VTune does not work when analyze processor graphics hardware events

Lingzhi_S_ — Mon, 27 Oct 2014 18:20:09 GMT

Hi everyone,

My VTune 2015 doesn't work when I choose "Overview" at "Analyze Processor Graphics Hardware Events". (work fine when choose "None". ) The log shows "The result you are opening is empty. This may be caused by an error during data collection. Try to re-run the analysis.", but also "Data collection is completed successfully." And the command window shows nothing like the application doesn't work successfully.

I use: windows 8.1 pro, vtune 2015, i7 4800mq

thx

Did you select "Analyze user tasks" and "Analyze GPU Usage" checkboxes?

Please provide screenshots of your settings. The above settings worked for me.

Hi Lingzhi,

I successfully ran my workload with your settings. My workload can be downloaded here: https://software.intel.com/sites/default/files/managed/87/66/Sobel_OCL.zip (my article describing the workload could be found here: https://software.intel.com/en-us/INDE-OpenCL-Sobel)

If you are unable to analyze my workload, I suggest that you try to submit your question directly to Intel Vtune Amplifier XE forum:

https://software.intel.com/en-us/forums/intel-vtune-amplifier-xe ;

If you are able to analyze my workload, try to examine your project more carefully. If you thing everything is OK with your project, Vtune forum above should be a better place to solve your problem.

It still doesn't work..
