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
L1 instruction cache.
