Intel PCM - Processor not supported

I am getting the following error for my processor. I provide the processor information also.

[ intelpcm]$ ./pcm.x 1

Hi,

Hi, this is expected. Your processor does not have the architecture that PCM requires. Thanks, Roman

Hi Roman,

Hi Roman, Thanks for the reply. Is there any other utility for measuring no. of instructions, cache misses per process like PCM and perf. regards, Rupinder

Did you try Linux perf

Did you try Linux perf already on your system?

i have linux kernal 2.6.18 on this machine .Perf is supported only by kernals higher than 2.6.31/32, if i am right.

The "perf events" subsystem

McCalpinJohn — Wed, 26 Sep 2012 15:04:36 GMT

The "perf events" subsystem was introduced in the 2.6.32 time frame. For 2.6.18 kernels you can try either the perfctr or perfmon2 patches. We use a slightly modified version of perfctr on our 2.6.18 production systems.

Have you try measuring the

Rupinder__V_ — Wed, 26 Sep 2012 15:19:39 GMT

Have you try measuring the counters per process (using PID as in the case of Perf stat command), e.g. tracking a java application (apache tomcat). Is there any way of doing such thing for java application?
