Profiling group to measure NUMA traffic. The data sources range from
|
|
local L2, CCX and memory for the local metrics and remote CCX and memory
|
|
for the remote metrics. There are also events that measure the software
|
|
prefetches from local and remote domain but AMD Zen provides only 4 counters.
