Interpreting hpcpilist Event Counts

The value of the instruction pointer recorded is typically several or many instructions after the
instruction that caused the event. This lag or skid is common to all profilers that sample instruction
pointers and HPCPI does not attempt to model the system to correct for this. As a result, HP
recommends that you examine the assembly code surrounding regions where high event counts
occur and consider if the surrounding code might be triggering the events. For more information,
see

“HPCPI Product Limitations” (page 115)
