Hi:

I'm running on Fedora17 on an Ivy Bridge.  When I downloaded PCM, built it and tried to run it, I get the following error.

Any thoughts?

Joe, PCM memory bandwidth metrics (displayed in the pcm-memory utility) are not supported for Intel(R) Core(TM) i7-3770 processor. We are looking into ways how it can be supported in PCM in future if possible. However, many other processor metrics are still supported and can be already displayed with pcm.x utility. Best regards, Roman

Thanks Roman for the quick reply. I'll stay with pcm.x for now. Joe

I'm also not seeing memory bandwidth metrics on Core i7-2860QM and Core i7-3517U.  Are these also not supported?  Is there a list of the supported metrics for each of the chips?

Hi cqegbert@gmail.com,

The recent Intel PCM 2.4 should support memory bandwidth monitoring on 2nd and 3rd generation Intel® Core™ processors (including Intel(r) Core(tm) i7-2860QM, Core(tm) i7-3517U, Core(TM) i7-3770) with Linux pcm.x utility.

Thanks,

Roman

Linux only?  No Windows?

Hi,

Intel PCM V2.8 now supports memory bandwidth metrics on your processor also in Windows (via winpmem driver).

Best regards,

Roman
