[RFC PATCH v1 00/13] lru_lock scalability

[RFC PATCH v1 00/13] lru_lock scalability

[daniel.m.jordan]

lru_lock, a per-node* spinlock that protects an LRU list, is one of the
hottest locks in the kernel.  On some workloads on large machines, it
shows up at the top of lock_stat.

One way to improve lru_lock scalability is to introduce an array of locks,
with each lock protecting certain batches of LRU pages.

        *ooooooooooo**ooooooooooo**ooooooooooo**oooo ...
        |           ||           ||           ||
         \ batch 1 /  \ batch 2 /  \ batch 3 /  

In this ASCII depiction of an LRU, a page is represented with either '*'
or 'o'.  An asterisk indicates a sentinel page, which is a page at the
edge of a batch.  An 'o' indicates a non-sentinel page.

To remove a non-sentinel LRU page, only one lock from the array is
required.  This allows multiple threads to remove pages from different
batches simultaneously.  A sentinel page requires lru_lock in addition to
a lock from the array.

Full performance numbers appear in the last patch in this series, but this
prototype allows a microbenchmark to do up to 28% more page faults per
second with 16 or more concurrent processes.

This work was developed in collaboration with Steve Sistare.

Note: This is an early prototype.  I'm submitting it now to support my
request to attend LSF/MM, as well as get early feedback on the idea.  Any
comments appreciated.


* lru_lock is actually per-memcg, but without memcg's in the picture it
  becomes per-node.

[RFC PATCH v1 04/13] mm: introduce struct lru_list_head in lruvec to hold per-LRU batch info

[daniel.m.jordan]

Add information about the first and last LRU batches in struct lruvec.

lruvec's list_head is replaced with a pseudo struct page to avoid
special-casing LRU batch handling at the front or back of the LRU.  This
pseudo page has its own lru_batch and lru_sentinel fields so that the
same code that deals with "inner" LRU pages (i.e. neither the first nor
the last page) can deal with the first and last pages.

[RFC PATCH v1 05/13] mm: add batching logic to add/delete/move API's

[daniel.m.jordan]

Change the add/delete/move LRU API's in mm_inline.h to account for LRU
batching.  Now when a page is added to the front of the LRU, it's
assigned a batch number that's used to decide which spinlock in the
lru_batch_lock array to take when removing that page from the LRU.  Each
newly-added page is also unconditionally made a sentinel page.

As more pages are added to the front of an LRU, the same batch number is
used for each until a threshold is reached, at which point a batch is
ready and the sentinel bits are unset in all but the first and last pages
of the batch.  This allows those inner pages to be removed with a batch
lock rather than the heavier lru_lock.

[RFC PATCH v1 05/13] mm: add batching logic to add/delete/move API's

[daniel.m.jordan]

Change the add/delete/move LRU API's in mm_inline.h to account for LRU
batching.  Now when a page is added to the front of the LRU, it's
assigned a batch number that's used to decide which spinlock in the
lru_batch_lock array to take when removing that page from the LRU.  Each
newly-added page is also unconditionally made a sentinel page.

As more pages are added to the front of an LRU, the same batch number is
used for each until a threshold is reached, at which point a batch is
ready and the sentinel bits are unset in all but the first and last pages
of the batch.  This allows those inner pages to be removed with a batch
lock rather than the heavier lru_lock.

[RFC PATCH v1 06/13] mm: add lru_[un]lock_all APIs

[daniel.m.jordan]

Add heavy locking API's for the few cases that a thread needs exclusive
access to an LRU list.  This locks lru_lock as well as every lock in
lru_batch_locks.

This API will be used often at first, in scaffolding code, to ease the
transition from using lru_lock to the batch locking scheme.  Later it
will be rarely needed.

[RFC PATCH v1 07/13] mm: convert to-be-refactored lru_lock callsites to lock-all API

[daniel.m.jordan]

Use the heavy locking API for now to allow us to focus on the path we're
measuring to prove the concept--the release_pages path.  In that path,
LRU batch locking will be used, but everywhere else will be heavy.

For now, exclude compaction since this would be a nontrivial
refactoring.  We can deal with that in a future series.

[RFC PATCH v1 07/13] mm: convert to-be-refactored lru_lock callsites to lock-all API

[daniel.m.jordan]

Use the heavy locking API for now to allow us to focus on the path we're
measuring to prove the concept--the release_pages path.  In that path,
LRU batch locking will be used, but everywhere else will be heavy.

For now, exclude compaction since this would be a nontrivial
refactoring.  We can deal with that in a future series.

[RFC PATCH v1 10/13] mm: add LRU batch lock API's

[daniel.m.jordan]

Add the LRU batch locking API's themselves.  This adds the final piece
of infrastructure necessary for locking batches on an LRU list.

The API's lock a specific page on the LRU list, taking only the
appropriate LRU batch lock for a non-sentinel page and taking the
node's/memcg's lru_lock in addition for a sentinel page.

These interfaces are designed for performance: they minimize the number
of times we needlessly drop and then reacquire the same lock(s) when
used in a loop.  They're difficult to use but will do for a prototype.

[RFC PATCH v1 12/13] mm: split up release_pages into non-sentinel and sentinel passes

[daniel.m.jordan]

A common case in release_pages is for the 'pages' list to be in roughly
the same order as they are in their LRU.  With LRU batch locking, when a
sentinel page is removed, an adjacent non-sentinel page must be promoted
to a sentinel page to follow the locking scheme.  So we can get behavior
where nearly every page in the 'pages' array is treated as a sentinel
page, hurting the scalability of this approach.

To address this, split up release_pages into non-sentinel and sentinel
passes so that the non-sentinel pages can be locked with an LRU batch
lock before the sentinel pages are removed.

For the prototype, just use a bitmap and a temporary outer loop to
implement this.

Performance numbers from a single microbenchmark at this point in the
series are included in the next patch.

[RFC PATCH v1 13/13] mm: splice local lists onto the front of the LRU

[daniel.m.jordan]

Now that release_pages is scaling better with concurrent removals from
the LRU, the performance results (included below) showed increased
contention on lru_lock in the add-to-LRU path.

To alleviate some of this contention, do more work outside the LRU lock.
Prepare a local list of pages to be spliced onto the front of the LRU,
including setting PageLRU in each page, before taking lru_lock.  Since
other threads use this page flag in certain checks outside lru_lock,
ensure each page's LRU links have been properly initialized before
setting the flag, and use memory barriers accordingly.

Performance Results

This is a will-it-scale run of page_fault1 using 4 different kernels.

            kernel     kern #

          4.15-rc2          1
  large-zone-batch          2
     lru-lock-base          3
   lru-lock-splice          4

Each kernel builds on the last.  The first is a baseline, the second
makes zone->lock more scalable by increasing an order-0 per-cpu
pagelist's 'batch' and 'high' values to 310 and 1860 respectively
(courtesy of Aaron Lu's patch), the third scales lru_lock without
splicing pages (the previous patch in this series), and the fourth adds
page splicing (this patch).

N tasks mmap, fault, and munmap anonymous pages in a loop until the test
time has elapsed.

The process case generally does better than the thread case most likely
because of mmap_sem acting as a bottleneck.  There's ongoing work
upstream[*] to scale this lock, however, and once it goes in, my
hypothesis is the thread numbers here will improve.

[RFC PATCH v1 13/13] mm: splice local lists onto the front of the LRU

[daniel.m.jordan]

Now that release_pages is scaling better with concurrent removals from
the LRU, the performance results (included below) showed increased
contention on lru_lock in the add-to-LRU path.

To alleviate some of this contention, do more work outside the LRU lock.
Prepare a local list of pages to be spliced onto the front of the LRU,
including setting PageLRU in each page, before taking lru_lock.  Since
other threads use this page flag in certain checks outside lru_lock,
ensure each page's LRU links have been properly initialized before
setting the flag, and use memory barriers accordingly.

Performance Results

This is a will-it-scale run of page_fault1 using 4 different kernels.

            kernel     kern #

          4.15-rc2          1
  large-zone-batch          2
     lru-lock-base          3
   lru-lock-splice          4

Each kernel builds on the last.  The first is a baseline, the second
makes zone->lock more scalable by increasing an order-0 per-cpu
pagelist's 'batch' and 'high' values to 310 and 1860 respectively
(courtesy of Aaron Lu's patch), the third scales lru_lock without
splicing pages (the previous patch in this series), and the fourth adds
page splicing (this patch).

N tasks mmap, fault, and munmap anonymous pages in a loop until the test
time has elapsed.

The process case generally does better than the thread case most likely
because of mmap_sem acting as a bottleneck.  There's ongoing work
upstream[*] to scale this lock, however, and once it goes in, my
hypothesis is the thread numbers here will improve.

GFS2 has an lru list for glocks, which can be contended under certain 
workloads. Work is still ongoing to figure out exactly why, but this 
looks like it might be a good approach to that issue too. The main 
purpose of GFS2's lru list is to allow shrinking of the glocks under 
memory pressure via the gfs2_scan_glock_lru() function, and it looks 
like this type of approach could be used there to improve the scalability,

The above declaration adds at least 5 bytes to struct page.
It adds a lot of extra memory overhead when multiplied
by the number of pages in the system.

We can move sentinel bool to page flag, at least for 64 bit system.
And 8 bit is probably enough for lru_batch id to give a max 
lru_batch number of 256 to break the locks into 256 smaller ones.  
The max used in the patchset is 32 and that is already giving
pretty good spread of the locking.
It will be better if we can find some unused space in struct page
to squeeze it in.

The speedup looks pretty nice and seems to peak at 16 tasks.  Do you have an explanation of what
causes the drop from 28.2% to 21.9% going from 16 to 64 tasks?  Was
the loss in performance due to increased contention on LRU lock when more tasks running
results in a higher likelihood of hitting the sentinel?  If I understand
your patchset correctly, you will need to acquire LRU lock for sentinel page. Perhaps an increase
in batch size could help?

> GFS2 has an lru list for glocks, which can be contended under certain workloads. Work is still ongoing to figure out exactly why, but this looks like it might be a good approach to that issue too. The main purpose of GFS2's lru list is to allow shrinking of the glocks under memory pressure via the gfs2_scan_glock_lru() function, and it looks like this type of approach could be used there to improve the scalability,

Glad to hear that this could help in gfs2 as well.

Hopefully struct gfs2_glock is less space constrained than struct page for storing the few bits of metadata that this approach requires.

> GFS2 has an lru list for glocks, which can be contended under certain workloads. Work is still ongoing to figure out exactly why, but this looks like it might be a good approach to that issue too. The main purpose of GFS2's lru list is to allow shrinking of the glocks under memory pressure via the gfs2_scan_glock_lru() function, and it looks like this type of approach could be used there to improve the scalability,

Glad to hear that this could help in gfs2 as well.

Hopefully struct gfs2_glock is less space constrained than struct page for storing the few bits of metadata that this approach requires.

There did seem to be room for one more bit the way my kernel was configured (without losing a component in page->flags), but I'd have to look again.

One idea we'd had was to store the batch id in the lower bits of the mem_cgroup pointer.  CONFIG_MEMCG seems to be pretty ubiquitous these days, and it's a large enough struct (1048 bytes on one machine) to have room in the lower bits.

Another way might be to encode the previous and next lru page pointers as pfn's instead of struct list_head *'s, shrinking the footprint of struct page's lru field to allow room for the batch id.

The system I was testing on had 44 cores, so part of the decrease in % speedup is just saturating the hardware (e.g. memory bandwidth).  At 64 processes, we start having to share cores.  Page faults per second did continue to increase each time we added more processes, though, so there's no anti-scaling going on.

That seems to be another factor, yes.  I used lock_stat to measure it, and it showed that wait time on lru_lock nearly tripled when going from 32 to 64 processes, but I also take lock_stat with a grain of salt as it changes the timing/interaction between processes.

Actually, I did try doing that.  In this series the batch size is PAGEVEC_SIZE (14).  When I did a run with PAGEVEC_SIZE*4, the performance stayed nearly the same for all but the 64 process case, where it dropped by ~10%.  One explanation is as a process runs through one batch, it holds the batch lock longer before it has to switch batches, creating more opportunity for contention.


By the way, we're also working on another approach to scaling this look:
     https://marc.info/?l=linux-mm&m=151746028405581

We plan to implement that idea and see how it compares performance-wise and diffstat-wise with this.

The system I was testing on had 44 cores, so part of the decrease in % speedup is just saturating the hardware (e.g. memory bandwidth).  At 64 processes, we start having to share cores.  Page faults per second did continue to increase each time we added more processes, though, so there's no anti-scaling going on.

That seems to be another factor, yes.  I used lock_stat to measure it, and it showed that wait time on lru_lock nearly tripled when going from 32 to 64 processes, but I also take lock_stat with a grain of salt as it changes the timing/interaction between processes.

Actually, I did try doing that.  In this series the batch size is PAGEVEC_SIZE (14).  When I did a run with PAGEVEC_SIZE*4, the performance stayed nearly the same for all but the 64 process case, where it dropped by ~10%.  One explanation is as a process runs through one batch, it holds the batch lock longer before it has to switch batches, creating more opportunity for contention.


By the way, we're also working on another approach to scaling this look:
     https://marc.info/?l=linux-mm&m=151746028405581

We plan to implement that idea and see how it compares performance-wise and diffstat-wise with this.

Since the purpose of the patchset is to optimize lru_lock, you may
consider adjusting pcp->high to be >= 32768(page_fault1's test size is
128M = 32768 pages). That should eliminate zone->lock contention
entirely.

We obviously want to keep gfs2_glock small, however within reason then 
yet we can add some additional fields as required. The use case is 
pretty much a standard LRU list, so items are added and removed, mostly 
at the active end of the list, and the inactive end of the list is

While running your series rebased on v4.15-mmotm-2018-01-31-16-51, I'm
hitting this VM_BUG sometimes on a ppc64 system where page size is set to 64K.
In my case, nr=537 while LRU_BITMAP_SIZE is 512. Here is the stack trace

While running your series rebased on v4.15-mmotm-2018-01-31-16-51, I'm
hitting this VM_BUG sometimes on a ppc64 system where page size is set to 64K.
In my case, nr=537 while LRU_BITMAP_SIZE is 512. Here is the stack trace
displayed :

Why not include the call to smp_rmb() in del_page_from_lru_list() instead
of spreading smp_rmb() before calls to del_page_from_lru_list() ?

I can't see any link between nr and LRU_BITMAP_SIZE, caller may pass a
larger list of pages which is not relative to the LRU list.

To move forward seeing the benefit of this series with the SPF one, I
declared the bit map based on nr. This is still not a valid option but this
at least allows to process all the passed pages.

Interesting, hadn't thought about taking zone->lock completely out of 
the equation.  Will try this next time I test this series.


While we're on this topic, it does seem from the performance of kernel 
#2, and the numbers Aaron posted in a previous thread[*], that the 
default 'batch' and 'high' values should be bigger on large systems.

The code to control these two values last changed in 2005[**], so we hit 
the largest values with just a 512M zone:

    zone       4k_pages  batch   high  high/4k_pages
     64M         16,384      3     18       0.10986%

You're correct, I used the hard-coded size to quickly prototype, just to 
see how this approach performs.  That's unfortunate that it bit you.

Yes, the bitmap's not for the final version.

Yes, this is what I should have done.  The memory barriers came from 
another patch I squashed in and I didn't look back to see how obvious 
the encapsulation was.

Do you have details on which callsites are causing the problem?  That
would permit us to consider other approaches, perhaps.

Sure, there are two paths where we're seeing contention.

In the first one, a pagevec's worth of anonymous pages are added to 
various LRUs when the per-cpu pagevec fills up:

   /* take an anonymous page fault, eventually end up at... */
   handle_pte_fault
     do_anonymous_page
       lru_cache_add_active_or_unevictable
         lru_cache_add
           __lru_cache_add
             __pagevec_lru_add
               pagevec_lru_move_fn
                 /* contend on lru_lock */


In the second, one or more pages are removed from an LRU under one hold 
of lru_lock:

   // userland calls munmap or exit, eventually end up at...
   zap_pte_range
     __tlb_remove_page // returns true because we eventually hit
                       // MAX_GATHER_BATCH_COUNT in tlb_next_batch
     tlb_flush_mmu_free
       free_pages_and_swap_cache
         release_pages
           /* contend on lru_lock */


For a broader context, we've run decision support benchmarks where 
lru_lock (and zone->lock) show long wait times. But we're not the only 
ones according to certain kernel comments:

mm/vmscan.c:
  * zone_lru_lock is heavily contended.  Some of the functions that
  * shrink the lists perform better by taking out a batch of pages
  * and working on them outside the LRU lock.
  *
  * For pagecache intensive workloads, this function is the hottest
  * spot in the kernel (apart from copy_*_user functions).
...
static unsigned long isolate_lru_pages(unsigned long nr_to_scan,


include/linux/mmzone.h:
  * zone->lock and the [pgdat->lru_lock] are two of the hottest locks in 
the kernel.
  * So add a wild amount of padding here to ensure that they fall into 
separate
  * cachelines. ...


Anyway, if you're seeing this lock in your workloads, I'm interested in 
hearing what you're running so we can get more real world data on this.
