NUMA-MAPS (Display Memory Use)
NUMA-MAPS lets you display information about how your current processes are using memory on NUMA hardware, including files, stack, and heap (or subsets that you select). The parent of this subsection explains the meaning of NUMA hardware as well as the affinity and memory-policy issues that pertain to it.
To report on your NUMA memory use, type
Here processoption selects the process(es) to cover and can be any ONE of these mutually exclusive alternatives:
Likewise, scopeoption selects the granularity of the report (the default scope is mapped stack and heap memory only):
If you plan to pipe NUMA-MAPS output into another program for further processing you can omit the descriptive header by invoking the --no-header (-n) option along with any others. And root users will want to include --ignore-zero (-q) to skip processes (such as kernel threads) without any mapped pages.
