Memory read bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC0))*64.0/time
|
|
Memory read data volume [GBytes] = 1.0E-09*(SUM(MBOXxC0))*64.0
|
|
Memory write bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC1))*64.0/time
|
|
Memory write data volume [GBytes] = 1.0E-09*(SUM(MBOXxC1))*64.0
|
|
Memory bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC0)+SUM(MBOXxC1))*64.0/time
|
|
Memory data volume [GBytes] = 1.0E-09*(SUM(MBOXxC0)+SUM(MBOXxC1))*64.0

-
|
|
Profiling group to measure memory bandwidth drawn by all cores of a socket.
|
|
Since this group is based on Uncore events it is only possible to measure on a
|
|
per socket base. Also outputs total data volume transferred from main memory.
