Using vtune web interface on DevCloud, when I enable "Collect C-State events", I get the following error:
Thank you for posting in Intel Communities.
Could you please let us know
- The analysis type you are trying to run in Vtune.
- Vtune version
- A sample reproducer of the input.
- Additional settings(if any) to reproduce the issue
Note: Below are the available analysis types in VTune
As I said that problem exists on DevCloud. Now I am using my own Linux system and see the same error. So, let me explain what is my configuration.
I followed the steps here to change the ownership of /sys/kernel/debug/tracing
$ sudo chown -R mahmood:vtune /sys/kernel/debug/tracing $ sudo ls -l /sys/kernel/debug/ total 0 ... drwxr-xr-x 2 root root 0 Mar 14 13:09 sync drwx------ 8 mahmood vtune 0 Mar 14 13:09 tracing drwxr-xr-x 2 root root 0 Mar 14 13:09 ttm ... $ groups mahmood adm cdrom sudo dip plugdev lpadmin lxd sambashare libvirt vtune $ whoami mahmood
So, all are set.
But as you can see below, when I launch vtune and enable "Collect C-State events", I still get the same error.
I would like to test the matrix multiplication example and the CPU is Intel(R) Core(TM) i5-6600.
We are unable to reproduce the issue from our end. Could you please share with us the exact steps you have followed. Let us know how you enabled the collect c-state event.
Glad to know that your issue is resolved. If you need any additional information, please post a new question as this thread will no longer be monitored by Intel.
