I am trying to collect cache performance statistics with PAPI 4.1.0. It is an Intel Core i7 (Nehalem) processor. The OS is linux 2.6.31 Ubuntu 9.10 with perfctr 2.6.x installed.
When I run the test program using "make test" I got an error "pfm_initialize(): not supported" followed by "pfmlib not initialized." I checked the functionality perfctr by running programs in the "./example" directory like "perfex" and they all look good. Is there any thing I have missed?
I am kind of new on this, so sorry if somebody has justified before. I really appreciate any advice you could give me.
