Hello, I have the following problem while trying to gather hardware counters on Barcelona: whenever I start several programs with the same counter profiling on AMD Barcelona, all of the program invocations except the first failing with conflicting monitoring session error. The problem can be revealed with smth like that:
$ pfmon --events=MEMORY_CONTROLLER_REQUESTS:READ_REQUESTS sleep 20 & [1] $ pfmon --events=MEMORY_CONTROLLER_REQUESTS:READ_REQUESTS sleep 20 & error conflicting monitoring session exists There is no such behaviour on Intel Xeon processors. I wonder what may cause this strange problem and are there any workarounds to it (i.e. is it still possible to gather same counter info for several programs/threads at the same time)?
