Hi Corey, Thank you. Your advice is very helpful to me. I will try again with the following environment.
1) Kernel 2.6.18 source tree including only perfmon patch linux-2.6.18-53.1.6.el5-x86_64.papi.tar.gz perfmon-new-base-060926.tar.gz No perfctr patch 2) pfmon-3.2 pfmon-3.2-060926.tar.gz 3) libpfm-3.2 libpfm-3.2-060926.tar.gz Regards, Satoshi Isono -----Original Message----- From: Corey J Ashford [mailto:cjash...@us.ibm.com] Sent: Tuesday, June 09, 2009 4:22 AM To: Satoshi Isono Cc: perfmon-ML; Pradeep Rao Subject: RE: [perfmon2] Precondition before installing Hello Satoshi, You cannot have both the perfctr and perfmon kernel patches at the same time. They both act in the same role: to provide access to the chip's PMU from user space. So you only need one of them. Perfctr is no longer being developed, and the newer of the two is perfmon. One other thing - this is somewhat confusing, but libpfm is a user-space library which can be used with perfctr or perfmon. libpfm wasn't designed to work exclusively with perfmon, though the same person (Stephane Eranian) wrote both libpfm and perfmon. I hope that clears things up a little. - Corey "Satoshi Isono" <is...@cray.com> wrote on 06/08/2009 07:43:44 AM: > Dear Pradeep, Corey, > > Thanks for your explanation.
