PAPI_LD_INS gives uops count instead of instructions count

Postby gany47 » Thu Sep 26, 2013 12:28 am

HI all,

I have been using PAPI 5.0.1 version and I am having some issues with PAPI_LD_INS & PAPI_SR_INS. These papi events are being mapped to the uops retired on my system (MEM_UOP_RETIRED:ANY_LOADS, MEM_UOP_RETIRED:ANY_STORES) and so I am not able to compare them against the PAPI_TOT_INS which gives the actual retired instructions. Is there any way I can get the actual load/store instructions count rather than the operations count?

$ papi_avail -e PAPI_LD_INS
