PMU counter in use but I cannot find vtune or aps processes.

vtune: Warning: EMON Collector Message: Warning: PMU counter(s) [GP0 GP1 GP2 GP3 GP4 GP5 GP6 GP7 FP0 ] is/are already in use by other software and the data collected on these counter(s) may be incorrect
vtune: Error: EMON Collector Message: ERROR - A collection is already in progress - Abort current run.
aps Error: Cannot run the collection.

When I analysis an application with aps and  the application fails to run, I get errors as shown above after restarting the application with aps again.

 

I didn't find any processes with words like 'aps' or 'vtune'.  Why are there still some processes that occupy PMU counters?

How should I reset the PMU counter or find processes that occupy PMU counters?

Hi,


We will check on this internally and let you know.

Any ideas?

 

At the present stage, we have to reboot to reset the counter to avoid occupation of unknown processes.

 

It's really time consuming....

Hi, you could check sep, emon or amplxe-perf processes too.

I checked all of them. There is no aps/perf/emon/sep-like processes.

 

More details:

When I killed my application, there are many processes `[aps] <defunct>` left. And I killed them all with `kill -9`. Will this be the reason?

I'm having exactly the same problem.  APS worked for many jobs, but suddenly all failed for similar error: 

 

>aps hostname 

vtune: Error: EMON Collector Message: ERROR - A collection is already in progress - Abort current run.

aps Error: Cannot run the collection. 

 

And I don't have any related process running at all. I run it on compute nodes of a big HPC, all the user processes got cleaned each time the job is finished.   

Any solution or trick to get around this?
