Intel PCM - Processor not supported

[Rupinder__V_]

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

[ intelpcm]$ ./pcm.x 1

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

[Rupinder__V_]

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

[Roman_D_Intel]

Did you try Linux perf already on your system?

[Rupinder__V_]

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.

[McCalpinJohn]

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.

[Rupinder__V_]

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?
