-
|
||
|
|
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.
