migratepages

MIGRATEPAGES(8) 					   Linux Administrator's Manual 					   MIGRATEPAGES(8)

NAME

       migratepages - Migrate the physical location a processes pages

SYNOPSIS

       migratepages pid from-nodes to-nodes

DESCRIPTION

       migratepages  moves  the physical location of a processes pages without any changes of the virtual address space of the process. Moving the
       pages allows one to change the distances of a process to its memory. Performance may be optimized by moving a processes pages to  the  node
       where it is executing.

       If  multiple  nodes are specified for from-nodes or to-nodes then an attempt is made to preserve the relative location of each page in each
       nodeset.

       For example if we move from nodes 2-5 to 7,9,12-13 then the preferred mode of operation is to move pages from 2->7, 3->9, 4->12 and  5->13.
       However, this is only posssible if enough memory is available.

       Valid node specifiers

	      all		  All nodes
	      number		  Node number
	      number1{,number2}   Node number1 and Node number2
	      number1-number2	  Nodes from number1 to number2
	      ! nodes		  Invert selection of the following specification.

NOTES

       Requires an NUMA policy aware kernel with support for page migration (linux 2.6.16 and later).

       migratepages will only move pages that are not shared with other processes if called by a user without administrative priviledges (but with
       the right to modify the process).

       migratepages will move all pages if invoked from root (or a user with administrative priviledges).

FILES

       /proc/<pid>/numa_maps for information about the NUMA memory use of a process.
