Intel® VTune™ Amplifier XE and VTune™ Performance Analyzer

OpenCL GPU analysis working partially

Eingereicht von rahul.garg am

First of all, many thanks to the VTune team to implementing OpenCL GPU profiling to the tool.

I was trying out the tool on a command-line OpenCL application running on the HD 4000. I followed the documentation and was able to enable the GPU profiling support in VTune. I profiled my application and  some metrics such as average execution time of the kernel, EU array busy and stalled work fine. However, some other metrics, such as memory bandwidth, still report 0.0. I have the latest HD 4000 driver installed with OpenCL 1.2 support. My application is not using DirectX, only OpenCL.

Feedback on Update 5 of Intel VTune Amplifier XE 2013

I recently applied Update 5 of Intel VTune Amplifier XE 2013 on Windows 7 Professional ( 64-bit ). At the end of update when I pressed the Finish button Internet Explorer ( IE ) did Not display the Getting Started web-page. IE was in a very strange Not Responding state and after 1 minute of waiting I terminated IE.

That was the only issue I've experienced and a previous Update 4 worked well. Another thing is I think a message:

Defining code regions to profile

Eingereicht von Maxim V. am

Is there any way to define code regions (functions, modules etc) or time frame to profile and ignore anything else. For instance, if I have an application which sets up a large collection of objects (which takes a lot of CPU resources) then runs a relatively fast function A and exits, can I make VTune ignore anything except for A? I know that it is possible to zoom in using the timeline, but I'd rather send notifications from the application. Something like:

PrepareObjects();

StartCollectingData();

A();

StopCollectingData();

Locks and Waits analysis AV on SetEvent

Hi,

When using the Locks and Waits analysis, the tpsstool hooks the SetEvent API. During startup of our application not too much is happening in parallel and everything works. At some stage the application starts receiving and processing a lot of data in parallel (8 threads) and then the hook indirectly causes an access violation and the unhandled exception handler is called:

Hardware event construction

Eingereicht von Hanqing H. am

Sorry to ask a stupid question. We have a 4P Intel Xeon E5-4620 CPU (Sandy Bridge), and we want to use vtune to moniter some hardware events in the packege.  Our motherboard is Dell R720. So, where can we get the events that can be sampled with vtune-update5? I have seen a list in the last section of http://software.intel.com/sites/products/documentation/doclib/stdxe/2013...

Sandy Bridge Memory analysis problems

Eingereicht von rahul.garg am

Trying to use the analysis type "Memory access - Sandy Bridge and Ivy Bridge" in VTune 2013 on an application. App runs fine, and results are collected and processed but the application opens the viewpoint "Task Time". Task Time appears to be the wrong viewpoint for this analysis and thus it shows basically nothing useful. It does not allow me to switch the viewpoint to anything else either.

Any help here?

Setup:

Windows 7 x64, VTune Amplifier 2013 XE Update 4 (build 270817). CPU: 3610QM (quad-core ivy bridge).

Amplifier XE2013 Error 0x40000002 Insufficient memory Failed to finalize result

Eingereicht von Sonjuhi K. am

Hello experts,

I am evaluating Parallel Studio XE 2013 update 2 to see if this software could be useful for our software development needs. On most runs it crashes with message "Failed to finalize the result - Error 0x40000002 (Insufficient memory)". Here is what I see in the output window.

New experimental feature: Caller / Callee view!

Intel® VTune™ Amplifier XE 2013 Update 5 (released Feb. 26, 2013) includes a new experimental feature that can be enabled with an environment variable. 

An experimental feature is a beta quality feature that may or may not appear in a future production release.  We need feedback from users who try it on real code to tell us if we should keep it, change it or drop it.  Note: data collected with the experimental feature enabled is not guaranteed to be backward compatible with future releases. Please give this new feature a try, and tell us what you think!

VTune Profiler giving Error: “The Data Cannot be displayed,there is no viewpoint available for data ”

I want to optimize my code which is written in c++ on linux platform.For that i am using Intel VTune Performance Analyzer Profiler .When i am identifying Hotspots , then it gives Error: "The Data Cannot be displayed,there is no viewpoint available for data ".
