This is a full release of all the patches so apologies for the flood. V9 was
just a MIPS build fix and did not justify a full release. V10 includes Ingo's
scalability patches because even though they increase system CPU usage,
they also helped in a number of test cases. It would be worthwhile trying
to reduce the system CPU usage by looking closer at how rwsem works and
dealing with the contended case a bit better. Otherwise the rate of change
in the last few weeks has been tiny as the preliminary objectives had been
met and I did not want to invalidate any testing other people had conducted.

Based on the performance results I have, I still think this tree is what
should be merged for 3.8 with numacore or autonuma rebased on top of it for
3.9. The numacore results are based on an oldish tree. I'm travelling this
week and tip/master crashes and I haven't had the chance to debug it. Worse,
v18 of numacore had a last-minute patch that effectively disabled it. I
reported it (https://lkml.org/lkml/2012/12/4/393) but got no feedback.

There are currently two (three depending on how you look at it) competing
approaches to implement support for automatically migrating pages to
optimise NUMA locality. Performance results are available but review
highlighted different problems in both. They are not compatible with each
other even though some fundamental mechanics should have been the same.
This series addresses part of the integration and sharing problem by
implementing a foundation that either the policy for schednuma or autonuma
can be rebased on.

The initial policy it implements is a very basic greedy policy called
"Migrate On Reference Of pte_numa Node (MORON)". I expect people to
build upon this revised policy and rename it to something more sensible
that reflects what it means. The ideal *worst-case* behaviour is that
it is comparable to current mainline but for some workloads this is an
improvement over mainline.

This series can be treated as 5 major stages.

1. TLB optimisations that we're likely to want unconditionally.
2. Basic foundation and core mechanics, initial policy that does very little
3. Full PMD fault handling, rate limiting of migration, two-stage migration
filter to mitigate poor migration decisions. This will migrate pages
on a PTE or PMD level using just the current referencing CPU as a
placement hint
4. Scan rate adaption
5. Native THP migration

Very broadly speaking the TODOs that spring to mind are

1. Revisit MPOL_NOOP and MPOL_MF_LAZY
2. Other architecture support or at least validation that it could be made work. I'm
half-hoping that the PPC64 people are watching because they tend to be interested
in this type of thing.

Some advantages of the series are;

1. It rate limits migrations to avoid saturating the bus and backs off
PTE scanning (in a fairly heavy manner) if the node is rate-limited
2. It keeps major optimisations like THP towards the end to be sure I am
not accidentally depending on them
3. It implements a basic policy that acts as a second performance baseline.
The three baselines become vanilla kernel, basic placement policy,
complex placement policy. This allows like-with-like comparisons with
implementations.

The comparisons are a bit shorter this time.

Kernels are

stats-v8r6 TLB flush optimisations and stats from this series
numacore-20121130 Tip/master on that date (roughly v17)
numacore-20121202 Tip/master on that date (roughly v18)
autonuma-v28fastr4 Autonuma v28fast rebased and with THP patch on top
balancenuma-v9r2 balancenuma-v9
balancenuma-v10 balancenuma-v10

v9 and v10 only differ by the migration scalability patches. Current
tip/master is crashing during boot and has been crashing for the last few
days which is why it's not included. As I'm remote I have not had the
chance to debug it but it has been reported already. It does mean that
the numacore comparison is old and not based on the unified tree but
right now there is not much I can do about that.

This is less detailed than earlier reports because many of the conclusions
are the same as before.

numacore-20121130 did reasonably well although its system CPU usage is extremely high.

numacore-20121202 is very poor and roughly comparable to mainline. This
is likely because numacore is effectively disabled in this release. The
reasons it is likely disabled have already been reported and current
tip/master looks like it would suffer the same problem if it booted.

balancenuma does reasonably well. It's not great at numa01 which is an adverse
workload as it does not know how to interleave which is what's needed in this
case. It does very well for the other test cases.

numacore-20121130 has very high system CPU usaage.

balancenumas is higher than I'd like but it's acceptable.

numacore is regressing heavily in this case. It's particularly weird for
numacore-20121202 as numacore should be effectively disabled. It's adding
overhead somewhere but not doing anything useful with it.

balancenuma gets about 1/3 of the performance gain of autonuma and the
migration scalabilty patches help quite a lot.

numacore is regressing at the peak and in its overall specjbb score.

balancenuma again is getting some solid performance gains -- not as much as
autonuma but the objective was to be better than mainline, not necessarily
be the best overall. numacore or autonuma can be rebased on top of balancenuma.

numacores system CPU usage is very high. It's not high in 20121202 because it's mostly disabled.

As before, balancenumas is higher than I'd like and the migraiton patches do not hurt.

numacore-20121130 (v17) did well but numacore-20121202 (v18) does not as it's effectively disabled.

autonuma does ok here and balancenuma does quite well. As before, the migration scalability patches help in some cases.

While the migration patches appear to help in some cases note that overall it is not a win in this case. The peak scores are hurt as is the
specjbb score.

Same comments about System CPU time. numacore v17 is very high, v18 is
low because it's disabled, balancenuma is higher than I'd like.

numacore does really badly.

autonuma is ok and balancenuma is ok. Scalability patches do not help as much.

balancenuma is doing reasonably well. It's interesting to note that
the scalabilty patches make little difference to the peak but there
is a difference in the specjbb score. It's veryliekly this is just
variance. balancenuma depends on "luck" on what decisions the scheduler
makes.

numacores CPU usage is off the charts except in v18 where it's more or less disabled.

balancenuma has very high CPU usage too unfortunately.

Overall, balancenuma is not the known best kernel but it wans't meant
to be. It was meant to be better than mainline, establish a performance
baseline and be something that either numacore or autonuma can be rebased
upon. I think it achieves that and is the best choice for 3.8.
