• The number of events that can be collected at a time is restricted by the number of hardware PMCs available on a platform. AMDuProfSys divides the list of events into groups, with each group consisting of a maximum of PMC-count number of events. These events groups are multiplexed during a run. Due to this, sampling may not provide 100% accurate data, especially if the profiling has run for very little time.
