[PATCH 0/63] Basic scheduler support for automatic NUMA balancing V8

From: Mel Gorman
Date: Fri Sep 27 2013 - 09:27:58 EST

Weighing in at 63 patches makes the term "basic" in the series title is
a misnomer.

This series still has roughly the same goals as previous versions. It
reduces overhead of automatic balancing through scan rate reduction
and the avoidance of TLB flushes. It selects a preferred node and moves
tasks towards their memory as well as moving memory toward their task. It
handles shared pages and groups related tasks together. Some problems such
as shared page interleaving and properly dealing with processes that are
larger than a node are being deferred.

It is still based on 3.11 because that's what I was testing against. If
we can agree this should be merged to -tip for testing I'll rebase to deal
with any scheduler conflicts but for now I do not want to invalidate other
peoples testing. The only obvious thing that is missing is hotplug handling.
Peter is currently working on reducing [get|put]_online_cpus overhead so
that it can be added to migrate_swap.

Peter, some of your patches are missing signed-offs-by -- 4-5, 43 and 55.

o Pass in correct node information for THP hinting faults
o Pressure tasks sharing a THP page to move towards same node
o Do not set pmd_numa if false sharing is detected

Changelog since V2
o Reshuffle to match Peter's implied preference for layout

easier to evaluate the impact
o Use PID information to identify private accesses
o Set the floor for PTE scanning based on virtual address space scan rates
instead of time
o Some locking improvements
o Do not preempt pinned tasks unless they are kernel threads

Changelog since V1
o Scan pages with elevated map count (shared pages)
o Scale scan rates based on the vsz of the process so the sampling of the
task is independant of its size
o Favour moving towards nodes with more faults even if it's not the
preferred node
o Laughably basic accounting of a compute overloaded node when selecting
the preferred node.
o Applied review comments

This series integrates basic scheduler support for automatic NUMA balancing.
It was initially based on Peter Ziljstra's work in "sched, numa, mm:
Add adaptive NUMA affinity support" but deviates too much to preserve
Signed-off-bys. As before, if the relevant authors are ok with it I'll
add Signed-off-bys (or add them yourselves if you pick the patches up).
There has been a tonne of additional work from both Peter and Rik van Riel.

Some reports indicate that the performance is getting close to manual
bindings for some workloads but your mileage will vary. As before, the
intention is not to complete the work but to incrementally improve mainline
and preserve bisectability for any bug reports that crop up.

Patch 1 is a monolithic dump of patches thare are destined for upstream that
this series indirectly depends upon.

Patches 2-3 adds sysctl documentation and comment fixlets

Patch 4 avoids accounting for a hinting fault if another thread handled the
fault in parallel

Patches 5-6 avoid races with parallel THP migration and THP splits.

Patch 7 corrects a THP NUMA hint fault accounting bug

Patches 8-9 avoids TLB flushes during the PTE scan if no updates are made

Patch 10 sanitizes task_numa_fault callsites to have consist semantics and
always record the fault based on the correct location of the page.

Patch 11 closes races between THP migration and PMD clearing.

Patch 12 avoids trying to migrate the THP zero page

Patch 13 avoids the same task being selected to perform the PTE scan within
a shared address space.

Patch 14 continues PTE scanning even if migration rate limited

Patch 15 notes that delaying the PTE scan until a task is scheduled on an
alternative node misses the case where the task is only accessing
shared memory on a partially loaded machine and reverts a patch.

Patch 16 initialises numa_next_scan properly so that PTE scanning is delayed
when a process starts.

Patch 17 sets the scan rate proportional to the size of the task being
scanned.

Patch 18 slows the scan rate if no hinting faults were trapped by an idle task.

Patch 19 tracks NUMA hinting faults per-task and per-node

Patches 20-24 selects a preferred node at the end of a PTE scan based on what
node incurred the highest number of NUMA faults. When the balancer
is comparing two CPU it will prefer to locate tasks on their
preferred node. When initially selected the task is rescheduled on
the preferred node if it is not running on that node already. This
avoids waiting for the scheduler to move the task slowly.

Patch 25 adds infrastructure to allow separate tracking of shared/private
pages but treats all faults as if they are private accesses. Laying
it out this way reduces churn later in the series when private
fault detection is introduced

Patch 26 avoids some unnecessary allocation

Patch 27-28 kicks away some training wheels and scans shared pages and
small VMAs.

Patch 29 introduces private fault detection based on the PID of the faulting
process and accounts for shared/private accesses differently.

Patch 30 avoids migrating memory immediately after the load balancer moves
a task to another node in case it's a transient migration.

Patch 31 avoids scanning VMAs that do not migrate-on-fault which addresses
a serious regression on a database performance test.

Patch 32 pick the least loaded CPU based on a preferred node based on
a scheduling domain common to both the source and destination
NUMA node.

Patch 33 retries task migration if an earlier attempt failed

Patch 34 will begin task migration immediately if running on its preferred
node

Patch 35 will avoid trapping hinting faults for shared read-only library
pages as these never migrate anyway

Patch 36 avoids handling pmd hinting faults if none of the ptes below it were
marked pte numa

Patches 37-38 introduce a mechanism for swapping tasks

Patch 39 uses a system-wide search to find tasks that can be swapped
to improve the overall locality of the system.

Patch 40 notes that the system-wide search may ignore the preferred node and
will use the preferred node placement if it has spare compute
capacity.

Patch 41 will perform a global search if a node that should have had capacity
cannot have a task migrated to it

Patches 42-43 use cpupid to track pages so potential sharing tasks can
be quickly found

Patch 44 reports the ID of the numa group a task belongs.

Patch 45 copies the cpupid on page migration

Patch 46 avoids grouping based on read-only pages

Patch 47 stops handling pages within a PMD in batch as it distorts fault
statistics and failed to flush TLBs correctly.

Patch 48 schedules new threads on the same node as the parent.

Patch 49 schedules tasks based on their numa group

Patch 50 cleans up tasks numa_group on exec

Patch 51 avoids parallel updates to group stats

Patch 52 adds some debugging aids

Patches 53-54 separately considers task and group weights when selecting the node to
schedule a task on

Patch 56 checks if PID truncation may have caused false matches before joining tasks
to a NUMA grou

Patch 57 uses the false shared detection information for scan rate adaption later

Patch 58 adapts the scan rate based on local/remote faults

Patch 59 removes the period scan rate reset

Patch 60-61 throttles shared page migrations

Patch 62 avoids the use of atomics protects the values with a spinlock

Patch 63 periodically retries migrating a task back to its preferred node

Kernel 3.11 is the testing baseline.

Mostly flat but it's interesting to note what a large impact the periodic
migration of tasks to their preferred node is.

In general, the numa01 (adverse workload) is hurt by the series until the
periodic retry patch is merged. In general that patch helps a lot except
in the case of numa02_SMT where it punished severely. It's odd because the
amount of system CPU usage that workload incurs is tiny.

This is looking much better overall and again the impact of the continual
retries of migration makes a big difference. It indicates that it would
be worth investigating why the retries are even necessary. It would be
unfortunate if NUMA scheduling was constantly battling the load balancer.

That migrate retry thing does wonders for the local fault percentage. Really worth checking out
why tasks are getting migrated off their preferred node.

The NAS parallel benchmarks had not run at the time of writing but I decided not to delay releasing
this anyway.

Overall this series is now looking much better. The hotplug handling part
is still missing but hopefully with Peter overhead reduction efforts it
will not impair the results much. The primary curiousity for me is why
the period retry makes such a difference because in my mind it implies
the load balancer and numa scheduler are working against each other for
some reason. Even without that answer I think this should get some time
in tip when the hotplug part is filled in.
