[PATCH v3 0/2] sched/fair: Choose the CPU where short task is running during wake up

[PATCH v3 0/2] sched/fair: Choose the CPU where short task is running during wake up

[Chen Yu]

The main purpose of this change is to avoid too many cross CPU
wake up when it is unnecessary. The frequent cross CPU wake up
brings significant damage to some workloads, especially on high
core count systems.

This patch set inhibits the cross CPU wake-up by placing the wakee
on waking CPU or previous CPU, if both the waker and wakee are
short-duration tasks.

The first patch is to introduce the definition of a short-duration
task. The second patch leverages the first patch to choose a local
or previous CPU for wakee.

This version is modified based on the following feedback on v2:

1. Peter suggested comparing the duration of waker and the cost to
   scan for an idle CPU: If the cost is higher than the task duration,
   do not waste time finding an idle CPU, choose the local or previous
   CPU directly. A prototype was created based on this suggestion.
   However, according to the test result, this prototype does not inhibit
   the cross CPU wakeup and did not bring improvement. Because the cost
   to find an idle CPU is small in the problematic scenario. The root
   cause of the problem is a race condition between scanning for an idle
   CPU and task enqueue(please refer to the commit log in PATCH 2/2).
   So v3 does not change the core logic of v2, with some refinement based
   on Peter's suggestion.

2. Simplify the logic to record the task duration per Peter and Abel's suggestion.

This change brings overall improvement on some microbenchmarks, both on
Intel and AMD platforms.

[PATCH v3 1/2] sched/fair: Introduce short duration task check

[Chen Yu]

Introduce short-duration task checks, as there is requirement
to leverage this attribute for better task placement.

There are several choices of metrics that could be used to
indicate if a task is a short-duration task.

At first thought the (p->se.sum_exec_runtime / p->nvcsw)
could be used to measure the task duration. However, the
history long past was factored too heavily in such a formula.
Ideally, the old activity should decay and not affect
the current status too much.

Although something based on PELT could be used, se.util_avg might
not be appropriate to describe the task duration:
1. Task p1 and task p2 are doing frequent ping-pong scheduling on
   one CPU, both p1 and p2 have a short duration, but the util_avg
   can be up to 50%.
2. Suppose a task lasting less than 4ms is regarded as a short task.
   If task p3 runs for 6ms and sleeps for 32ms, p3 should not be a
   short-duration task. However, PELT would decay p3's accumulated
   running time from 6ms to 3ms, because 32ms is the half-life in PELT.
   As a result, p3 would be incorrectly treated as a short task.

It was found that there was once a similar feature to track the
duration of a task, which is in Commit ad4b78bbcbab ("sched: Add
new wakeup preemption mode: WAKEUP_RUNNING"). Unfortunately, it
was reverted because it was an experiment. So pick the patch up
again, by recording the average duration when a task voluntarily
switches out. Introduce SIS_SHORT to control this strategy.

The threshold of short duration reuses sysctl_sched_min_granularity,
so it can be tuned by the user. Ideally there should be a dedicated
parameter for the threshold, but that might introduce complexity.

[PATCH v3 2/2] sched/fair: Choose the CPU where short task is running during wake up

[Chen Yu]

[Problem Statement]
For a workload that is doing frequent context switches, the throughput
scales well until the number of instances reaches a peak point. After
that peak point, the throughput drops significantly if the number of
instances continues to increase.

The will-it-scale context_switch1 test case exposes the issue. The
test platform has 112 CPUs per LLC domain. The will-it-scale launches
1, 8, 16 ... 112 instances respectively. Each instance is composed
of 2 tasks, and each pair of tasks would do ping-pong scheduling via
pipe_read() and pipe_write(). No task is bound to any CPU.
It is found that, once the number of instances is higher than
56(112 tasks in total, every CPU has 1 task), the throughput
drops accordingly if the instance number continues to increase:

          ^
throughput|
          |                 X
          |               X   X X
          |             X         X X

          |   X

                            56
                                 number of instances

[Symptom analysis]

The performance downgrading was caused by a high system idle
percentage(around 20% ~ 30%). The CPUs waste a lot of time in
idle and do nothing. As a comparison, if set CPU affinity to
these workloads and stops them from migrating among CPUs,
the idle percentage drops to nearly 0%, and the throughput
increases by about 300%. This indicates room for optimization.

The reason for the high idle percentage is different before/after
commit f3dd3f674555 ("sched: Remove the limitation of WF_ON_CPU
on wakelist if wakee cpu is idle").

[Before the commit]
The bottleneck is the runqueue spinlock.

48                   1.63%

104                  13.54%
112                  15.13%

And top 2 rq lock hot paths:

(path1):
raw_spin_rq_lock_nested.constprop.0;
try_to_wake_up;
default_wake_function;
autoremove_wake_function;
__wake_up_common;
__wake_up_common_lock;

vfs_write;
ksys_write;
__x64_sys_write;
do_syscall_64;

(path2):
raw_spin_rq_lock_nested.constprop.0;
__sched_text_start;
schedule_idle;
do_idle;
cpu_startup_entry;
start_secondary;
secondary_startup_64_no_verify

task A tries to wake up task B on CPU1, then task A grabs the
runqueue lock of CPU1. If CPU1 is about to quit idle, it needs
to grab its lock which has been taken by someone else. Then
CPU1 takes more time to quit which hurts the performance.

[After the commit]
The cause is the race condition between select_task_rq() and
the task enqueue.

Suppose there are nr_cpus pairs of ping-pong scheduling
tasks. For example, p0' and p0 are ping-pong scheduling,
so do p1' <=> p1, and p2'<=> p2. None of these tasks are
bound to any CPUs. The problem can be summarized as:
more than 1 wakers are stacked on 1 CPU, which slows down
waking up their wakees:

CPU0					CPU1				CPU2

p0'					p1' => idle			p2'

try_to_wake_up(p0)							try_to_wake_up(p2);
CPU1 = select_task_rq(p0);						CPU1 = select_task_rq(p2);
ttwu_queue(p0, CPU1);							ttwu_queue(p2, CPU1);
  __ttwu_queue_wakelist(p0, CPU1); =>	ttwu_list->p0
					quiting cpuidle_idle_call()

					ttwu_list->p2->p0	<=	  __ttwu_queue_wakelist(p2, CPU1);

    WRITE_ONCE(CPU1->ttwu_pending, 1);					    WRITE_ONCE(CPU1->ttwu_pending, 1);

p0' => idle
					sched_ttwu_pending()
					  enqueue_task(p2 and p0)

					idle => p2

					...
					p2 time slice expires
					...
									!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
								<===	!!! p2 delays the wake up of p0' !!!
									!!! causes long idle on CPU0     !!!
					p2 => p0			!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
					p0 wakes up p0'

idle => p0'



Since there are many waker/wakee pairs in the system, the chain reaction
causes many CPUs to be victims. These idle CPUs wait for their waker to
be scheduled.

Actually Tiancheng has mentioned above issue here[2].

[Proposal]
The root cause is that there is no strict synchronization of select_task_rq()
and the set of ttwu_pending flag among several CPUs. And this might be by
design because the scheduler prefers parallel wakeup.

So avoid this problem indirectly. If a system does not have idle cores,
and if the waker and wakee are both short duration tasks, wake up the wakee on
the same CPU as waker.

The reason is that, if the waker is a short-duration task, it might
relinquish the CPU soon, and the wakee has the chance to be scheduled.
On the other hand, if the wakee is a short duration task, putting it on
non-idle CPU would bring minimal impact to the running task. No idle
core in the system indicates that this mechanism should not inhibit
spreading the tasks if the system have idle core.

[Benchmark results]
The baseline is v6.1-rc6. The test platform has 56 Cores(112 CPUs) per
LLC domain. C-states deeper than C1E are disabled. Turbo is disabled.
CPU frequency governor is performance.

In summary, overall there is no significant performance regression detected
and there is a big improvement in netperf/tbench in partially-busy cases.

[Limitations]
As Peter said, the criteria of a short duration task is intuitive, but it
seems to be hard to find an accurate criterion to describe this.

This wake up strategy can be viewed as dynamic WF_SYNC. Except that:
1. Some workloads do not have WF_SYNC set.
2. WF_SYNC does not treat non-idle CPU as candidate target CPU.

Peter has suggested[1] comparing task duration with the cost of searching
for an idle CPU. If the latter is higher, then give up the scan, to
achieve better task affine. However, this method does not fit in the case
encountered in this patch. Because there are plenty of idle CPUs in the system,
it will not take too long to find an idle CPU. The bottleneck is caused by the
race condition mentioned above.

Hi Yu,

I still have a bit concern about the sysctl_sched_min_granularity 
stuff.. This grab can be set to different value which will impact the 
action of this patch and make things not totally under control.

Not sure if we can add a new grab for this.. The test result shows good 
improvement for short task, and with this grab, admins will be able to 
custom the system base on their own 'short task' view.

Thanks,
Honglei

It would be ideal to have a dedicated parameter to tweak this. For example,
something under /sys/kernel/debug/sched/, and initilized to sysctl_sched_min_granularity
by default. 
Hi Peter, Vincent,
may I have your opinion if this is applicable?

There are already ways to misconfigure sched sysctl to make bad/weird things happen.

It would be nice to not have to introduce a new knob for this. IMO, min_granularity is reasonable.

First I want to say that this issue (race condition between selecting idle cpu 
and enqueuing task) always exists before or after the commit f3dd3f674555. And I 
know this is a big issue so in [2] I only try to fix a small part of it. Of 
course I'm glad to see you trying solving this issue too :-)

There may be a bit wrong in your comment about the order. 
"WRITE_ONCE(CPU1->ttwu_pending, 1);" on CPU0 is earlier than CPU1 getting 
"ttwu_list->p0", right?

Thanks.

Sorry for the late answer.
We don't want to add more dedicated knobs. So using
sysctl_sched_min_granularity as you are doing in this patch looks ok

Is it necessary to check the ttwu pending state here and below?

A short running task doesn't means a low utilization (you also mentioned in Patch 1/2).
So should we concern that we may overload the target?

btw, we're doing no scanning here so I may think it'll be more consistent to put this part
in select_idle_siblings(), considering we've already have some similiar judgement for the
prev_cpu, recent_used_cpu, etc. there.

Still doing some test, will reply the results once I get them.

Thanks,

If not a knob, then maybe at least a smaller hardcoded value? Several
milliseconds seems like too long for this optimization; the
opportunity cost of not doing the idle search likely doesn't make
sense if the waker is going to be active for several additional
milliseconds. I would have guessed something on the order of 100us.

Chen, what is the run duration of tasks in your ping pong example?

My understanding is that, ttwu_pending will be set on this_cpu if
1) this_cpu is idle, or
2) waker on another LLC domain wants to wake up the wakee on this_cpu,
see ttwu_queue_cond().
For 1), the nr_running is 1, so it is not idle. For 2) the
chance to do a cross LLC wake up is relatively low with current patch
applied. Besides, I was trying to make this proposal a dynamic version
of WF_SYNC, since the latter does not check ttwu_pending, I did
not add this check as well.(for now)+

The overloaded target might be expected in this case IMO. Because for a ping-pong scheduling
pair, we want to saturate the target CPU to eliminate the idle time. And this strategy
only takes effect when !has_idle_core.

Thanks for the test, we can tune this patch when we have the data.

OK, I'll measure the duration of all the tests and summarize the data later.

If we decide to use sysctl_sched_min_granularity as the threshold of a short
task, can we also export p->se.dur_avg (somewhere like /proc/[pid]/sched)?
It may be helpful to choose a proper value for sysctl_sched_min_granularity.

Thanks.

This looks reasonable, I can add one in next version.
BTW, I've changed the threshold to (sysctl_sched_min_granularity / 8) in my next
version, as this is the value that fit my previous test case and also not to break
the case Josh mentioned. Also I've changed the place where dur_avg is updated from
put_prev_task() to dequeue_task(), which could fix an issue in v3. Will send v4
out after the test finished.

Do you mean a hardcoded value of some number of micros, or literally
sched_min_granularity / 8? I don't think the latter is necessary, and
indeed can lead to weirdness if min_gran is too small or too large. I
don't think the concept of what a short duration task is should
expand/contract with min_gran.

Best,
Josh

The latter. According to the test, the average task duration when system
is under heavy load:
6 ~ 9 us for netperf
7 ~ 70 us for hackbench
7 ~ 8 us for tbench
13 ~ 20 ms for schbench
Overall the duration of the micros are quite small(except for schbench).
The default sysctl_sched_min_granularity is 750 us in kernel if no user
has changed it. Then 750 / 8 = 93 us, which is close to what you suggested(100us).
On the other hand, if someone changes sysctl_sched_min_granularity,
then '8' can be viewed as log2(256). That is, if there are 256 CPUs online,
and the sysctl_sched_min_granularity is changed to 750 us * log2(256) by
the user, we can devide the sysctl_sched_min_granularity by 8 in case the
sysctl_sched_min_granularity is too large.

My concern of using hardcoded value is that, this value depends on how fast
the CPU runs(cpu frequency). The value I measured above is when the
CPU is running at 1.9Ghz. If a CPU runs faster, a hard code value might not
be appropriate and could not be tuned.

The value of sysctl_sched_min_granularity might indicate how long the
user would like a task to run at least. If the user enlarge this value,
does it mean the user wants every task in the system to run longer?
From this point I found connection between the the definition of short task
duration and this value. I'm open to changing this value to a fixed one, may
I have more insights on how this value would be set in production environment?

Hi Yu,

Seems there is a min_t() call in get_update_sysctl_factor(). In most 
cases, we'll get 750 us * (1+log2(8)) = 3000 us in default due to 
sysctl_sched_tunable_scaling is set as '1' default. (Correct me if I 
misunderstand).

For the value in production environment, I've seen 10 ms and 3 ms in 
different place, FYI. Hope this help.

Thanks,
Honglei

Thanks for pointing this out! I overlooked this part previously.
So (sysctl_sched_min_granularity / 8) is 375 us by default.
> For the value in production environment, I've seen 10 ms and 3 ms in
> different place, FYI. Hope this help.
I see. 10 ms would generate a short duration threshold of 1.25 ms. From
my understanding if the user increases the sysctl_sched_min_granularity
then it is expected to have longer average duration tasks in the system.
And the short duration threshold should also be raised.
