I am running Amplifier cluster edition 2016 on Intel(R) Xeon(R) CPU E7-2890 v2 @ 2.80GHz, Linux.
After I killed a previous session of the amplxe-cl application, any attempt yo start an analysis either using "amplxe-gui" or "amplxe-cl" fails with the following error message: PMU resource(s) currently being used by another profiling tool or process: another PMU collection session may be running.
Even after killing any leftover processes that looked like amplxe, the error does not go away. How can I ensure no instance of amplxe is running?
Based on your error message, ensure that you have no other tool which is using PMU resource. See below in release notes:
Running other PMU-based tools simultaneously with hardware event-based sampling
collection is not supported (200166101)
o The Sampling Driver requires exclusive use of the PMU resources. Running multiple PMU
based tools will cause incorrect results and/or system instability.
You can refer to other thread - which had similar issue, running on MPI program?
You can try:
If it does not help - please re-load the driver: under administrative privileges run:
><VTune_install_dir>/sepdk/src/insmod-sep -g <vtune_group>
Thanks & Regards, Dmitry
