Logging pipleline stalls with instruction info
Posted: Wed Feb 12, 2014 12:31 pmHi,
I am trying to use PAPI to leverage the information that it can collect. I am particularly interested to monitor "pipeline stall" event. However, my requirement is not just about counting the number of stalls for an execution. I am looking for more information per stall event i.e. the information about the instructions for which it stalls (e.g. instruction address). Is it possible to get this information using PAPI? if yes, I shall further appreciate for help on this. If no, then is there any other way to get this information?
thanking you
