Profiling group to measure the traffic from local CPU to the different
|
||
|
|
DRAM NUMA nodes. This group allows to detect NUMA problems in a threaded
|
||
|
|
code. You must first determine on which memory domains your code is running.
|
||
|
|
A code should only have significant traffic to its own memory domain.
