      "message": "[PATCH] ZVC/zone_reclaim: Leave 1% of unmapped pagecache pages for file I/O\n\nIt turns out that it is advantageous to leave a small portion of unmapped file\nbacked pages if all of a zone\u0027s pages (or almost all pages) are allocated and\nso the page allocator has to go off-node.\n\nThis allows recently used file I/O buffers to stay on the node and\nreduces the times that zone reclaim is invoked if file I/O occurs\nwhen we run out of memory in a zone.\n\nThe problem is that zone reclaim runs too frequently when the page cache is\nused for file I/O (read write and therefore unmapped pages!) alone and we have\nalmost all pages of the zone allocated.  Zone reclaim may remove 32 unmapped\npages.  File I/O will use these pages for the next read/write requests and the\nunmapped pages increase.  After the zone has filled up again zone reclaim will\nremove it again after only 32 pages.  This cycle is too inefficient and there\nare potentially too many zone reclaim cycles.\n\nWith the 1% boundary we may still remove all unmapped pages for file I/O in\nzone reclaim pass.  However.  it will take a large number of read and writes\nto get back to 1% again where we trigger zone reclaim again.\n\nThe zone reclaim 2.6.16/17 does not show this behavior because we have a 30\nsecond timeout.\n\n[akpm@osdl.org: rename the /proc file and the variable]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] Light weight event counters\n\nThe remaining counters in page_state after the zoned VM counter patches\nhave been applied are all just for show in /proc/vmstat.  They have no\nessential function for the VM.\n\nWe use a simple increment of per cpu variables.  In order to avoid the most\nsevere races we disable preempt.  Preempt does not prevent the race between\nan increment and an interrupt handler incrementing the same statistics\ncounter.  However, that race is exceedingly rare, we may only loose one\nincrement or so and there is no requirement (at least not in kernel) that\nthe vm event counters have to be accurate.\n\nIn the non preempt case this results in a simple increment for each\ncounter.  For many architectures this will be reduced by the compiler to a\nsingle instruction.  This single instruction is atomic for i386 and x86_64.\n And therefore even the rare race condition in an interrupt is avoided for\nboth architectures in most cases.\n\nThe patchset also adds an off switch for embedded systems that allows a\nbuilding of linux kernels without these counters.\n\nThe implementation of these counters is through inline code that hopefully\nresults in only a single instruction increment instruction being emitted\n(i386, x86_64) or in the increment being hidden though instruction\nconcurrency (EPIC architectures such as ia64 can get that done).\n\nBenefits:\n- VM event counter operations usually reduce to a single inline instruction\n  on i386 and x86_64.\n- No interrupt disable, only preempt disable for the preempt case.\n  Preempt disable can also be avoided by moving the counter into a spinlock.\n- Handling is similar to zoned VM counters.\n- Simple and easily extendable.\n- Can be omitted to reduce memory use for embedded use.\n\nReferences:\n\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113512330605497\u0026w\u003d2\nRFC http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114988082814934\u0026w\u003d2\nlocal_t http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114991748606690\u0026w\u003d2\nV2 http://marc.theaimsgroup.com/?t\u003d115014808400007\u0026r\u003d1\u0026w\u003d2\nV3 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115024767022346\u0026w\u003d2\nV4 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115047968808926\u0026w\u003d2\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] zoned vm counters: basic ZVC (zoned vm counter) implementation\n\nPer zone counter infrastructure\n\nThe counters that we currently have for the VM are split per processor.  The\nprocessor however has not much to do with the zone these pages belong to.  We\ncannot tell f.e.  how many ZONE_DMA pages are dirty.\n\nSo we are blind to potentially inbalances in the usage of memory in various\nzones.  F.e.  in a NUMA system we cannot tell how many pages are dirty on a\nparticular node.  If we knew then we could put measures into the VM to balance\nthe use of memory between different zones and different nodes in a NUMA\nsystem.  For example it would be possible to limit the dirty pages per node so\nthat fast local memory is kept available even if a process is dirtying huge\namounts of pages.\n\nAnother example is zone reclaim.  We do not know how many unmapped pages exist\nper zone.  So we just have to try to reclaim.  If it is not working then we\npause and try again later.  It would be better if we knew when it makes sense\nto reclaim unmapped pages from a zone.  This patchset allows the determination\nof the number of unmapped pages per zone.  We can remove the zone reclaim\ninterval with the counters introduced here.\n\nFuthermore the ability to have various usage statistics available will allow\nthe development of new NUMA balancing algorithms that may be able to improve\nthe decision making in the scheduler of when to move a process to another node\nand hopefully will also enable automatic page migration through a user space\nprogram that can analyse the memory load distribution and then rebalance\nmemory use in order to increase performance.\n\nThe counter framework here implements differential counters for each processor\nin struct zone.  The differential counters are consolidated when a threshold\nis exceeded (like done in the current implementation for nr_pageache), when\nslab reaping occurs or when a consolidation function is called.\n\nConsolidation uses atomic operations and accumulates counters per zone in the\nzone structure and also globally in the vm_stat array.  VM functions can\naccess the counts by simply indexing a global or zone specific array.\n\nThe arrangement of counters in an array also simplifies processing when output\nhas to be generated for /proc/*.\n\nCounters can be updated by calling inc/dec_zone_page_state or\n_inc/dec_zone_page_state analogous to *_page_state.  The second group of\nfunctions can be called if it is known that interrupts are disabled.\n\nSpecial optimized increment and decrement functions are provided.  These can\navoid certain checks and use increment or decrement instructions that an\narchitecture may provide.\n\nWe also add a new CONFIG_DMA_IS_NORMAL that signifies that an architecture can\ndo DMA to all memory and therefore ZONE_NORMAL will not be populated.  This is\nonly currently set for IA64 SGI SN2 and currently only affects\nnode_page_state().  In the best case node_page_state can be reduced to\nretrieving a single counter for the one zone on the node.\n\n[akpm@osdl.org: cleanups]\n[akpm@osdl.org: export vm_stat[] for filesystems]\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] zoned vm counters: create vmstat.c/.h from page_alloc.c/.h\n\nNOTE: ZVC are *not* the lightweight event counters.  ZVCs are reliable whereas\nevent counters do not need to be.\n\nZone based VM statistics are necessary to be able to determine what the state\nof memory in one zone is.  In a NUMA system this can be helpful for local\nreclaim and other memory optimizations that may be able to shift VM load in\norder to get more balanced memory use.\n\nIt is also useful to know how the computing load affects the memory\nallocations on various zones.  This patchset allows the retrieval of that data\nfrom userspace.\n\nThe patchset introduces a framework for counters that is a cross between the\nexisting page_stats --which are simply global counters split per cpu-- and the\napproach of deferred incremental updates implemented for nr_pagecache.\n\nSmall per cpu 8 bit counters are added to struct zone.  If the counter exceeds\ncertain thresholds then the counters are accumulated in an array of\natomic_long in the zone and in a global array that sums up all zone values.\nThe small 8 bit counters are next to the per cpu page pointers and so they\nwill be in high in the cpu cache when pages are allocated and freed.\n\nAccess to VM counter information for a zone and for the whole machine is then\npossible by simply indexing an array (Thanks to Nick Piggin for pointing out\nthat approach).  The access to the total number of pages of various types does\nno longer require the summing up of all per cpu counters.\n\nBenefits of this patchset right now:\n\n- Ability for UP and SMP configuration to determine how memory\n  is balanced between the DMA, NORMAL and HIGHMEM zones.\n\n- loops over all processors are avoided in writeback and\n  reclaim paths. We can avoid caching the writeback information\n  because the needed information is directly accessible.\n\n- Special handling for nr_pagecache removed.\n\n- zone_reclaim_interval vanishes since VM stats can now determine\n  when it is worth to do local reclaim.\n\n- Fast inline per node page state determination.\n\n- Accurate counters in /sys/devices/system/node/node*/meminfo. Current\n  counters are counting simply which processor allocated a page somewhere\n  and guestimate based on that. So the counters were not useful to show\n  the actual distribution of page use on a specific zone.\n\n- The swap_prefetch patch requires per node statistics in order to\n  figure out when processors of a node can prefetch. This patch provides\n  some of the needed numbers.\n\n- Detailed VM counters available in more /proc and /sys status files.\n\nReferences to earlier discussions:\nV1 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d113511649910826\u0026w\u003d2\nV2 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d114980851924230\u0026w\u003d2\nV3 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115014697910351\u0026w\u003d2\nV4 http://marc.theaimsgroup.com/?l\u003dlinux-kernel\u0026m\u003d115024767318740\u0026w\u003d2\n\nPerformance tests with AIM7 did not show any regressions.

      "message": "[PATCH] overcommit: add calculate_totalreserve_pages()\n\nThese patches are an enhancement of OVERCOMMIT_GUESS algorithm in\n__vm_enough_memory().\n\n- why the kernel needed patching\n\n  When the kernel can\u0027t allocate anonymous pages in practice, currnet\n  OVERCOMMIT_GUESS could return success. This implementation might be\n  the cause of oom kill in memory pressure situation.\n\n  If the Linux runs with page reservation features like\n  /proc/sys/vm/lowmem_reserve_ratio and without swap region, I think\n  the oom kill occurs easily.\n\n- the overall design approach in the patch\n\n  When the OVERCOMMET_GUESS algorithm calculates number of free pages,\n  the reserved free pages are regarded as non-free pages.\n\n  This change helps to avoid the pitfall that the number of free pages\n  become less than the number which the kernel tries to keep free.\n\n- testing results\n\n  I tested the patches using my test kernel module.\n\n  If the patches aren\u0027t applied to the kernel, __vm_enough_memory()\n  returns success in the situation but autual page allocation is\n  failed.\n\n  On the other hand, if the patches are applied to the kernel, memory\n  allocation failure is avoided since __vm_enough_memory() returns\n  failure in the situation.\n\n  I checked that on i386 SMP 16GB memory machine. I haven\u0027t tested on\n  nommu environment currently.\n\nThis patch adds totalreserve_pages for __vm_enough_memory().\n\nCalculate_totalreserve_pages() checks maximum lowmem_reserve pages and\npages_high in each zone. Finally, the function stores the sum of each\nzone to totalreserve_pages.\n\nThe totalreserve_pages is calculated when the VM is initilized.\nAnd the variable is updated when /proc/sys/vm/lowmem_reserve_raito\nor /proc/sys/vm/min_free_kbytes are changed.\n\nSigned-off-by: Hideo Aoki \u003chaoki@redhat.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] slab: Node rotor for freeing alien caches and remote per cpu pages.\n\nThe cache reaper currently tries to free all alien caches and all remote\nper cpu pages in each pass of cache_reap.  For a machines with large number\nof nodes (such as Altix) this may lead to sporadic delays of around ~10ms.\nInterrupts are disabled while reclaiming creating unacceptable delays.\n\nThis patch changes that behavior by adding a per cpu reap_node variable.\nInstead of attempting to free all caches, we free only one alien cache and\nthe per cpu pages from one remote node.  That reduces the time spend in\ncache_reap.  However, doing so will lengthen the time it takes to\ncompletely drain all remote per cpu pagesets and all alien caches.  The\ntime needed will grow with the number of nodes in the system.  All caches\nare drained when they overflow their respective capacity.  So the drawback\nhere is only that a bit of memory may be wasted for awhile longer.\n\nDetails:\n\n1. Rename drain_remote_pages to drain_node_pages to allow the specification\n   of the node to drain of pcp pages.\n\n2. Add additional functions init_reap_node, next_reap_node for NUMA\n   that manage a per cpu reap_node counter.\n\n3. Add a reap_alien function that reaps only from the current reap_node.\n\nFor us this seems to be a critical issue.  Holdoffs of an average of ~7ms\ncause some HPC benchmarks to slow down significantly.  F.e.  NAS parallel\nslows down dramatically.  NAS parallel has a 12-16 seconds runtime w/o rotor\ncompared to 5.8 secs with the rotor patches.  It gets down to 5.05 secs with\nthe additional interrupt holdoff reductions.\n\nSigned-off-by: Christoph Lameter \u003cclameter@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

For example,\nnot many people know that: on 50% of i386 -Os builds, the first tail page of a\ncompound page purports to be PageAnon (when its destructor has an odd\naddress), which surprises page_add_file_rmap.\n\nKeep the compound page destructor in page[1].lru.next instead.

      "message": "[PATCH] Zone reclaim: Reclaim logic\n\nSome bits for zone reclaim exists in 2.6.15 but they are not usable.  This\npatch fixes them up, removes unused code and makes zone reclaim usable.\n\nZone reclaim allows the reclaiming of pages from a zone if the number of\nfree pages falls below the watermarks even if other zones still have enough\npages available.  Zone reclaim is of particular importance for NUMA\nmachines.  It can be more beneficial to reclaim a page than taking the\nperformance penalties that come with allocating a page on a remote zone.\n\nZone reclaim is enabled if the maximum distance to another node is higher\nthan RECLAIM_DISTANCE, which may be defined by an arch.  By default\nRECLAIM_DISTANCE is 20.  20 is the distance to another node in the same\ncomponent (enclosure or motherboard) on IA64.  The meaning of the NUMA\ndistance information seems to vary by arch.\n\nIf zone reclaim is not successful then no further reclaim attempts will\noccur for a certain time period (ZONE_RECLAIM_INTERVAL).\n\nThis patch was discussed before.

It\u0027s up to the batch\nmanager or other user code to decide what to do about it and take action.\n\n\u003d\u003d\u003e Unless this feature is enabled by writing \"1\" to the special file\n    /dev/cpuset/memory_pressure_enabled, the hook in the rebalance\n    code of __alloc_pages() for this metric reduces to simply noticing\n    that the cpuset_memory_pressure_enabled flag is zero.  So only\n    systems that enable this feature will compute the metric.\n\nWhy a per-cpuset, running average:\n\n    Because this meter is per-cpuset, rather than per-task or mm, the\n    system load imposed by a batch scheduler monitoring this metric is\n    sharply reduced on large systems, because a scan of the tasklist can be\n    avoided on each set of queries.\n\n    Because this meter is a running average, instead of an accumulating\n    counter, a batch scheduler can detect memory pressure with a single\n    read, instead of having to read and accumulate results for a period of\n    time.\n\n    Because this meter is per-cpuset rather than per-task or mm, the\n    batch scheduler can obtain the key information, memory pressure in a\n    cpuset, with a single read, rather than having to query and accumulate\n    results over all the (dynamically changing) set of tasks in the cpuset.\n\nA per-cpuset simple digital filter (requires a spinlock and 3 words of data\nper-cpuset) is kept, and updated by any task attached to that cpuset, if it\nenters the synchronous (direct) page reclaim code.\n\nA per-cpuset file provides an integer number representing the recent\n(half-life of 10 seconds) rate of direct page reclaims caused by the tasks\nin the cpuset, in units of reclaims attempted per second, times 1000.\n\nSigned-off-by: Paul Jackson \u003cpj@sgi.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

This entry\ncontrols the fraction of pages at most in each zone that are allocated for\neach per cpu page list.  The min value for this is 8.  It means that we\ndon\u0027t allow more than 1/8th of pages in each zone to be allocated in any\nsingle per_cpu_pagelist.\n\nThe batch value of each per cpu pagelist is also updated as a result.  It\nis set to pcp-\u003ehigh/4.  The upper limit of batch is (PAGE_SHIFT * 8)\n\nSigned-off-by: Rohit Seth \u003crohit.seth@intel.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
