Hi, Thanks for the reply. To get the version of the perfmon tool, I used pfm_get_version() and got the following information:
version: 196616 PFMLIB_MAJ_VERSION=3 PFMLIB_MIN_VERSION= 8 The kernel version is: Linux 2.6.25 Actually I can read the counters normally and now am trying to read those in a thread using pthreads. I found one document that mentions that the context should be attached to a thread and that thread must be pinned to a particular core. I am trying to that, but it is showing me the same error message as follows: pfm_load_context error errno 1 pfm_start error errno 22 pfm_stop error errno 22 I have also tried the pfm_strerr() function to know the error name, but it shows the following message. Error name: unknown error code Can you please help? Thanks Tanima. ________________________________ From: stephane eranian <eran...@googlemail.com> To: Tanima Dey <dey_tr...@yahoo.com> Cc: perfmon2-devel@lists.sourceforge.net Sent: Wednesday, July 1, 2009 1:09:13 AM Subject: Re: [perfmon2] Error no Hi, On Sat, Jun 27, 2009 at 5:03 PM, Tanima Dey<dey_tr...@yahoo.com> wrote: > Hi, > > I am a very new user of perfmon.
