I calc llcm. It's about 60%, when I run vasp.

I use the following formula

LONGEST_LAT_CACHE.MISS * 100  /  ( LONGEST_LAT_CACHE.MISS + MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HITM + MEM_LOAD_UOPS_LLC_HIT_RETIRED.XSNP_HIT )

I've no idea about if this is right.

Hi GHui,

longest latency cache miss rate should be LONGEST_LAT_CACHE.MISS/LONGEST_LAT_CACHE.REFERENCE 

Thanks,

Roman
