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