So any particular CPU has some\nmemory in each zone structure which belongs to itself. Even if that CPU is\nnot local to that zone.\n\nSo the patch relocates the pagesets for each cpu to the node that is nearest\nto the cpu instead of allocating the pagesets in the (possibly remote) target\nzone. This means that the operations to manage pages on remote zone can be\ndone with information available locally.\n\nWe play a macro trick so that non-NUMA pmachines avoid the additional\npointer chase on the page allocator fastpath.\n\nAIM7 benchmark on a 32 CPU SGI Altix\n\nw/o patches:\nTasks jobs/min jti jobs/min/task real cpu\n 1 484.68 100 484.6769 12.01 1.97 Fri Mar 25 11:01:42 2005\n 100 27140.46 89 271.4046 21.44 148.71 Fri Mar 25 11:02:04 2005\n 200 30792.02 82 153.9601 37.80 296.72 Fri Mar 25 11:02:42 2005\n 300 32209.27 81 107.3642 54.21 451.34 Fri Mar 25 11:03:37 2005\n 400 34962.83 78 87.4071 66.59 588.97 Fri Mar 25 11:04:44 2005\n 500 31676.92 75 63.3538 91.87 742.71 Fri Mar 25 11:06:16 2005\n 600 36032.69 73 60.0545 96.91 885.44 Fri Mar 25 11:07:54 2005\n 700 35540.43 77 50.7720 114.63 1024.28 Fri Mar 25 11:09:49 2005\n 800 33906.70 74 42.3834 137.32 1181.65 Fri Mar 25 11:12:06 2005\n 900 34120.67 73 37.9119 153.51 1325.26 Fri Mar 25 11:14:41 2005\n 1000 34802.37 74 34.8024 167.23 1465.26 Fri Mar 25 11:17:28 2005\n\nwith slab API changes and pageset patch:\n\nTasks jobs/min jti jobs/min/task real cpu\n 1 485.00 100 485.0000 12.00 1.96 Fri Mar 25 11:46:18 2005\n 100 28000.96 89 280.0096 20.79 150.45 Fri Mar 25 11:46:39 2005\n 200 32285.80 79 161.4290 36.05 293.37 Fri Mar 25 11:47:16 2005\n 300 40424.15 84 134.7472 43.19 438.42 Fri Mar 25 11:47:59 2005\n 400 39155.01 79 97.8875 59.46 590.05 Fri Mar 25 11:48:59 2005\n 500 37881.25 82 75.7625 76.82 730.19 Fri Mar 25 11:50:16 2005\n 600 39083.14 78 65.1386 89.35 872.79 Fri Mar 25 11:51:46 2005\n 700 38627.83 77 55.1826 105.47 1022.46 Fri Mar 25 11:53:32 2005\n 800 39631.94 78 49.5399 117.48 1169.94 Fri Mar 25 11:55:30 2005\n 900 36903.70 79 41.0041 141.94 1310.78 Fri Mar 25 11:57:53 2005\n 1000 36201.23 77 36.2012 160.77 1458.31 Fri Mar 25 12:00:34 2005\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Shobhit Dayal \u003cshobhit@calsoftinc.com\u003e\nSigned-off-by: Shai Fultheim \u003cShai@Scalex86.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "01424961e621737c638e489b6a0b5e6602b02612", "tree": "ae51380febe42e40d09375648b0d379325b905a7", "parents": [ "bc86120a85ebf553180946e8854d1993f074e9f5" ], "author": { "name": "Al Viro", "email": "viro@www.linux.org.uk", "time": "Sun Apr 24 12:28:34 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sun Apr 24 12:28:34 2005 -0700" }, "message": "[PATCH] mempolicy.c GFP fix\n\nzonelist_policy() forgot to mask non-zone bits from gfp when comparing\nzone number with policy_zone. \n\nACKed-by: Andi Kleen \u003cak@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@parcelfarce.linux.theplanet.co.uk\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "tree": "0bba044c4ce775e45a88a51686b5d9f90697ea9d", "parents": [], "author": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@ppc970.osdl.org", "time": "Sat Apr 16 15:20:36 2005 -0700" }, "message": "Linux-2.6.12-rc2\n\nInitial git repository build.
