Re: [PerfSuite-bugs] Issue with papi3_p4.xml

[Rick K. <rk...@nc...>]

Edwin,

Thank you for reporting this and also for the nice comment about
PerfSuite, I'm very glad you find it useful and took the time
to give it a try.  Any of this type of report or suggestions for
improvement are always welcome.

I agree with you that it is probably not a bug per se, but a
configuration file issue that should be corrected for future
releases.  I'm glad you were able to work it through without
much problem.

In general, the PAPI development team often updates their
event definitions to improve them and make sure they're counting
things as best as possible, and I bet this is what happened
for PAPI_L2_DCR on the P4, and PerfSuite got a bit behind on
what's the latest!

Thanks again,

Rick
