of link.exe). The suggested workaround is reducing the reserved/committed thread stack size to profile the target.

Incorrect timing results when running on a 32-bit virtual machine (200137061)

VTune Amplifier may fail to collect correct timing data when running on a virtual machine with problematic virtualization of time stamp counters. In this case the VTune Amplifier throws a warning message:

Warning Cannot load data file '<path_to_a_trace_file>.trace' (syncAcquiredHandler: timestamps aren't ascended!)

Uninstalling limitation: pin.exe stays running after detaching. (200092295)

VTune Amplifier cannot be uninstalled after attaching to the target to be profiled until running the target is over. The cause is that pin.exe keeps working after detaching from the target and exits only after the profiled application/process execution finishes.

Second attach to the same application should print an error and exit immediately (200092650)

VTune Amplifier allows running the analysis while the previous one is in progress but does not store any data for the second analysis run.

Truncated .NET* module names may be displayed in results view (200199458)

When viewing results collected for a .NET application, you may observe truncated .NET module names. Please make sure a system was rebooted after installing the .NET application and before profiling with the VTune Amplifier.

.NET modules loaded dynamically via Reflection API are displayed as "unknown" hotspots (200088121)

If dynamic .NET modules (e.g. loaded via Assembly.LoadFrom) are used in target application, VTune Amplifier will show them as "unknown" functions and modules in hotspots list.

Attachment as Administrator to a process that launched by the 'System' user fails (200259643)

You may use a utility from http://technet.microsoft.com/en-us/sysinternals/bb897553 to profile a system service (for example, w3wp.exe-based code) from the command line using amplxe-cl.exe that is located in <product_install_dir>/bin32. Do the following:

1. Configure the w3wp service to run with the permissions you use to log in: Open IIS Manager, right-click an application pool you are using and set “Process model:Identity” to the account under which w3wp needs to be run.

2. Run the w3wp service and make sure you run it with proper credentials and remember its PID.

3. Start data collection:

   psexec -i 0 /path/to/amplxe-cl.exe -c=hotspots -r /path/for/your/data_dir --target-pid=PID

4. Run your workload.

5. Stop data collection:

   psexec -i 0 /path/to/amplxe-cl.exe -command detach -r /path/for/your/data_dir

6. Open /path/for/your/data_dir in GUI:

   <product_install_dir>/bin32/amplxe-gui /path/to/your/data_dir

Limited support of Windows Store* applications (200299329)

VTune Amplifier supports attaching to Windows Store* applications, but not launching them. Only hardware event-based analysis types are supported.

Microsoft* Visual Studio* 2012 help may be displayed incorrectly (200300692)

On Microsoft* Windows Server 2012* systems, if you have problems viewing Microsoft* Visual Studio* 2012 help, check the settings for Internet Explorer in Tools > Internet Options > Security. To allow correct display of help, in the Internet zone enable MIME Sniffing and Active scripting.

VTune Amplifier analysis may fail on machine with Verdasys Digital Guardian* software installed. (200237470)

User mode sampling and tracing based analysis types (Hotspots, Concurrency, Locks and Waits) run from GUI may fail if Verdasys Digital Guardian* software is installed on the machine. However it is still possible to run collection from command line.

Alternatively EBS collection with stacks can be used, either from GUI or command line.

Analyzed application may crash during analysis if "Symantec Endpoint Protection Application and Device Control" software is installed (200237601)

The issue may occur with user mode sampling and tracing based analysis types (Hotspots, Concurrency, and Locks and Waits). Ways to overcome the problem:

• If user mode sampling and tracing based analysis is needed exclude the analyzed application from the list of monitored applications of "Symantec Endpoint Protection Application and Device Control" software.

• Use the Advanced Hotspots analysis with the Collect stacks option turned on instead.

Documentation cannot be opened in Microsoft Internet Explorer* 10 on Windows Server* 2012 (200340007)

To correct the problem modify security settings in Microsoft Internet Explorer* 10. From Tools > Internet Options > Security, add “about:internet” to the list of trusted sites.

Child process analysis does not work for EBS analysis types if process is run from script using "start" command (200342928)

If a process is started from a batch file by the "start" command, it does not have original command interpreter as a parent process. So the new process cannot be identified as a child and not profiled. This is true for all Hardware event-based analyses. Possible workarounds:

• Use user-mode sampling and tracing based analysis types instead

• Use "call" command in a batch file instead of "start"

• Use "attach to process" collection mode to connect directly to the process of interest

Collection of some GPU analysis metrics should be enabled in BIOS for 3rd Generation Intel® Core™ processors (200342983)

Some systems disable collection of extended metrics such as L3 misses, memory accesses, sampler busyness, SLM accesses, etc. in the BIOS. On some systems, but not all, they can be enabled by changing a bios option. The presence or absence of the option and its name are BIOS vendor specific. Look for something like an “Intel(R) Graphics Performance Analyzers” option in your BIOS and set it to “Enabled ". Note that this option is BIOS vendor specific, may not always be present and may be named differently. Check the BIOS options on your system for details.

Results may contain process name cut on the 14th character (200401361)

VTune Amplifier may cut long process name on the 14th character in results collected with EBS analysis types with stacks. E.g. the result should contain find_hotspots.exe, but it contains only find_hotspots.. This is an operating system limitation.

Warning "Unsigned driver" during installation for sepdrv and vtss drivers on Windows* 7 and Windows* Server 2008 R2 (200574645)

VTune Amplifier hardware event-based sampling drivers (sepdrv.sys and vtss.sys) are signed with digital SHA-2 certificate key for compliance with Windows 10 requirements.

To install the drivers on Windows* 7 and Windows* Server 2008 R2 operating systems, add functionality for the SHA-2 hashing algorithm to the systems by applying Microsoft Security update 3033929: https://technet.microsoft.com/en-us/library/security/3033929.

Analysis of Processor Graphics hardware events on Windows* OS requires a compatible Intel Graphics Drivers (200586628)

To monitor the Render and GPGPU engine usage, VTune Amplifier requires a compatible Intel Graphics Drivers.

As of July 30 2016, the latest supported version is Intel Beta Graphics Driver for Windows, Version: Beta 15.40.12.4326 .

The analysis may fail with Version: Beta 15.40.18.4380 or newer.

VTune Amplifier cannot load drivers into kernel

Most Android* kernels only allow signed drivers. If you try and install a driver (sep3_10.ko, pax.ko, vtsspp.ko, SOCWATCH1_3.ko or apwr3_1.ko), which has been built after the kernel was built, you will get an error message stating that no signing key is found. To workaround, you must build drivers with the exact signing key created when the Android OS (boot.bin) was built. The easiest way to do that is to use drivers which have been integrated into the kernel.

Windows* OS: VTune Amplifier for Systems target executables do not work on Yocto Project 1.5 x64 due to different paths to ld

Target executables fail with the following message:

-sh: ./amplxe-runss: No such file or directory

Usually ld is located in /lib64/ld-linux-x86-64.so.2 but on Yocto 1.5 x64 it is located in /lib/ld-linux-x86-64.so.2. The workaround is to create /lib64/ld-linux-x86-64.so.2 as a symlink to /lib/ld-linux-x86-64.so.2.

Linux* Host Limitations

Security-enhanced Linux* is not supported (200155374)

Security-enhanced Linux settings (SELinux) are currently not supported by the VTune Amplifier and need to be either disabled or set to permissive for a successful tool suite installation. If your Linux distribution has SELinux enabled the following error message will be issued by the installer: "Your system is protected with Security-enhanced Linux (SELinux). We currently support only "Permissive" mode, which is not found on the system. To rectify this issue, you may either disable SELinux by - setting the line "SELINUX=disabled" in your /etc/sysconfig/selinux file - adding "selinux=0" kernel argument in lilo.conf or grub.conf files or make SELinux mode adjustment by - setting the line "SELINUX=permissive" in your /etc/sysconfig/selinux file or ask your system administrator to make SELinux mode adjustment. You may need to reboot your system after changing the system parameters. More information about SELinux can be found at http://www.nsa.gov/selinux/".

VTune Amplifier user mode collection may fail to run on Ubuntu* (200197563)

VTune Amplifier may fail to collect data for Hotspots, Concurrency, and Locks and Waits analysis types on the Ubuntu operating system. Once a collection is started, the message appears in the output: "Failed to start profiling because the scope of ptrace() system call application is limited. To enable profiling, please set /proc/sys/kernel/yama/ptrace_scope to 0. See the Release Notes for instructions on enabling it permanently."

To workaround this problem for the current session, set contents of the /proc/sys/kernel/yama/ptrace_scope sysctl file to 0.

To make this change permanent, set kernel.yama.ptrace_scope value to 0 at /etc/sysctl.d/10-ptrace.conf file using root permissions and reboot the machine.

Concurrency analysis may provide incorrect Wait time data if Linux futexes are used (200163557)

In certain cases, custom synchronization constructions based on Linux futexes are not detected by the VTune Amplifier. System libraries may also use such constructions. To ensure Wait time correctness in the Concurrency analysis, use syscall(SYS_futex, ...) API in your code.

VTune Amplifier may cause KVM guest virtual machine to crash (200384245)

In some cases, when you run Event-Based Sampling analysis on a host machine, a guest KVM virtual machine may experience kernel panic. This happens only if precise events are used, for example, with General Exploration analysis type. Upgrade KVM to a newer version, there is a KVM patch that fixes the problem.

VTune Amplifier GUI may not have scrollbars on Ubuntu* OS (200534347)

On Ubuntu 12.04 and newer with the overlay scrollbars style, there may be no scrollbars available in the VTune Amplifier GUI. To get them shown, change the scrollbar style by invoking the command below before running amplxe-gui:

• On Ubuntu 12.x:

  gsettings set org.gnome.desktop.interface ubuntu-overlay-scrollbars false

• On Ubuntu 13.x and newer:

  gsettings set com.canonical.desktop.interface scrollbar-mode normal

Symbols are not resolved for binaries remapped with hugtlbfs utility (200244405)

hugetlbfs remaps segments from executable file to its temporary file system or to anonymous memory regions. VTune Amplifier can’t map those segments to the original executable.

Workaround for this problem is to rename the original executable to the one that hugetlb exposes, i.e. the module name that you see in VTune Amplifier results.

my_exe (original executable) -> my_exe_32_2 (file name on hugetlb file system in case of sharing between processes)

my_exe (original executable) -> libhugetlbfs.tmp.<random hash> (memory region name in case of anonymous mappings)

Running other PMU-based tools simultaneously with hardware event-based sampling collection is not supported (200166101)

The Sampling Driver requires exclusive use of the PMU resources. Running multiple PMU based tools will cause incorrect results and/or system instability.

Hotspots, Concurrency and Locks and Waits analysis types may not work on executables that do not depend on the libpthread.so.0 library (200208975)

There is currently a limitation in the product regarding profiling application targets where the executable does not depend on the libpthread.so.0 library. The message "Link libpthread.so to the application statically and restart profiling" appears when profiling an application where program image does not depend on libpthread.so.0 but then it dlopen()-s a shared library which does depend on libpthread.so.0. The collector is not able to follow the program execution and module load/unload so the collection results are likely to be misleading. A workaround is to set "LD_PRELOAD=libpthread.so.0" before running the collection.

Opening results significantly delayed on Linux systems configured with "large pages" (200215471)

To work around this issue make sure that you have hugectl utility and libhugetlbfs library on the system. VTune Amplifier can be started this way:

hugectrl --heap <amplxe install dir>/bin32/amplxe-gui

LD_PRELOAD=libhugetlbfs.so <amplxe install dir>/bin64/amplxe-gui

Help TOC is truncated in some Linux browsers (200272063)

When using certain HTML browsers to view the VTune Amplifier offline documentation, if the Contents tab width appears truncated and hides some of the topic titles:

• Click the Index (or Search) button

• Click the Contents button

Decreasing sampling interval for user-mode sampling and tracing collection may lead to wrong CPU usage data (200296537)

User-mode sampling and tracing analysis technology is based on OS timers which cannot tick faster than HZ value configured during kernel compilation. Sampling interval should not be less than HZ value.

User-mode sampling and tracing collection may cause an error when profiling COI/SCIF application on Intel® Xeon Phi™ processor (200234639)

If you get a COI buffer error with User-mode sampling and tracing collection, use hardware event-based analysis instead.

Collection fails with error "No CONFIG_PERF_EVENTS=y kernel support configured" (200372350)

Driverless EBS collection on Linux can fail with the error: "No CONFIG_PERF_EVENTS=y kernel support configured" even having the kernel config has been set. This is a known Linux kernel issue that is resolved in kernel version 4.1. There is a simple patch that provides a workaround: http://halobates.de/ivb-allow-mem-load-uops

User tasks, events and frames marked with ITT APIs may not be shown if target application is finished by Ctrl+C (200304207)

Use another method to stop application, or VTune Amplifier "stop" command.

When installing on a Xen* virtual machine, it may happen that installation script exits claiming CPU is unsupported (200294340)

To skip the check for CPU model, add --ignore-cpu parameter to install script command line:

./install.sh --ignore-cpu

VTune Amplifier help does not open from GUI on some Linux systems (200377881)

On some Linux systems, like Wind River Linux, default ways to open web browser may not work. You may export environment variable ‘BROWSER’ (before starting VTune Amplifier) with the path to web browser to get VTune Amplifier help working.

For example:

>export BROWSER=/usr/bin/firefox

VTune Amplifier user APIs are not supported for static binaries (200279211)

To use ITT and JIT APIs with software based collectors (Hotspots, Concurrency, Locks and Waits) user needs to link their application dynamically. Otherwise ITT and JIT API notifications will be missing in the result.

Event-based sampling driver fails to build on Yocto Project 1.6 Intel x86_86 BSPs due to missing CONFIG_COMPAT #define in linux kernel headers (200359539)

Sampling driver fails to build on Yocto x86_64 BSPs images that do not have “CONFIG_COMPAT=y” setting (https://bugzilla.yoctoproject.org/show_bug.cgi?id=6777)

To resolve the issue, you need to re-build the image with the option manually.

Change kernel configuration according to http://www.yoctoproject.org/docs/1.6.1/kernel-dev/kernel-dev.html#changing-the-configuration:

1. Create the compat.cfg file in meta-yocto-bsp/recipes-kernel/linux/files/ directory with content:

   CONFIG_IA32_EMULATION=y

   CONFIG_COMPAT=y

2. Add the following strings to meta-yocto-bsp/recipes-kernel/linux/linux-yocto_3.10.bbappend

   FILESEXTRAPATHS_prepend := "${THISDIR}/files:"

   SRC_URI += file://compat.cfg

3. Clean and build a modified kernel according to http://www.yoctoproject.org/docs/1.6.1/dev-manual/dev-manual.html#patching-the-kernel and http://www.yoctoproject.org/docs/1.6.1/dev-manual/dev-manual.html#build-the-modified-qemu-kernel-image:

   $ bitbake linux-yocto -c cleansstate

   $ bitbake -k linux-yocto

4. Build image:

   $ bitbake core-image-sato

Under no circumstances and under no legal theory, whether tort (including negligence), contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as permitted above, be liable to You for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for lost profits, loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, even if such party shall have been informed of the possibility of such damages. This limitation of liability shall not apply to liability for death or personal injury resulting from such party’s negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You.

8. Litigation

Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party’s ability to bring cross-claims or counter-claims.

9. Miscellaneous

This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor.

• npm is a package manager program located at deps/npm.

  npm's license follows:

  Copyright (c) Isaac Z. Schlueter

  All rights reserved.

  npm is released under the Artistic 2.0 License.

  The text of the License follows:

  The Artistic License 2.0

  Copyright (c) 2000-2006, The Perl Foundation.

  Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

  Preamble

  This license establishes the terms under which a given free software Package may be copied, modified, distributed, and/or redistributed.

  The intent is that the Copyright Holder maintains some artistic control over the development of that Package while still keeping the Package available as open source and free software.

  You are always permitted to make arrangements wholly outside of this license directly with the Copyright Holder of a given Package. If the terms of this license do not permit the full use that you propose to make of the Package, you should contact the Copyright Holder and seek a different licensing arrangement.

  Definitions

  "Copyright Holder" means the individual(s) or organization(s) named in the copyright notice for the entire Package.

  "Contributor" means any party that has contributed code or other material to the Package, in accordance with the Copyright Holder's procedures.

  "You" and "your" means any person who would like to copy, distribute, or modify the Package.

  "Package" means the collection of files distributed by the Copyright Holder, and derivatives of that collection and/or of those files. A given Package may consist of either the Standard Version, or a Modified Version.

  "Distribute" means providing a copy of the Package or making it accessible to anyone else, or in the case of a company or organization, to others outside of your company or organization.

  "Distributor Fee" means any fee that you charge for Distributing this Package or providing support for this Package to another party. It does not mean licensing fees.

  "Standard Version" refers to the Package if it has not been modified, or has been modified only in ways explicitly requested by the Copyright Holder.

  "Modified Version" means the Package, if it has been changed, and such changes were not explicitly requested by the Copyright Holder.

  "Original License" means this Artistic License as Distributed with the Standard Version of the Package, in its current version or as it may be modified by The Perl Foundation in the future.

  "Source" form means the source code, documentation source, and configuration files for the Package.

  "Compiled" form means the compiled bytecode, object code, binary, or any other form resulting from mechanical transformation or translation of the Source form.

  Permission for Use and Modification Without Distribution

  (1) You are permitted to use the Standard Version and create and use Modified Versions for any purpose without restriction, provided that you do not Distribute the Modified Version.

  Permissions for Redistribution of the Standard Version

  (2) You may Distribute verbatim copies of the Source form of the Standard Version of this Package in any medium without restriction, either gratis or for a Distributor Fee, provided that you duplicate all of the original copyright notices and associated disclaimers. At your discretion, such verbatim copies may or may not include a Compiled form of the Package.

  (3) You may apply any bug fixes, portability changes, and other modifications made available from the Copyright Holder. The resulting Package will still be considered the Standard Version, and as such will be subject to the Original License.

  Distribution of Modified Versions of the Package as Source

  (4) You may Distribute your Modified Version as Source (either gratis or for a Distributor Fee, and with or without a Compiled form of the Modified Version) provided that you clearly document how it differs from the Standard Version, including, but not limited to, documenting any non-standard features, executables, or modules, and provided that you do at least ONE of the following:

  (a) make the Modified Version available to the Copyright Holder of the Standard Version, under the Original License, so that the Copyright Holder may include your modifications in the Standard Version.

  (b) ensure that installation of your Modified Version does not prevent the user installing or running the Standard Version. In addition, the Modified Version must bear a name that is different from the name of the Standard Version.

  (c) allow anyone who receives a copy of the Modified Version to make the Source form of the Modified Version available to others under

  (i) the Original License or

  (ii) a license that permits the licensee to freely copy, modify and redistribute the Modified Version using the same licensing terms that apply to the copy that the licensee received, and requires that the Source form of the Modified Version, and of any works derived from it, be made freely available in that license fees are prohibited but Distributor Fees are allowed.

  Distribution of Compiled Forms of the Standard Version or Modified Versions without the Source

  (5) You may Distribute Compiled forms of the Standard Version without the Source, provided that you include complete instructions on how to get the Source of the Standard Version. Such instructions must be valid at the time of your distribution. If these instructions, at any time while you are carrying out such distribution, become invalid, you must provide new instructions on demand or cease further distribution. If you provide valid instructions or cease distribution within thirty days after you become aware that the instructions are invalid, then you do not forfeit any of your rights under this license.

  (6) You may Distribute a Modified Version in Compiled form without the Source, provided that you comply with Section 4 with respect to the Source of the Modified Version.

  Aggregating or Linking the Package

  (7) You may aggregate the Package (either the Standard Version or Modified Version) with other packages and Distribute the resulting aggregation provided that you do not charge a licensing fee for the Package. Distributor Fees are permitted, and licensing fees for other components in the aggregation are permitted. The terms of this license apply to the use and Distribution of the Standard or Modified Versions as included in the aggregation.

  (8) You are permitted to link Modified and Standard Versions with other works, to embed the Package in a larger work of your own, or to build stand-alone binary or bytecode versions of applications that include the Package, and Distribute the result without restriction, provided the result does not expose a direct interface to the Package.

  Items That are Not Considered Part of a Modified Version

  (9) Works (including, but not limited to, modules and scripts) that merely extend or make use of the Package, do not, by themselves, cause the Package to be a Modified Version. In addition, such works are not considered parts of the Package itself, and are not subject to the terms of this license.

  General Provisions

  (10) Any use, modification, and distribution of the Standard or Modified Versions is governed by this Artistic License. By using, modifying or distributing the Package, you accept this license. Do not use, modify, or distribute the Package, if you do not accept this license.

  (11) If your Modified Version has been derived from a Modified Version made by someone other than you, you are nevertheless required to ensure that your Modified Version complies with the requirements of this license.

  (12) This license does not grant you the right to use any trademark, service mark, tradename, or logo of the Copyright Holder.

  (13) This license includes the non-exclusive, worldwide, free-of-charge patent license to make, have made, use, offer to sell, sell, import and otherwise transfer the Package with respect to any patent claims licensable by the Copyright Holder that are necessarily infringed by the Package. If you institute patent litigation (including a cross-claim or counterclaim) against any party alleging that the Package constitutes direct or contributory patent infringement, then this Artistic License to you shall terminate on the date that such litigation is filed.

  (14) Disclaimer of Warranty:

  THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

   A large portion of the dictionary entries originate from ICOT Free Software. The following conditions for ICOT Free Software applies to the current dictionary as well.

   Each User may also freely distribute the Program, whether in its original form or modified, to any third party or parties, PROVIDED that the provisions of Section 3 ("NO WARRANTY") will ALWAYS appear on, or be attached to, the Program, which is distributed substantially in the same form as set out herein and that such intended distribution, if actually made, will neither violate or otherwise contravene any of the laws and regulations of the countries having jurisdiction over the User or the intended distribution itself.

   NO WARRANTY

   The program was produced on an experimental basis in the course of the research and development conducted during the project and is provided to users as so produced on an experimental basis. Accordingly, the program is provided without any warranty whatsoever, whether express, implied, statutory or otherwise. The term "warranty" used herein includes, but is not limited to, any warranty of the quality, performance, merchantability and fitness for a particular purpose of the program and the nonexistence of any infringement or violation of any right of any third party.

   Each user of the program will agree and understand, and be deemed to have agreed and understood, that there is no warranty whatsoever for the program and, accordingly, the entire risk arising from or otherwise connected with the program is assumed by the user.

   Therefore, neither ICOT, the copyright holder, or any other organization that participated in or was otherwise related to the development of the program and their respective officials, directors, officers and other employees shall be held liable for any and all damages, including, without limitation, general, special, incidental and consequential damages, arising out of or otherwise in connection with the use or inability to use the program or any product, material or result produced or otherwise obtained by using the program, regardless of whether they have been advised of, or otherwise had knowledge of, the possibility of such damages at any time during the project or thereafter. Each user will be deemed to have agreed to the foregoing by his or her commencement of use of the program. The term "use" as used herein includes, but is not limited to, the use, modification, copying and distribution of the program and the production of secondary products from the program.

   In the case where the program, whether in its original form or modified, was distributed or delivered to or received by a user from any person, organization or entity other than ICOT, unless it makes or grants independently of ICOT any specific warranty to the user in writing, such person, organization or entity, will also be exempted from and not be held liable to the user for any such damages as noted above as far as the program is concerned.

5. Time Zone Database

   ICU uses the public domain data and code derived from Time Zone Database for its time zone support. The ownership of the TZ database is explained in BCP 175: Procedure for Maintaining the Time Zone Database section 7.

   7. Database Ownership

   The TZ database itself is not an IETF Contribution or an IETF document. Rather it is a pre-existing and regularly updated work that is in the public domain, and is intended to remain in the public domain. Therefore, BCPs 78 [RFC5378] and 79 [RFC3979] do not apply to the TZ Database or contributions that individuals make to it. Should any claims be made and substantiated against the TZ Database, the organization that is providing the IANA Considerations defined in this RFC, under the memorandum of understanding with the IETF, currently ICANN, may act in accordance with all competent court orders. No ownership claims will be made by ICANN or the IETF Trust on the database or the code. Any person making a contribution to the database or code waives all rights to future claims in that contribution or in the TZ Database.

We welcome the use of this software as a component of commercial products.

No royalty is required, but we do ask for an acknowledgement in product documentation, as described under LEGAL ISSUES.

LEGAL ISSUES

In plain English:

1. We don't promise that this software works. (But if you find any bugs, please let us know!)

2. You can use this software for whatever you want. You don't have to pay us.

3. You may not pretend that you wrote this software. If you use it in a program, you must acknowledge somewhere in your documentation that you've used the IJG code.

In legalese:

The authors make NO WARRANTY or representation, either express or implied, with respect to this software, its quality, accuracy, merchantability, or fitness for a particular purpose. This software is provided "AS IS", and you,

its user, assume the entire risk as to its quality and accuracy.

This software is copyright (C) 1991-1998, Thomas G. Lane.

All Rights Reserved except as specified below.

Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for any purpose, without fee, subject to these conditions:

(1) If any part of the source code for this software is distributed, then this README file must be included, with this copyright and no-warranty notice unaltered; and any additions, deletions, or changes to the original files must be clearly indicated in accompanying documentation.

(2) If only executable code is distributed, then the accompanying documentation must state that "this software is based in part on the work of the Independent JPEG Group".

(3) Permission for use of this software is granted only if the user accepts full responsibility for any undesirable consequences; the authors accept NO LIABILITY for damages of any kind.

These conditions apply to any software derived from or based on the IJG code, not just to the unmodified library. If you use our work, you ought to acknowledge us.

Permission is NOT granted for the use of any IJG author's name or company name in advertising or publicity relating to this software or products derived from it. This software may be referred to only as "the Independent JPEG Group's software".

We specifically permit and encourage the use of this software as the basis of commercial products, provided that all warranty or liability claims are assumed by the product vendor.

ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its copyright holder, Aladdin Enterprises of Menlo Park, CA.

ansi2knr.c is NOT covered by the above copyright and conditions, but instead by the usual distribution terms of the Free Software Foundation; principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.) However, since ansi2knr.c is not needed as part of any program generated from the IJG code, this does not limit you more than the foregoing paragraphs do.

The Unix configuration script "configure" was produced with GNU Autoconf. It is copyright by the Free Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess, config.sub, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely distributable.

It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM, AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software. (Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely that very many implementations will support it.) So far as we are aware, there are no patent restrictions on the remaining code.

The IJG distribution formerly included code to read and write GIF files. To avoid entanglement with the Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been simplified to produce "uncompressed GIFs". This technique does not use the LZW algorithm; the resulting GIF files are larger than usual, but are readable by all standard GIF decoders.

We are required to state that "The Graphics Interchange Format(c) is the Copyright property of CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe Incorporated."

HPC Performance Characterization Analysis improvements

The HPC Performance Characterization Analysis has received several improvements.

Increased detail and structure for the vector efficiency metrics based on FLOP counters in the FPU Utilization section help diagnose the reason for low utilization connected with poor vector code generation. Relevant metrics include:

• Vector Capacity Usage
• FP Instruction Mix
• FP Arithmetic Instructions per Memory Read or Write
• SP FLOPs per Cycle (may indicate memory bandwidth bound code)

For MPI applications, the MPI Imbalance metric shows CPU time spent by ranks spinning in waits on communication operations, normalized by the number of ranks on the profiling node. The metric issue detection description generation is based on minimal MPI Busy Wait time by ranks. If the minimal MPI Busy Wait time by ranks is not significant, then the rank with the minimal time most likely lies on the critical path of application execution. In this case, review the CPU utilization metrics by this rank.

The Top Loops/Functions with FPU Usage by CPU Time table shows the top functions that contain floating point operations, sorted by CPU time. The FPU Utilization column provides issue descriptions based on whether a loop/function is bandwidth bound, whether it is vectorized or scalar, and what instruction set it's using.

For Intel Xeon Phi processors (codenamed Knights Landing), the following FPU metrics are available instead of FLOP counters:

• SIMD instructions per cycle
• Fraction of packed SIMD instructions vs scalar SIMD instructions per cycle
• Vector instruction set for loops based on static analysis

DRAM Bandwidth Bound metric

A new metric is available in the Memory Usage viewpoint for the Memory Access and HPC Performance Characterization analyses which indicates whether your system spent much time heavily utilizing the DRAM bandwidth. The calculation of this metric relies on accurate maximum system DRAM bandwidth measurement, and depends on the number of sockets on your system.

GPU Hotspots Summary improvements

The GPU Hotspots viewpoint's Summary tab has been extended to display more information. The GPU Usage section can be used to identify whether the GPU was properly utilized. The Packet Queue Depth Histogram can be used to estimate the GPU software queue depth per GPU engine during the target run. Ideally, your goal is an effective GPU engine utilization with evenly loaded queues and minimal duration for the zero queue depth.

For a high-level view of the DMA packet execution during the target run, review the Packet Duration Histogram. Select a required packet type from the drop-down menu and identify how effectively these packets were executed on the GPU. Having high packet count values for the minimal duration is optimal.

KVM Guest OS Profiling

If you are a system developer and interested in the performance analysis of a guest Linux* system, use Intel VTune Amplifier for performance analysis of this guest Linux* OS via Kernel-based Virtual Machine (KVM) from the host system. Depending on your analysis target, you may choose either of the following usage models for KVM guest OS profiling:

• Guest system and KVM modules analysis
• Application analysis on the KVM guest system

Locks & Waits analysis for Python

Locks and Waits analysis can now be used to tune threaded performance of mixed Python* and native code. View Sync Objects in the grid, see Python frames in the Call Stack, an define which sync objects are the Global Interpreter Lock (GIL), either by wait count or by callstack. Drill down to Python source to explore thread synchronization issues at code level. For more information on how to configure the analysis, see the Python* Code Analysis product help article.

Intel® Xeon Phi™ Processor Support

Intel® VTune™ Amplifier now supports the Intel® Xeon Phi™ Processor codenamed Knights Landing.

Decide how to use MCDRAM (the high bandwidth memory) effectively using Memory Access Analysis, analyze the scalability of MPI and OpenMP* with HPC Performance Characterization Analysis, and explore the microarchitecture efficiency with General Exploration Analysis.

HPC Performance

The HPC Performance Characterization Analysis explores the three key performance aspects of application scalability:

• Threading: CPU Utilization with parallel efficiency for MPI and OpenMP*. Explore the serial vs parallel time and the top OpenMP regions by potential gain.
• Memory Access Efficiency: includes bandwidth utilization and stalls by memory hierarchy.
• FPU utilization: includes basic vectorization metrics.

See the analysis usage example in the Analyzing an OpenMP and MPI Application web-based tutorial, which provides a hands-on exercise to identify memory utilization inefficiencies and load imbalance for a sample hybrid application.

Memory Access Analysis

The Memory Access Analysis has been improved. In addition to support for the Intel Xeon Phi processors, it now supports custom memory allocators, and includes automatic detection of maximum system DRAM bandwidth characteristics and scaling bandwidth data from that maximum. This allows users to easily see how they actually utilize the available DRAM bandwidth, rather than just raw GB/S values. The QPI bandwidth has been split to Total, Outgoing, and Incoming, instead of just the total. The workflow has been optimized for identifying the top memory objects with high bandwidth utilization per domain. Finally, no special drivers are required on Linux*; this analysis type can now use standard Linux* perf to collect data, eliminating the need for root to install other drivers.

Disk I/O Analysis (Preview)

The Disk Input and Output analysis for HDD, SATA, or NVMe SSD monitors utilization of the disk subsystem, CPU, and PCle buses, and helps to identify long latency of I/O requests and imbalance between I/O and compute operations.

See the Analyzing Input/Output Waits tutorial for a hands-on exercise with sample code on Linux*.

GPU analysis improvements

GPU Hotspots Analysis is intended for GPU-bound applications, and provides options to analyze execution of OpenCL™ kernels and Intel® Media™ SKD tasks.

The GPU Analysis Summary provides a set of metrics to estimate the GPU utilization per engine, identify stalled or idle execution units, and explore the most typical problems with low occupancy or frequent sampler accesses. Navigate from the Hottest GPU computing tasks summary to the details provided in the graphics tab.

Intel VTune Amplifier now also supports the detection of OpenCL 2.0 Shared Virtual Memory (SVM) usage types per kernel instance.

For more information, see Using Intel VTune Amplifier to Optimize Media & Video Applications.

Usability Improvements

Remote usage and Command Line usage have been improved. Use the Arbitrary target GUI configuration to generate a command line for performance analysis on a system that is not accessible from the current host.

MPI analysis has been extended with the event-based sampling collection supported for multiple ranks per node with an arbitrary MPI launcher and natural syntax. Use the MPI launcher option in the arbitrary targets configuration to automatically generate a command line for MPI analysis from the GUI.

An option for enabling and disabling the OpenMP regions analysis has been added to selected analysis configurations.

Support has been added for the Attach To Process target type with event-based sampling for low-privilege Java* daemons on Linux*.
