PATCH 1/3 zram: rename IO processing functions

Currently, IO processing functions works synchronously. Let's clear it because later patches will introduce asynchronous IO functions.

As well renaming, it moves zram meta reference counting logic into IO processing functions because it should be done in IO service routine, not IO request routine, logically.

It also moves discard IO logic out of IO processing functions because it's rare so it's not critical for performance so I want to factor it out and handle discard commonly without needing discard logic into asynchronous IO processing functions.

PATCH 2/3 zram: support page-based parallel write

zram supports stream-based parallel compression. IOW, it can support parallel compression on SMP system only if each cpus has streams. For example, assuming 4 CPU system, there are 4 sources for compressing in system and each source must be located in each CPUs for full parallel compression.

So, if there is *one* stream in the system, it cannot be compressed in parallel although the system supports multiple CPUs. This patch aims to overcome such weakness.

The idea is to use multiple background threads to compress pages in idle CPU and foreground just queues BIOs without interrupting while other CPUs consumes pages in BIO to compress.
It means zram begins to support asynchronous writeback to increase write bandwidth.

1) test cp A to B as an example of single stream compression and enhanced 36%.

For single stream, it is much better or tie for many cases but 4-stream cases, but seem to be not true. It's expected because asynchronous IO causes more allocations, instructions, context sw and lock contention so it loses 4~5% in write benchmark. Therefore, asynchronous model is not win for full-stream workload compared to old. Also, it wouldn't be good for power-sensitive system so I want to make it optinal feature at this moment.

sorry for long reply.

frankly speaking, sorry, I'm very skeptical about the patch set.

from your tests it seems that only a tiny corner case can gain some extra performance: when we have SMP system with multiple CPUs, but *guaranteed* only one process doing *only* one type of requests. as soon as this process starts to do things simultaneously (like mixed READ-WRITE) _or_ there are several processes: we are done. and for that tiny corner case we are about to add a complex logic and a big pile of code. I'm quite sure I'll never enable CONFIG_ZRAM_ASYNC_IO. why would you enable it? I mean what setups you are looking at that will benefit? hosting a CVS repository? :) just kidding.

are there any block devices being specifically optimized for a "one process doing one OP" cases?

my tests show a dramatic performance drop down with NEW zram. even "one" process case (one fio job) is almost x3 slower. somtimes WRITE test case even go from MB/s to KB/s

Re: [PATCH 2/3] zram: support page-based parallel write

Hi Sergey,

Quoted 30 lines · Sergey Senozhatsky

Hello Minchan,

Quoted 27 lines · Minchan Kim

zram supports stream-based parallel compression. IOW, it can support parallel compression on SMP system only if each cpus has streams. For example, assuming 4 CPU system, there are 4 sources for compressing in system and each source must be located in each CPUs for full parallel compression.

So, if there is *one* stream in the system, it cannot be compressed in parallel although the system supports multiple CPUs. This patch aims to overcome such weakness.

The idea is to use multiple background threads to compress pages in idle CPU and foreground just queues BIOs without interrupting while other CPUs consumes pages in BIO to compress.
It means zram begins to support asynchronous writeback to increase write bandwidth.

1) test cp A to B as an example of single stream compression and enhanced 36%.

x86_64, 4 CPU
Copy kernel source to zram
old: 3.4s, new: 2.2s

2) test per-process reclaim to swap: 524M
x86_64, 4 CPU:
old: 1.2s new: 0.3s

3) FIO benchamrk
random read was worse so it supports only write at the moment. Later, We might revisit asynchronous read.

sorry for long reply.

Never mind. Better to late response rather than no-reply. ;) And thanks for the testing!

Quoted 2 lines

frankly speaking, sorry, I'm very skeptical about the patch set.

It seems I was not good sales guy. Let me try again.

Quoted 10 lines

from your tests it seems that only a tiny corner case can gain some extra performance: when we have SMP system with multiple CPUs, but *guaranteed* only one process doing *only* one type of requests. as soon as this process starts to do things simultaneously (like mixed READ-WRITE) _or_ there are several processes: we are done. and for that tiny corner case we are about to add a complex logic and a big pile of code. I'm quite sure I'll never enable CONFIG_ZRAM_ASYNC_IO. why would you enable it? I mean what setups you are looking at that will benefit? hosting a CVS repository? :) just kidding.

Could you retest the benchmark without direct IO? Instead of dio, I used fsync_on_close to flush buffered IO.

DIO isn't normal workload compared to buffered IO. The reason I used DIO for zram benchmark was that it's handy to transfer IO to block layer effectively and no-noise of page cache.
If we use buffered IO, the result would be fake as dirty page was just queued in page cache without any flushing.
I think you know already it very well so no need to explan any more. :)

More important thing is current zram is poor for parallel IO. Let's thing two usecases, zram-swap, zram-fs.

1) zram-swap

parallel IO can be done only where every CPU have reclaim context. IOW,

1. kswapd on CPU 0
2. A process direct reclaim on CPU 1
3. process direct reclaim on CPU 2
4. process direct reclaim on CPU 3

I don't think it's usual workload. Most of time, a kswapd and a process direct reclaim in embedded platform workload. The point is we can not use full bandwidth.

2) zram-fs

Currently, there is a work per bdi. So, without fsync(and friends), every IO submit would be done via that work on worker thread. It means the IO couldn't be parallelized. However, if we use fsync, it could be parallelized but it depends on the sync granuarity. For exmaple, if your test application uses fsync directly, the IO would be done in the CPU context your application running on. So, if you has 4 test applications, every CPU could be utilized. However, if you test application doesn't use fsync directly and parant process calls sync if every test child applications, the IO could be done 2 CPU context(1 is parent process context and other is bdi work context).
So, In summary, we were poor for parallel IO workload without sync or DIO.

Quoted 3 lines

are there any block devices being specifically optimized for a "one process doing one OP" cases?

Maybe, above(ie, we were poor for parallel IO workload without sync or DIO) would be enough for justification. But if we need more :) we have used per-process reclaim(e.g., memcg or out-of-tree per-process reclaim whatever). It was direct reclaim context so writeback couldn't use full bandwidth via every CPUs.
NR_CPU times faster would be great. I took experiement on my ARM mahcine(4-CPU). 256 reclaims takes 6sec in old but with async IO, it took 1.6 sec.

Please consider it again.

my tests show a dramatic performance drop down with NEW zram. even "one" process case (one fio job) is almost x3 slower. somtimes WRITE test case even go from MB/s to KB/s

Re: [PATCH 2/3] zram: support page-based parallel write

Hello,

Cc Jens and block-dev,

I'll outline the commit message for Jens and blockdev people, may be someone will have some thoughts/ideas/opinions:

Quoted 1 line · Minchan Kim

: zram supports stream-based parallel compression. IOW, it can support : parallel compression on SMP system only if each cpus has streams. : For example, assuming 4 CPU system, there are 4 sources for compressing : in system and each source must be located in each CPUs for full : parallel compression.
:
: So, if there is *one* stream in the system, it cannot be compressed : in parallel although the system supports multiple CPUs. This patch : aims to overcome such weakness.
:
: The idea is to use multiple background threads to compress pages : in idle CPU and foreground just queues BIOs without interrupting : while other CPUs consumes pages in BIO to compress.
: It means zram begins to support asynchronous writeback to increase : write bandwidth.

is there any way of addressing this issues? [a silly idea] can we, for instance, ask the bock layer to split request and put pages into different queues (assuming that we run in blk-mq mode)? because this looks like a common issue, and it may be a bit too late to fix it in zram driver. any thoughts?

[..]

Could you retest the benchmark without direct IO? Instead of dio, I used fsync_on_close to flush buffered IO.

DIO isn't normal workload compared to buffered IO. The reason I used DIO for zram benchmark was that it's handy to transfer IO to block layer effectively and no-noise of page cache.
If we use buffered IO, the result would be fake as dirty page was just queued in page cache without any flushing.
I think you know already it very well so no need to explan any more. :)

More important thing is current zram is poor for parallel IO. Let's thing two usecases, zram-swap, zram-fs.

well, that's why we use direct=1 in benchmarks - to test the peformance of zram; not anything else. but I can run fsync_on_close=1 tests as well (see later).

1) zram-swap

parallel IO can be done only where every CPU have reclaim context. IOW,

Quoted 8 lines

1. kswapd on CPU 0
2. A process direct reclaim on CPU 1
3. process direct reclaim on CPU 2
4. process direct reclaim on CPU 3

I don't think it's usual workload. Most of time, a kswapd and a process direct reclaim in embedded platform workload. The point is we can not use full bandwidth.

hm. but we are on an SMP system and at least one process had to start direct reclaim, which basically increases chances of direct reclaims from other CPUs, should running processes there request big enough memory allocations. I really see no reasons to rule this possibility out.

Quoted 15 lines

2) zram-fs

Currently, there is a work per bdi. So, without fsync(and friends), every IO submit would be done via that work on worker thread. It means the IO couldn't be parallelized. However, if we use fsync, it could be parallelized but it depends on the sync granuarity. For exmaple, if your test application uses fsync directly, the IO would be done in the CPU context your application running on. So, if you has 4 test applications, every CPU could be utilized. However, if you test application doesn't use fsync directly and parant process calls sync if every test child applications, the IO could be done 2 CPU context(1 is parent process context and other is bdi work context).
So, In summary, we were poor for parallel IO workload without sync or DIO.

but this again looks [to me] like a more general problem which can be addressed somewhere up the stack. zram is not absolutely silly here - it just does what it's being asked to do. any block drivers/block device can suffer from that.

TEST
****

new tests results; same tests, same conditions, same .config. 4-way test:
- BASE zram, fio direct=1
- BASE zram, fio fsync_on_close=1
- NEW zram, fio direct=1
- NEW zram, fio fsync_on_close=1

and what I see is that:
- new zram is x3 times slower when we do a lot of direct=1 IO
and
- 10% faster when we use buffered IO (fsync_on_close); but not always; for instance, test execution time is longer (a reproducible behavior) when the number of jobs equals the number of CPUs - 4.

if flushing is a problem for new zram during direct=1 test, then I would assume that writing a huge number of small files (creat/write 4k/close) would probably have same fsync_on_close=1 performance as direct=1.

my tests show a dramatic performance drop down with NEW zram. even "one" process case (one fio job) is almost x3 slower. somtimes WRITE test case even go from MB/s to KB/s

	WRITE:          3181.4MB/s→      948111KB/s

I've attached the .config

: zram supports stream-based parallel compression. IOW, it can support : parallel compression on SMP system only if each cpus has streams. : For example, assuming 4 CPU system, there are 4 sources for compressing : in system and each source must be located in each CPUs for full : parallel compression.
:
: So, if there is *one* stream in the system, it cannot be compressed : in parallel although the system supports multiple CPUs. This patch : aims to overcome such weakness.
:
: The idea is to use multiple background threads to compress pages : in idle CPU and foreground just queues BIOs without interrupting : while other CPUs consumes pages in BIO to compress.
: It means zram begins to support asynchronous writeback to increase : write bandwidth.

is there any way of addressing this issues? [a silly idea] can we, for instance, ask the bock layer to split request and put pages into different queues (assuming that we run in blk-mq mode)? because this looks like a common issue, and it may be a bit too late to fix it in zram driver. any thoughts?

Hmm, blk-mq works with request-level, not even bio-level. Right? If so, I have a concern about that. Zram as swap storage has been worked with rw_page to avoid bio allocation which was not small and heard from product people it was great enhancement in very pool memory device. I didn't follw up at that time but I guess it was due to waiting free memory from mempool. If blk-rq works with request-level, should we abandon rw_page approach?

Could you retest the benchmark without direct IO? Instead of dio, I used fsync_on_close to flush buffered IO.

DIO isn't normal workload compared to buffered IO. The reason I used DIO for zram benchmark was that it's handy to transfer IO to block layer effectively and no-noise of page cache.
If we use buffered IO, the result would be fake as dirty page was just queued in page cache without any flushing.
I think you know already it very well so no need to explan any more. :)

More important thing is current zram is poor for parallel IO. Let's thing two usecases, zram-swap, zram-fs.

well, that's why we use direct=1 in benchmarks - to test the peformance of zram; not anything else. but I can run fsync_on_close=1 tests as well (see later).

1) zram-swap

parallel IO can be done only where every CPU have reclaim context. IOW,

Quoted 8 lines

1. kswapd on CPU 0
2. A process direct reclaim on CPU 1
3. process direct reclaim on CPU 2
4. process direct reclaim on CPU 3

I don't think it's usual workload. Most of time, a kswapd and a process direct reclaim in embedded platform workload. The point is we can not use full bandwidth.

Quoted 5 lines

hm. but we are on an SMP system and at least one process had to start direct reclaim, which basically increases chances of direct reclaims from other CPUs, should running processes there request big enough memory allocations. I really see no reasons to rule this possibility out.

I didn't rule out the possiblity. It is just one scenario we can use full-bandwidth. However, there are many scenarios we cannot use full-bandwidth.

Imagine that a kswapd waked up and a process entered direct relcaim. The process can get a memory easily with watermark play and go with the memory but kswapd alone should continue to reclaim memory until high watermark. It means there is no process in direct reclaim.

Additionally, with your scenario, we can use just 2 CPU for compression and relies on the luck the hope with 1. other processes in 2. different CPU will 3. allocate memory soon and VM should reclaim 4. anonymous memory, not page cache. It needs many assumptions to use full bandwidth.

However, with current approach, we can use full-bandwidth unconditionally once VM decide to reclaim anonymous memory.
So, I think it's better approach.

2) zram-fs

Quoted 13 lines

Currently, there is a work per bdi. So, without fsync(and friends), every IO submit would be done via that work on worker thread. It means the IO couldn't be parallelized. However, if we use fsync, it could be parallelized but it depends on the sync granuarity. For exmaple, if your test application uses fsync directly, the IO would be done in the CPU context your application running on. So, if you has 4 test applications, every CPU could be utilized. However, if you test application doesn't use fsync directly and parant process calls sync if every test child applications, the IO could be done 2 CPU context(1 is parent process context and other is bdi work context).
So, In summary, we were poor for parallel IO workload without sync or DIO.

Quoted 4 lines

but this again looks [to me] like a more general problem which can be addressed somewhere up the stack. zram is not absolutely silly here - it just does what it's being asked to do. any block drivers/block device can suffer from that.

Agree and hope it can work with rw_page, too.

TEST
****

new tests results; same tests, same conditions, same .config. 4-way test:
- BASE zram, fio direct=1
- BASE zram, fio fsync_on_close=1
- NEW zram, fio direct=1
- NEW zram, fio fsync_on_close=1

Quoted 6 lines

and what I see is that:
- new zram is x3 times slower when we do a lot of direct=1 IO
and
- 10% faster when we use buffered IO (fsync_on_close); but not always; for instance, test execution time is longer (a reproducible behavior) when the number of jobs equals the number of CPUs - 4.

Hmm, strange. with my own old benchmark, it was great enhancement. I will spend a time to test with your benchmark and report back with why. :)

Thanks for the review, Sergey!

if flushing is a problem for new zram during direct=1 test, then I would assume that writing a huge number of small files (creat/write 4k/close) would probably have same fsync_on_close=1 performance as direct=1.

I tested your benchmark for job 1 on my 4 CPU mahcine with this diff.

Nothing different.

1. just changed ordering of test execution - hope to reduce testing time due to block population before the first reading or reading just zero pages
2. used sync_on_close instead of direct io
3. Don't use perf to avoid noise
4. echo 0 > /sys/block/zram0/use_aio to test synchronous IO for old behavior

LZO compression is fast and a CPU for queueing while 3 CPU for compressing it cannot saturate CPU full bandwidth. Nonetheless, it shows 24% enhancement. It could be more in slow CPU like embedded.

LZO compression is fast and a CPU for queueing while 3 CPU for compressing it cannot saturate CPU full bandwidth. Nonetheless, it shows 24% enhancement. It could be more in slow CPU like embedded.

I tested it with deflate. The result is 300% enhancement.

So, curious with your test.
Am my test sync with yours? If you cannot see enhancment in job1, could you test with deflate? It seems your CPU is really fast.

yes, looks like with lzo CPU manages to process bdi writeback fast enough to keep fio-template-static-buffer worker active.

to prove this theory: direct=1 cures zram-deflate.

Isn't it blk-mq you mentioned? With blk-mq, I have some concerns.

1. read speed degradation
2. no work with rw_page
3. more memory footprint by bio/request queue allocation

Having said, it's worth to look into it in detail more. I will have time to see that approach to know what I can do with that.

queue_mode=2 bs=4096 nr_devices=1 submit_queues=4 hw_queue_depth=128

Last week, I played with null_blk and blk-mq.c to get an idea how blk-mq works and I realized it's not good for zram because it aims to solve 1) dispatch queue bottleneck 2) cache-friendly IO completion through IRQ so 3) avoids remote memory accesses.

For zram which is used for embedded as primary purpose, ones listed abvoe are not a severe problem. Most imporant thing is there is no model to support that a process queueing IO request on *a* CPU while other CPUs issues the queued IO to driver.

Anyway, Although blk-mrq can support that model, it is blk-layer thing. IOW, it's software stuff for fast IO delievry but what we need is device parallelism of zram itself. So, although we follow blk-mq, we still need multiple threads to compress in parallel which is most of code I wrote in this patchset.

If I cannot get huge benefit(e.g., reduce a lot of zram-speicif code to support such model) with blk-mq, I don't feel to switch to request model at the cost of reasons I stated above.

Thanks.

Maybe, but it would be rather greedy approach for zram because zram will do real IO(esp, compression which consumed a lot of time) in that context although the context is sharable resource of all processes in the system.

I'm having some troubles understanding the purpose of zram_check_plugged(). it's a global symbol, can you just use it directly? otherwise we are doing additional kmalloc/kfree, spin_lock/unlock and so on.

what am I missing? current->plug? can it affect us? how?

we do zram_meta_get() only once in zram_make_request(). but then put meta for every request in page_list, while a bio passed to __zram_make_async_request() can span across several requests in page_list. right?

who is calling zram_meta_get()? I mean in this loop... what if the loop continues after that `if'?

In this loop, anybody doesn't call zram_meta_get.
It should be called by IO queuing routine. !bio_req case above is rw_page thing so each page_req IO request holds a reference of zram_meta and
in here, service routine release the refernce after IO done.

we do zram_meta_get() only once in zram_make_request(). but then put meta for every request in page_list, while a bio passed to __zram_make_async_request() can span across several requests in page_list. right?

You're right. bio-based request case should be fixed.

Okay. But I think it's not a good idea to hurt wb context you mentioned. IOW, IO queuing could be parallelized by multiple wb context but servicing(i.e., compression) should be done in zram contexts, not wb context.

yep. too many things can go wrong. we can schedule requests on a different die/package/socket, probably pressuring data caches and then there are NUMA systems, and so on and on and on. so I can easily imagine a "fix your user space" response.

PATCH 3/3 zram: adjust the number of zram thread

In reply to Minchan Kim

It's pointless to keep many workers greater than the number of online CPU so adjust the number of worker whenever changing online CPU number.

well, strictly speaking we are have no strict bound-to-cpu (per-cpu) requirement here, we just want to have num_online_cpus() worker threads. if we fail to create one more worker thread nothing really bad happens, so I think we better not block that cpu from coming online. iow, always 'return NOTIFY_OK'.

If it doesn't make code complicated, I will do that in next spin. Thanks.

thanks. I think it won't. we don't really care how many workers we have, because the workers are not per-cpu. we just want to be as parallel as possible, but don't guarantee anything at all: who knows how those workers will be scheduled; may be we even can end up with just one active worker all the time, if other rq-s have higher prio tasks to run. there are many things that can be against us here. that's a massive complication of zram.

preventing CPU from coming online is a bit over-reaction.
