With these patches, and Peter Zijlstra's select_idle_sibling
scalability improvement, Jirka has seen these performance
gains on a 4.11 kernel:

NAS shows improvements in range 20-100%
SPECjbb2005 shows improvements around 6-8% in the single instance mode
SPECjvm2008 - improvements around 10%

Unfortunately the full set of tests takes about a week to
run, so numbers are not broken out for individual patches.

We have done previous runs with other scheduler changes,
which did not work out - they showed improvements on some
workloads, and regressions on others.

4.11 performance still lags behind 3.10 for some workloads.
I am trying to figure out why, and close that gap.

From: Rik van Riel <riel@redhat.com>

Several tests in the NAS benchmark seem to run a lot slower with
NUMA balancing enabled, than with NUMA balancing disabled. The
slower run time corresponds with increased idle time.

Overriding the final test of migrate_degrades_locality (but still
doing the other NUMA tests first) seems to improve performance
of those benchmarks.

Then this_cpu and prev_cpu are in the same socket, select_idle_sibling
will do its thing regardless of the return value of wake_affine. Just
return true and don't look at all the other things.

From: Rik van Riel <riel@redhat.com>

Since select_idle_sibling can place a task anywhere on a socket,
comparing loads between individual CPU cores makes no real sense
for deciding whether to do an affine wakeup across sockets, either.

Instead, compare the load between the sockets in a similar way the
load balancer and the numa balancing code do.

The function effective_load was only used by the NUMA balancing
code, and not by the regular load balancing code. Now that the
NUMA balancing code no longer uses it either, get rid of it.

Note, I removed the first SOB from the commit, assuming that you only meant to 
include the second one?

sched/numa: Override part of migrate_degrades_locality() when idle balancing

Several tests in the NAS benchmark seem to run a lot slower with
NUMA balancing enabled, than with NUMA balancing disabled. The
slower run time corresponds with increased idle time.

Overriding the final test of migrate_degrades_locality (but still
doing the other NUMA tests first) seems to improve performance
of those benchmarks.

sched/fair: Simplify wake_affine() for the single socket case

Then 'this_cpu' and 'prev_cpu' are in the same socket, select_idle_sibling()
will do its thing regardless of the return value of wake_affine().

Just return true and don't look at all the other things.

sched/numa: Implement NUMA node level wake_affine()

Since select_idle_sibling() can place a task anywhere on a socket,
comparing loads between individual CPU cores makes no real sense
for deciding whether to do an affine wakeup across sockets, either.

Instead, compare the load between the sockets in a similar way the
load balancer and the numa balancing code do.

sched/fair: Remove effective_load()

The effective_load() function was only used by the NUMA balancing
code, and not by the regular load balancing code. Now that the
NUMA balancing code no longer uses it either, get rid of it.

Thank you. It looks like I used the wrong email address
in the SOB I wrote in the patch, and git added the second
one automatically. The second one is indeed the one I want.

This seems to assume LLC == NUMA, which isn't strictly so.

Hmm,... funny. It used to be used by wake-affine. I'll have to go check
what happened.

Ah, it fell pray to that LLC == NUMA confusion from the previous patch.

That really looks buggered.

Do the changelog or comments of that patch need fixing,
to avoid LLC / NUMA confusion?

I remember us talking about that in the past, but I do
not remember whether or not I changed the comments after
that discussion...

Neither, I think the code is actually wrong for the case where LLC <
NUMA (a somewhat rare case these days, granted, but something that might
still happen on !x86 perhaps).

Oh, indeed.  I guess in wake_affine() we should test
whether the CPUs are in the same NUMA node, rather than
doing cpus_share_cache() ?

Or, alternatively, have an update_numa_stats() variant
for numa_wake_affine() that works on the LLC level?

Well, since select_idle_sibling() is on LLC; the early test on
cpus_share_cache(prev,this) seems to actually make sense.

But then cutting out all the other bits seems wrong. Not in the least
because !NUMA_BALACING should also still keep working.

I think we want to retain the existing behaviour for everything
larger than LLC, and when NUMA_BALANCING, smaller than NUMA.

Also note that your use of task_h_load() in the new numa thing suffers
from exactly the problem effective_load() is trying to solve.

Even when !NUMA_BALANCING, I suspect it makes little sense
to compare the loads just one the cores in question, since
select_idle_sibling() will likely move the task somewhere
else.

I suspect we want to compare the load on the whole LLC
for that reason, even with NUMA_BALANCING disabled.

What do you mean by this, exactly?

How does the "existing behaviour" of only looking at
the load on two cores make sense when doing LLC-level
task placement?

Are you saying task_h_load is wrong in task_numa_compare()
too, then?  Should both use effective_load()?

But we don't have that data around :/ One thing we could do is try and
keep a copy of the last s*_lb_stats around in the sched_domain_shared
stuff or something and try and use that.

That way we can strictly keep things at the LLC level and not confuse
things with NUMA.

Similarly, we could use that same data to then avoid re-computing things
for the NUMA domain as well and do away with numa_stats.

As you noted, when prev and this are in the same LLC, it doesn't matter
and select_idle_sibling() will do its thing. So anything smaller than
the LLC need not do anything.

When NUMA_BALANCING we have the numa_stats thing and we can, as you
propose use that.

If LLC < NUMA or !NUMA_BALANCING we have a region that needs to do
_something_.

Right, might not be ideal, but its what we have now. Supposedly its
better than not doing anything at all.

But see above for other ideas.

I need more than the few minutes I currently have, but probably. The
question is of course, how much does it matter and how painful will it
be to do it better.

That does seem like a useful optimization, though
I guess we would have to invalidate the cached data
every time we actually move a task?

The current code simply walks all the CPUs in the
cpumask_t, and adds up capacity and load. Doing
that appears to be better than poor task placement
(Jirka's numbers speak for themselves), but optimizing
this code path does seem like a worthwhile goal.

I'll look into it.

Agreed. I will fix this. Given that this is a bit
of a corner case, I guess I can fix this with follow-up
patches, to be merged into -tip before the whole series
is sent on to Linus?

I suspect it does not matter at all currenly, since the 
load balancing code does not use effective_load, and
having the wake_affine logic calculate things differently
from the load balancer is likely to result in both pieces
of code fighting against each other.

I suspect we should either use task_h_load everywhere,
or effective_load everywhere, but not have a mix and
match situation where one is used in some places, and
the other in others.

Thinking about this some more, I suspect that
using effective_load() in combination with
select_idle_sibling(), which will often place
the task on a different CPU than the one specified,
may not lead to entirely useful results...

Ok, so it turns out all of facebook sits inside that corner case because
they have !NUMA_BALANCING.

How does the below patch work?

---
Subject: sched/fair: Fix wake_affine() for !NUMA_BALANCING
From: Peter Zijlstra <peterz@infradead.org>
Date: Mon Jul 31 17:50:05 CEST 2017

In commit:

  3fed382b46ba ("sched/numa: Implement NUMA node level wake_affine()")

Rik changed wake_affine to consider NUMA information when balancing
between LLC domains.

There are a number of problems here which this patch tries to address:

 - LLC < NODE; in this case we'd use the wrong information to balance
 - !NUMA_BALANCING: in this case, the new code doesn't do any
   balancing at all
 - re-computes the NUMA data for every wakeup, this can mean iterating
   up to 64 CPUs for every wakeup.
 - default affine wakeups inside a cache

We address these by saving the load/capacity values for each
sched_domain during regular load-balance and using these values in
wake_affine_llc(). The obvious down-side to using cached values is
that they can be too old and poorly reflect reality.

But this way we can use LLC wide information and thus not rely on
assuming LLC matches NODE. We also don't rely on NUMA_BALANCING nor do
we have to aggegate two nodes (or even cache domains) worth of CPUs
for each wakeup.

Nah, its just me being an idiot and booting the wrong kernel. Unless I
messed up again, this one boots.

There is state during boot and hotplug where there are no domains, and
thus also no shared. Simply ignoring things when that happens should be
good enough I think.

Subject: sched/fair: Fix wake_affine() for !NUMA_BALANCING
From: Peter Zijlstra <peterz@infradead.org>
Date: Mon Jul 31 17:50:05 CEST 2017

In commit:

  3fed382b46ba ("sched/numa: Implement NUMA node level wake_affine()")

Rik changed wake_affine to consider NUMA information when balancing
between LLC domains.

There are a number of problems here which this patch tries to address:

 - LLC < NODE; in this case we'd use the wrong information to balance
 - !NUMA_BALANCING: in this case, the new code doesn't do any
   balancing at all
 - re-computes the NUMA data for every wakeup, this can mean iterating
   up to 64 CPUs for every wakeup.
 - default affine wakeups inside a cache

We address these by saving the load/capacity values for each
sched_domain during regular load-balance and using these values in
wake_affine_llc(). The obvious down-side to using cached values is
that they can be too old and poorly reflect reality.

But this way we can use LLC wide information and thus not rely on
assuming LLC matches NODE. We also don't rely on NUMA_BALANCING nor do
we have to aggegate two nodes (or even cache domains) worth of CPUs
for each wakeup.

We've stumbled across the same regression on Broxton/Apollolake (J3455).

This is still not as effective as the previous code in spreading across
siblings.

I think you mean,

	if (this_stats.has_capacity && this_stats.nr_running + 1 < prev_stats.nr_running)

and with that our particular graphics benchmark behaves similarly to as
before (the regression appears fixed). But I'll let Eero double check.
