Formulas:
L2D load bandwidth [MBytes/s] = 1.0E-06*L1D_REPL*64.0/time
L2D load data volume [GBytes] = 1.0E-09*L1D_REPL*64.0
L2D evict bandwidth [MBytes/s] = 1.0E-06*L1D_M_EVICT*64.0/time
L2D evict data volume [GBytes] = 1.0E-09*L1D_M_EVICT*64.0
L2 bandwidth [MBytes/s] = 1.0E-06*(L1D_REPL+L1D_M_EVICT+L1I_MISSES)*64/time
L2 data volume [GBytes] = 1.0E-09*(L1D_REPL+L1D_M_EVICT+L1I_MISSES)*64
-
Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the
number of cache line allocated in the L1 and the number of modified cache lines
evicted from the L1. Also reports on total data volume transferred between L2
and L1 cache. Note that this bandwidth also includes data transfers due to a
write allocate load on a store miss in L1 and traffic caused by misses in the
instruction cache.
