Hi Albert,<br><br>There can also be internal hardware conflicts with using too many memory counters in a single run. I often have to try out different sets of counters that can be counted together in a single run. <br><br>
Other performance tools on the system that can also access the PAPI counters include PerfSuite and TAU.<br><br>/disks/large/soft/tau-2.18<br>/disks/large/soft/perfsuite-0.6.2b3<br><br>I have not tried using PAPI directly, but that is of course another option. Let me know if you have any questions about using these tools.<br>

Hi Albert,<br>
<br>
Yes, we've been using PAPI quite extensively -- the most recent installed version is 3.6.2 and you can check whether the counters you are interested are supported by running<br>
<br>
/disks/soft/papi-3.6.2/bin/papi_avail<br>
<br>
and if there is an event that's not supported, it is most likely still available natively -- you can check those names with papi_native_avail.<br>

Subject: [Cookie-users] Using PAPI on Cookie<br>
<br>
Hi All,<br>
<br>
Has anybody successfully tried using PAPI on Cookie to perform hardware<br>
counting (e.g., cache hits/misses)? I tried it a couple months ago, but<br>
(if my memory is not mistaken) some low-level instructions are not<br>
supported by PAPI for the Xeon architecture, thus can't assess the cache<br>
behavior.<br>
<br>
Thanks,<br>
--Albert<br>
<br>
