[PerfSuite-users] Re: PerfSuite problem - multiplexing not working?

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

Kursad,

Thanks for the update on how things are going.  It sounds like you're
making some progress, I hope the comments were helpful.  I'd like
to make sure I'm understanding your experience because as you know,
PerfSuite is still in a beta release.  It would be nice to adjust
things/problems before going final later this year.

So to recap: you are saying that PIII configs that do not include
derived events work for you, is that right?  It seems to me that
if counter resources are not available, that psrun shouldn't even
write out an XML document, but instead report an error.  Does that
seem like more reasonable behavior?

P4 - same thing?

If you could send me an example config that shows this behavior,
it would help me test/verify here on our systems.

The Perl script idea sounds good: there's no Perl anything currently
in the PerfSuite distribution but if you develop a post-processor
that might be interesting to others, I'd love to hear of it.

Also - if you're finding there are particular metrics you're using
frequently, you may be able to add them to the default calculations
that psprocess does by adding them into its "database".  That's
an XML document that gets installed here:

  $PREFIX/share/perfsuite/xml/pshpwc/PAPI_metrics.xml

Thanks again for the update,

Rick
