HSW uncore

Postby qc7612 » Wed Apr 15, 2015 12:07 am


I was using PAPI 5.4.1 on WSM core and I can collect uncore performance counters. However, I cannot get uncore performance counters on HSW-EP machine (2 sockets, XEON CPU e5-2620 v3 @2.4Ghz).

For example, after I run "sudo ./all_native_events" under ctest directory, it didn't show any uncore performance counters. At the end, it gave the following messages:
Disabled: No uncore PMUs or events found

I am using Ubuntu 14 with linux kernel 3.13.0-49-generic.

I have two questions:
1) Are HSW-EP uncore performance counters supported in PAPI now?
2) If so, how could I enable uncore PMUs?

As Stephane mentioned on the perfmon2 mailing list, libpfm4 does not yet have HSW-EP uncore PMU support. He is working on it.
