SHORT L2 cache bandwidth in MBytes/s EVENTSET PMC0 DATA_CACHE_REFILLS_ALL PMC1 DATA_CACHE_REFILLS_SYSTEM PMC2 CPU_CLOCKS_UNHALTED METRICS Runtime (RDTSC) [s] time L2 bandwidth [MBytes/s] 1.0E-06*(PMC0-PMC1)*64.0/time L2 data volume [GBytes] 1.0E-09*(PMC0-PMC1)*64.0 Cache refill bandwidth System/L2 [MBytes/s] 1.0E-06*PMC0*64.0/time Cache refill bandwidth System [MBytes/s] 1.0E-06*PMC1*64.0/time LONG Formulas: L2 bandwidth [MBytes/s] = 1.0E-06*(DATA_CACHE_REFILLS_ALL-DATA_CACHE_REFILLS_SYSTEM)*64/time L2 data volume [GBytes] = 1.0E-09*(DATA_CACHE_REFILLS_ALL-DATA_CACHE_REFILLS_SYSTEM)*64 Cache refill bandwidth system/L2 [MBytes/s] = 1.0E-06*DATA_CACHE_REFILLS_ALL*64/time Cache refill bandwidth system [MBytes/s] = 1.0E-06*DATA_CACHE_REFILLS_SYSTEM*64/time - Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the number of cache line loaded from L2 to L1 and the number of modified cache lines evicted from the L1. Note that this bandwidth also included data transfers due to a write allocate load on a store miss in L1 and copy back transfers if originated from L2. L2-L2 data volume is the total data volume transferred between L2 and L1.
