The events of BR_INST_RETIRED.ANY can't be computed corretctly

191 Views

Hello, all.

According to the vtune manual, the number of events is computed by multiplying the number of samplesby Sample After value, right? If I set thesample interval to n, then the result shouldmultiplyn.

When I use this formula to verify the number of events, they are right except the event BR_INST_RETIRED.ANY.

Moreover, the number of event BR_INST_RETIRED.ANY is not stable during different run.Can anyone explain it to me ? Thanks.
