Formulas:
L3 read bandwidth [MBytes/s] = 1.0E-06*(L2D_CACHE_REFILL)*64.0/runtime
L3 read data volume [GBytes] = 1.0E-09*(L2D_CACHE_REFILL)*64.0
L3 write bandwidth [MBytes/s] = 1.0E-06*(L2D_CACHE_WB)*64.0/runtime
L3 write data volume [GBytes] = 1.0E-09*(L2D_CACHE_WB)*64.0
L3 bandwidth [MBytes/s] = 1.0E-06*(L2D_CACHE_REFILL+L2D_CACHE_WB)*64.0/runtime
L3 data volume [GBytes] = 1.0E-09*(L2D_CACHE_REFILL+L2D_CACHE_WB)*64.0
