VTune not launching application Ubuntu 16.04

Hello, 

When I try to launch my binary with vtune for hotspots analysis, it successfully "collects data" but does not actually launch the application. The summary shows zero calls and zero threads launched. 

I followed all the instructions to set up vtune from here: https://software.intel.com/en-us/vtune-install-guide-linux (I am on Ubuntu 16.04)

I know that my application runs from the terminal. When I pass the exact same application into the "Application" field and the same parameters into the "Application parameters" field. I encounter no errors; the application simply does not run. Nothing appears in the terminal from which I launched vtune-gui.

Any ideas on how to fix this?

Hi,

Thanks for reaching out.

Could you please mention the application type(cpp/Python) and the type of sampling used(User-Mode/Hardware Event-Based).

Hello, using the hardware sampling option instead of user-generated allowed the program to complete.

Hi,

Thanks for the update.

Are you ok with the results of harware based sampling?

The CPU hotspots analysis report is good.

However, the memory consumption analysis does not work. I get Error 0x40000024 (No data). There is no "hardware sample" option for the Memory hotspots analysis to fix this.

I am using VTune Profiler 2020 to run a binary that I am developing. The binary runs flawlessly from command line, but fails to execute in VTune. When I set it up with the same parameters, I get this error:

"VTune Profiler 2020 has face a serious problem

Cannot open data: ...

Error 0x40000024 (No data) ..."

Please see attached screenshot. I am using 32-byte minimum object memory size (default).

Hi,

Could you please try Memory-access Command Line Analysis.

Please find the below command:

vtune -collect memory-access -knob analyze-mem-objects=true -knob dram-bandwidth-limits=true -- home/test/myApplication

When the data collection is complete, do one of the following to view the result:

  • Use the -report action to view the data from command line.
  • Use the -report-output action to write report to a .txt or .csv file

Hope this helps. Please let us know if you face any issues.

Thanks

Hello, the solution did not work sadly. It also ends the collection immediately after starting and does not produce any useful results.

It seems like there's a problem instrumenting the application. Have you tried running VTune as root?
