|
|
Memory read data volume [GBytes] = 1.0E-09*(MEM_ACCESS_RD)*64.0
|
||
|
|
Memory write bandwidth [MBytes/s] = 1.0E-06*(MEM_ACCESS_WR)*64.0/runtime
|
||
|
|
Memory write data volume [GBytes] = 1.0E-09*(MEM_ACCESS_WR)*64.0
|
||
|
|
Memory bandwidth [MBytes/s] = 1.0E-06*(MEM_ACCESS_RD+MEM_ACCESS_WR)*64.0/runtime
|
||
|
|
Memory data volume [GBytes] = 1.0E-09*(MEM_ACCESS_RD+MEM_ACCESS_WR)*64.0
