+Supported numa-policies:

+.TP
|
||||||
|
+.B interleave
|
||||||
|
+Memory will be allocated using round robin on nodes. When
|
||||||
|
+memory cannot be allocated on the current interleave, target fall back
|
||||||
|
+to other nodes. Multiple nodes may be specified.
|
||||||
|
+.TP
|
||||||
|
+.B membind
|
||||||
|
+Only allocate memory from nodes. Allocation will fail
|
||||||
|
+when there is not enough memory available on these nodes. Multiple
|
||||||
|
+nodes may be specified.
|
||||||
|
+.TP
|
||||||
|
+.B preferred
|
||||||
|
+Preferably allocate memory on node, but if memory cannot be
|
||||||
|
+allocated there fall back to other nodes. This option takes only a
|
||||||
|
+single node number.
|
||||||
|
+.TP
|
||||||
|
+.B default
|
||||||
|
+Memory will be allocated on the local node (the node the
|
||||||
|
+thread is running on)

Subject: [PATCH] numastat.8: clarify that information relates to resident
|
||||||
|
pages
|
||||||
|
|
||||||
|
The man page gives no hint about whether memory usage information
|
||||||
|
relates to resident pages or virtual memory. The answer may not be
|
||||||
|
obvious to the user, so explicitly mention that only resident pages are
|
||||||
|
counted.
