My brother just sent me this inquiry and I thought I would ask here to see if any of you lot know anything about this before I send him a reply. Just checking whether you know anything about the various packages I could use to monitor performance of code running on X86 processors. I want to measure things like: - instructions executed, in a block of code (ie., from here to there) - cache misses (i-cache, d-cache, L1, L2, etc) - processor cycles - SSE4 instructions executed - ... and so on. There appear to be at least a few packages which expose the MSR functionality in varioius ways (e.g., the perfctr package). I wondered if you knew which package would be considered the 'best'. One unpleasant aspect of the perfctr package is that it appears that I need to apply patches to the kernel, then rebuild; this would appear to increase the complexity of system maintenance (can't just update and have everything up). -- MELVILLE THEATRE ~ Melville Sask ~ http://www.melvilletheatre.com -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
