|
|
L2D load bandwidth [MBytes/s] = 1.0E-06*REQUESTS_TO_L2_GRP1_ALL_NO_PF*64.0/time
|
||
|
|
L2D load data volume [GBytes] = 1.0E-09*REQUESTS_TO_L2_GRP1_ALL_NO_PF*64.0
|
||
|
|
L2 bandwidth [MBytes/s] = 1.0E-06*(REQUESTS_TO_L2_GRP1_ALL_NO_PF)*64/time
|
||
|
|
L2 data volume [GBytes] = 1.0E-09*(REQUESTS_TO_L2_GRP1_ALL_NO_PF)*64
