Formulas:
Memory read bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC0))*64.0/runtime
Memory read data volume [GBytes] = 1.0E-09*(SUM(MBOXxC0))*64.0
Memory write bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC1))*64.0/runtime
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/runtime
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. Some of the counters may not be available on your system.
Also outputs total data volume transferred from main memory.
The same metrics are provided by the HA group.
