Running Windows 10 version 1903 (build 18362/239), Microsoft Visual Studio 2019 version 16.1.6.  I installed Intel Parallel Studio XE 2019 Update 4.  Click the VTune button on the Visual Studio menu bar. A VTune window pops up but only the menu bar and window border are drawn. If I minimize the Visual Studio app and then maximize, the VTune client window shows black. Resizing the VTune window does not help. Screen capture attached to this message. Some windows error messages in the dxdiag report are listed at the end of this message. These are not helpful for diagnosing. The behavior occurs on my desktop computer and on my Microsoft Surface Book computer (same OS/VS/VTune on these computers). Is this a known problem? If so, when is a fix available? Thank you.

Hello, I am trying to profile a Java application that has been run using a jar.

I was interested in hotspots but I see issues in the result the profiler pops up -

I am using OpenJDK-8 on Ubuntu 18.04 on a VM in VmWare ESXI. I understand that hardware events might not be captured at all. 

Please help me understand any lacking in the setup. Is there any general Java profiling guide I should follow?

Thanks

1. Than i try launch VTune Amplifier 2019, few minutes I see

In next this screen hides and it all, nothing happened. In Task manager i see:

2. In VS 2019 16.2.0 Launch not work

3. Other menu items ignore click, nothing happened too.

Hi,

I dowloaded the trial version of Intel Vtune Amplifier 2019 and followed all the steps in the link below to integrate it to VS2019 : 

https://software.intel.com/en-us/vtune-amplifier-help-microsoft-visual-s...

Unfortunately, I can't get Vtune Amplifier in the tools menu. Doesn't the trial version offer this integration or is it not compatible with VS2019?

Could you please help us with this problem ?

Thanks.

Base installation worked fine, collector worked fine (although an unmet/unadvertised required "dstat" package had to be manually installed). But "server" appears to have a bit of a showstopper.

Oracle Java downloads now require logging in to an Oracle account to download Java updates, like the latest Oracle Java 8u211 / Java SE 8u212. Because of this I cannot update the PPA with the latest Java (and the old links were broken by Oracle).

For this reason, THIS PPA IS DISCONTINUED (unless I find some way around this limitation).....

Package oracle-java8-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or....

Aside from downgrading the OS, or finding another system for this experiment is there an easy path forward? Is there some reason why we're sticking with java8?  As this u19 system is a KVM host for several experimental VMs, I did briefly try to install under ubuntu 16 ... but the base install (the step directly after tar xvzf *.tar.gz) fails with "unsupported CPU" ... doubtless because when I set up the VM I didn't specially configure it for vtune ...

I have switched to using Intel Cluster Studio XE tools 2019 Update 4 but now both Vtune Amplifier and Thread Advisor refuse to run claiming that an X11 library is missing. 

mtml@llin763[pts/1]demo $ amplxe-gui: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory

This is a CentOS Linux release 7.6.1810 (Core)

I do not have this problem with 2019 Update 1  . This library is missing from CentOS 7u6 but it is present in CentOS 6. 

Any suggestions?Thanks

I'm using event based sampling to collect performance metrics (mainly cache misses) for a simple matrix multiplication code. However, the gathered values from Vtune are drastically different from the values i gathered using PAPI (same code, with same matrix dimensions).

I'm running the program on a single core which i have exclusive access to. Is there some detail that i'm missing here?

Example: for a simple matrix multiplication of 1K x 1K elements,

- using vtune: amplxe-cl -collect-with runsa -knob event-config=MEM_LOAD_RETIRED.L1_MISS matmul

Gives me the result: Hardware Event Type       Hardware Event Count:Self  Hardware Event Sample Count:Self  Events Per Sample
------------------------  -------------------------  --------------------------------  -----------------
MEM_LOAD_RETIRED.L1_MISS                     100003                                 1  100003

- and the same code using papi with the event PAPI_L1_TCM:

Event 0 count = 74
Time taken: 3.822580 seconds
GFLOPS = 0.523207
 

- and again with papi low level API using the the event MEM_LOAD_RETIRED.L1_MISS

Event count 30332
Time taken: 3.077956 seconds
GFLOPS = 0.649782
 

Some papi forum posts mentioned that vtune gathers system-wide metrics, while papi measures process-based metrics. Even if this was true, the drastic difference still doesn't make sense to me.

Any help/guidance is appreciated!

Thanks!

Hi,

I am getting the following error when doing a Vtune collection. I have tried using Vtune versions 2019 updates 4 and 5.

Hi all,

We were trying to monitor the memory activities to check the Number of Memory Partial Writes and the ditribution of memory accesses among the Memory Channels. We came across vtbwrun tool (which is included in the Intel® VTune™ Performance Analyzer), however on installing the VTune, we are unable to find the tool.

If someone could point out to the tool or any other tool to monitor activities would be really helpful.

Thank you!

Hi,

I'm running VTune Amplifier 2019.5.0.601413 with command line and get the error while trying to collect uarch-exploration or memory-access. Here's the full output:

amplxe: Warning: To profile kernel modules during the session, make sure they are available in the /lib/modules/kernel_version/ location.
amplxe: Error: The following events cannot be collected: MEM_LOAD_UOPS_LLC_MISS_RETIRED.LOCAL_DRAM,MEM_LOAD_UOPS_LLC_MISS_RETIRED.REMOTE_DRAM,MEM_LOAD_UOPS_LLC_MISS_RETIRED.REMOTE_FWD,MEM_LOAD_UOPS_LLC_MISS_RETIRED.REMOTE_HITM,MEM_LOAD_UOPS_RETIRED.L1_MISS. Consider removing the events from the collection, loading the VTune Amplifier sampling driver using the root credentials, or updating the OS kernel.
amplxe: Collection failed.

I'm running from native Ubuntu 14.04 on an ivy bridge CPU. The above hardware events, as described in the error, can be collected using PCM library though. I was able to modify those control registers and read out contents of the counters.

Could you please help? Thanks!

Running Windows 10 Pro version 1903. Running Microsoft Visual Studio 2019 version 16.2.4. Intel Parallel Studio XE 2019 Update 4 was added as an extension. I launched VTune Welcome Page from the menu bar icon. The window that usually contains "Configure Analysis..." was blank. I decided to open a file in the RECENT RESULTS list. An Open file dialog is launched asking me to select a VTune results file, which indicates the results file cannot be found (it does exist). I press the Cancel button without navigating away from the default folder the dialog uses. The dialog closes but then it relaunches itself. Cancel again, dialog closes and launches again (etc.).

I then navigated to the VTune results file and opened it. Closed the file. Launched VTune Welcome page again from the menu bar icon. This time the "Configure Analysis..." shows up in the window. When I click on the RECENT RESULTS list on any file, that file is found and opened (no file dialog this time).

I can now run the tool, but just posting the scenario in case other folks run into the same problem.

During a recent webinar, I believe I heard it claimed that there's less than 5% overhead for running the collector. Just how is that computed? There's whatever the impact is running a workload after "vpp start" and that does seem relatively minimal (I say seems, because I'm using a desktop not a dedicated server) but ...

1. Just what resources are being used (large memory array? temp file(s)??). 
2. Just what is the impact of vpp stop ? It seems to spawn a very CPU intensive python task ... which runs for several minutes ... that seems likely to have noticable impact...
3. Similarly for vpp upload (is that "just" a ftp (scp?) transfer? 

I would like to be able to deploy vpp to production servers ... but I expect significant pushback if there's periodic impact to running services (obviously, we'll have to do our own measurements) ... if there are ways to mitigate impact (is there a vpp stop internal step which would just store the file, and allow for processing (whatever is going on) to be done off the SUT? Can it be configured to do its work with lower impact (perhaps taking longer to execute ... if/when we're in production it won't matter how long it takes for the results to become available...)

is there some way to apply vpp to itself? that is to use another instance to monitor what's going on during the vpp stop? That might provide compelling evidence of minimal impact ... if, it is, in fact, minimal during this phase of processing.

ON an unrelated note, I'm more than a little disappointed that I didn't get any responses from my Ubuntu19 installation question ...

My reports say "Missing bounds information....collector is missing information about Max Memory Bandwidth) to collect this data reinstall and rerun the data collector" as this is a fresh installation (CentOS 7.6) how does this omission come about?

vpp: aliased to /opt/intel/vtune_amplifier/vpp/collector/vpp-collect

why would this happen? I did drive the SUT to a load of 60 and swap space was minimal .... 

Hi.

I'm using VTune Amplifier of RHEL 7.2, installed on VirtualBox VM, and trying to analyse C++ application.
VTune attaches to the process (by pid), starts data collection, but when I run test scenario and press 'Stop', it shows me 'No data to show. The collected data is not sufficient.' message on Summary page, and no any information about functions called, their execution time on other pages.

Can you please tell me, why this could happen and how can I fix it? Thanks.

I am trying to profile an MPI+CUDA application using Intel VTune Amplifier on OpenSuse Leap 15.0. However when I pass the -collect option as "cpugpu-concurrency" I am facing an error as below:

amplxe: Warning: Collection of GPU usage events cannot be enabled. i915 ftrace events are not available.
amplxe: Warning: Collection of GPU usage events cannot be enabled. i915 ftrace events are not available.
amplxe: Error: Ftrace is already in use. Make sure to stop previous collection first.
amplxe: Collection failed.
amplxe: Fatal error: Unknown critical error
amplxe: Internal Error
 

I checked the CONFIG_DRM_I915_LOW_LEVEL_TRACEPOINTS option in the config file under boot directory and the following options were not set. 

#
# drm/i915 Debugging
#
# CONFIG_DRM_I915_WERROR is not set
# CONFIG_DRM_I915_DEBUG is not set
# CONFIG_DRM_I915_SW_FENCE_DEBUG_OBJECTS is not set
# CONFIG_DRM_I915_SW_FENCE_CHECK_DAG is not set
# CONFIG_DRM_I915_SELFTEST is not set
# CONFIG_DRM_I915_LOW_LEVEL_TRACEPOINTS is not set
# CONFIG_DRM_I915_DEBUG_VBLANK_EVADE is not set

Can anyone kindly provide the steps to modify the config file and rebuild the kernel for Opensuse Leap 15.0?

Thanks in advance.

Hello guys,

Once I switch to HPC, Microarchitecture Exploration or Memory Access, I'm not able to run it (play button goes grey). Red text appears after description of selected profiling section (Screenshot_2.png). 
Other case is when I'm running Hotspot profiling, Vtune Amplifier crashes. I managed to get part of the log before crashing (Screenshot_3.png). I would really appreciate your help.

OS: Windows Pro
Processor: Intel i7 7700 (3.6 GHz)

All the best,
