PAPI attach to child process

Postby ayazakram_89 » Mon Aug 17, 2015 7:23 pm

Hi everyone !!
I am interested in analyzing behavior of only particular interval (interval of instructions) of a benchmark. To do this I am attaching PAPI counters to child process (the benchmark) and continuously monitoring the counters from parent process, to know when the benchmark starts executing the instructions I am interested in. The problem with this approach is that sometimes the counters seem to stop updating. Will the counters not update properly if I am reading them continuously or with very minute delay?? Any insights ??
