Linux: Compacting Memory Jun 3, 2007, 20 :00 UTC (0 Talkback[s]) (6373 reads)
"Mel Gorman offered a first release of a patchset that compacts memory, 'this is a prototype for compacting memory to reduce external fragmentation so that free memory exists as fewer, but larger contiguous blocks. Rather than being a full defragmentation solution, this focuses exclusively on pages that are movable via the page migration mechanism.' He notes that the patchset is currently incomplete, and at this time memory is only compacted manually, not automatically, 'this version of the patchset is mainly concerned with getting the compaction mechanism correct...'"
