Hi all,

The issue got resolved after the PR https://github.com/openjdk/jdk/pull/27481 got merged recently. The performance of the benchmarks are now acceptable on machines with SVE2.

Thank you for the support.

Subject: Improve scaling of downcalls using MemorySegments allocated with
 shared arenas
Message-ID: <3506dd6c-ef3d-4d4b-972b-fe83bb5debd8@arm.com>

Hello,
	I have encountered a scaling problem with java.lang.foreign.MemorySegments when they are passed to native code. When 
native methods are called with, say, around more than 8 cores with MemorySegments allocated from an Arena allocated from 
Arena.ofShared(), scaling can be sublinear under contention.

 From profiling, it is apparent that excessive time is being spent in jdk.internal.foreign.SharedSession's acquire0 and 
release0 methods. These methods check and increment or decrement the acquireCount field, which is used to prevent the 
SharedSession from being closed if the acquireCount is not zero. it is also used to prevent acquire0 from succeeding if 
the acquireCount is already closed.

The issue can be demonstrated with the micro benchmark:
   org.openjdk.bench.java.lang.foreign. CallOverheadConstant.panama_identity_memory_address_shared_3

It produces the following results on the Neoverse-N1, N2, V1 and V2, Intel Xeon 8375c and the AMD Epyc 9654.

Each machine has >48 cores, and the results are in nanoseconds:

Threads    N1        N2        V1        V2        Xeon       Epyc
1          30.88     32.15     33.54     32.82     27.46      8.45
2         142.56    134.48    132.01    131.50    116.68     46.53
4         310.18    282.75    287.59    271.82    251.88     86.11
8         702.02    710.29    736.72    670.63    533.46    194.60
16      1,436.17  1,684.80  1,833.69  1,782.78  1,100.15    827.28
24      2,185.55  2,508.86  2,732.22  2,815.26  1,646.09  1,530.28
32      2,942.48  3,432.84  3,643.64  3,782.23  2,236.81  2,278.52
48      4,466.56  5,174.72  5,401.95  5,621.41  4,926.30  3,026.58

The microbenchmark is repeatedly calling a small native method, so the timings demonstrate the worst case. With perfect 
scaling, the timing should be the same for 48 threads on 48 cores as it is for 1 thread on 1 core.

The solution I came up with is here: https://github.com/openjdk/jdk/pull/28575
It was suggested that it would have been better to have first discussed the issue here, but it was useful me to try and 
solve the issue first in order to understand the code.

The fundamental issue is producing a counter that can scale while ensuring races between acquires and closes behave 
correctly. To address this, I opted to use multiple counters, with at least as many counters as there are CPUs on the 
machine. The current thread's hashcode is used to select a counter. The counters are allocated in an AtomicIntegerArray, 
and are spaced such that they lie on their own cache-line.

The API has been changed such that acquire0 returns an int  - a ticket that needs to be passed to the corresponding 
release0(int) method. This was necessary as there is code where they are executed on separate threads, which would 
results in separate counters being incremented then decremented. The changes are quite widespread because of this.
If the original release0() method is kept, and the counter recalculated instead of being passed as a ticket, there are 
fewer changes, but perhaps an increased risk of bugs being introduced.

The SharedSession.justClose() method will either successfully close and racing acquires will fail, or vice-verse. In 
order to do this, there are two phases, such that the counters are put into a "closing" state if they can. Racing 
acquires will spin on this state. If the close comes across an counter in use, it will set the counters in the "closing" 
state to open, and then fail. Otherwise all of the counters in "closing" state are committed to "closed" state and any 
threads spinning in "acquire" will receive the IllegalStateException indicating that the SharedSession have been closed.

The PR above produces the following results on the same benchmark and machines:

Threads    N1      N2        V1        V2        Xeon      Epyc
1          32.41   32.11     34.43     31.32     27.94     9.82
2          32.64   33.72     35.11     31.30     28.02     9.81
4          32.71   36.84     34.67     31.35     28.12    10.49
8          58.22   31.60     36.87     31.72     47.09    16.52
16         70.15   47.76     52.37     47.26     70.91    14.53
24         77.38   78.14     81.67     71.98     87.20    21.70
32         87.54   98.01     84.73     86.79    109.25    22.65
48        121.54  128.14    120.51    104.35    175.08    26.85

In a more complex workload, we were seeing up to 3x better performance, rather than 40x as contention will typically be 
lower than that in the microbenchmark presented here.

The PR changes code quite outside its immediate area, and adds some complexity, different timing and more memory 
overhead, particularly on machines with large core counts. There is also a reliance of the threads involved hashing well 
to avoid contention. Closing may also take more time on machines with large core-counts. I wouldn't anticipate threads 
spinning in acquire0 during closing to be an issue as well-written programs should close when the SharedSession is 
unused. There is a small cost in the uncontended, single threaded benchmark on the order or 1-2ns.

Programmer's might instead be advised to use Shared.ofAuto() if contention is the biggest issue, however this may 
introduce a delay when freeing resources.


In terms of alternatives in the literature, there is the paper "Scalable Reader-Writer Locks" (Lev, Luchangco, 
Olszewski, 2009) introduces C-SNZI, which has the concept of a "Closeable, Scalable Non-Zero Indicator". It does require 
more complex data-structures that have to be traversed in a fashion that may be slower than the SharedSession 
implemention today.

I look forward to hearing peoples thoughts.

Hi Stuart,
I believe your suggested approach is a good idea to consider. Splitting 
the acquire/release counters seems like a good idea and one that, to 
some extent, as also been used elsewhere (e.g. LongAdder, 
ConcurrentHashMap) to improve throughput under contention.

The "tricky bit" is to make sure we can do all this while retaining 
correctness, as this is an already very tricky part of the code.

In the next few weeks we'll look at the code you wrote in more details 
and try to flesh out potential issues.

This problem is quite similar to a read/write lock scenario (as you also 
mention):

* the threads doing the acquires/release are effectively expressing a 
desire to "read" a segment in a given piece of code. So, multiple 
readers can co-exist.
* the thread doing the close is effectively expressing a desire to 
"write" the segment -- so it should only be allowed to do so when 
there's no readers.

In principle, something like this

https://docs.oracle.com/en/java/javase/25/docs/api//java.base/java/util/concurrent/locks/StampedLock.html

Should work quite well for this use cases. Or, even using a LongAdder as 
an acquire/release counter:

https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/concurrent/atomic/LongAdder.html

Note the javadoc on this class:

 >This class is usually preferable to |AtomicLong| 
<https://docs.oracle.com/en/java/javase/25/docs/api/java.base/java/util/concurrent/atomic/AtomicLong.html> 
when multiple threads update a common sum that is used for purposes such 
as collecting statistics, not for fine-grained synchronization control. 
Under low update contention, the two classes have similar 
characteristics. But under high contention, expected throughput of this 
class is significantly higher, at the expense of higher space consumption.

This should in principle guarantee superior performance under contention 
(similar to what you did). But, no matter the road taken, doing so 
requires separating the liveness bit from the acquire count -- and 
that's what need to be analyzed more carefully (e.g. this means making 
the acquire fail when the segment is closed, or about to be closed).

Thanks!
Maurizio

Yes, the heart of the issue is maintaining correctness while scaling. My compromise was to produce something that had a 
resemblance to transaction memory, recognising that accounting for the state of multiple counters necessarily is spread 
through multiple memory operation.

I experimented with StampedLock, but found that it scaled more or less the same as the existing implementation. 
acquire0() calls tryReadLock(), release0() calling tryUnlockRead() and justClose() calling tryWriteLock(). It appears 
the compare-and-swap operation is a bottleneck.

I found LongAdder/Striped64 interesting as, if necessary, we could look at how it is handling memory. The SharedSession 
code I wrote allocates memory upfront, such that a scenario with one thread would use as much memory as when there are 
128 threads on 128 cores. But besides that, getting the sum is not atomic, and neither is acting upon it. I experimented 
with  AtomicLong, with a close operation subtracting a very large value to force the counter negative, but that wasn't 
too different from before, dependent on atomic reads/writes to a single memory location.

Indeed, atomically setting the count and liveness is really the issue - you can't atomically check and set the sum from 
LongAdder.

Yeah --- after I sent the message I realized that sum() is good enough 
for ensuring e.g. that when closing there's no pending acquire -- but 
not for the opposite: e.g. ensuring that acquire can't happen during a 
close... so it's weaker than a RW lock (but the internals use some 
redundancy to reduce contention, which is kind of what you also do here).

For the purpose of implementation clarity -- would it be useful to wrap 
the various counters plus logic to acquire/release (and "closing" state) 
into a separate abstraction, which is then used by SharedMemorySession? 
A sort of "atomic" LongAdder, if you will :-)

That might make it easier to verify the correctness of the 
implementation, by validating each aspect (the atomic long adder, and 
its use from SharedMemorySession) separately.

Cheers
Maurizio

sum() is really just a snapshot, it adds up the counters (Cells), so it wouldn't ensure the counter was at zero. 
Immediately after returning zero a thread could have already incremented it.

Striped64 uses JavaUtilConcurrentTLRAccess to get random number, which could be an improvement over using Thread.hashCode().

Yes. What I mean is: you can check if close() should throw because of 
pending acquires. But, as I said, we can use that in any way to "block" 
other acquires from happening in case we _do_ want to close. Which 
leaves us exposed.

For what it's worth, in Netty we implement our reference counting with
incrementing by 2 instead of 1, and use the low odd bit to indicate the
released state.
This allows us to acquire using getAndAdd, which scales much better than a
CAS loop.
Unfortunately we still need to use a CAS loop when implementing release, so
that still has contention problems.

Thanks Chris,
	I've taken a look and implemented SharedSession with something similar to your RefCnt. One of the differences with 
SharedSession is that we have a separate close method. I can implement acquire0 with getAndAdd(2), release0 with 
getAndAdd(-2) and close with compareAndSwap(0, 1). With the additional tests against 0x80000001 for acquire0 and 
release0, I have something that passes the unit tests for java/foreign.

The benchmarking is quite promising, but I'll need to look more closely at it - it doesn't scale better on all platforms.

Thanks,
	Stuart

What I like (a lot) about this is that now we're back to using the same 
"bit" of information for both liveness and acquire count (IIUC). If 
that's the case, it would be much simpler to convince ourselves this is 
correct.

Thanks
Maurizio

Yeah, we previously also tried split counting, but reverted it because we
observed some weird rare issues, and got suspicious of it.

What I'm finding with the getAndAdd version is there is often an improvement, but the split counting, the multicounting 
as I called it, is much better in terms of performance (I'll share them in a week). I've tried to avoid weird issues 
with the split counting by having the code as simple as I could make it. Keeping the states consistent is important - if 
the code is in the middle of closing, it is important that getting the state of the counter pauses while that is decided.

BR,
	Stuart

Another possibility would be to split the 64 bit state into, say 8-bit 
words.

Each word would act as a counter (up to 256 acquires, theoretically).

This would allow acquire/release/close to work on different parts of the 
state field (e.g. by issuing a byte-level CAS at the correct offset), 
while still allowing the close operation to atomically CAS the entire 
counter.

But, I'm not sure this would allow for better contention, as I'd assume 
that byte-level CAS will probably translate to a 64-bit CAS with some 
extra bit masking logic on top...

There's also plenty of literarure around a multi-word CAS (MCAS) that 
feature the "disjoint-access parallel" property you want -- example

https://arxiv.org/pdf/2008.02527

They all seem to split the work in two phases:

* first, they create a descriptor for the MCAS operation they want to 
perform, and atomically set (with CAS) that into each memory address 
affected by the MCAS operation
* _after_ all affected locations have been correctly acquired with the 
same descriptor, we proceed to actually perform the desired CAS on all 
of them

This is general, but also very complex, as now we need some logic to 
allocate new descriptors and deallocate them when no longer needed -- 
which likely undoes any speedup achieved by using this more complex 
algorithm.

Of course we can take inspiration from this -- the closing thread could 
use a special value to signal that he wants to "own" all the counters 
(this can be done with a CAS from the expected non-acquired value to the 
special value).

Only if the closing thread manages to successfully set this special 
values on all the counters will it proceed to close the arena.

If something went wrong, and the special value cannot be set on some 
counters, the close fails (that means some acquire operation managed to 
sneak in between), and the counter state has to be reset for all the 
updated couters.

(perhaps this same logic can also be used to avoid close vs. close 
races, as one of the closing thread will see some counters _already_ in 
the special state, which means some other thread is attempting to close).

This seems quite similar to the approach Stuart tried to implement here:

https://github.com/openjdk/jdk/pull/28575

Maurizio

Hello Maurizio,
	My expectation is that while a compare-and-swap would operate correctly on an individual byte, the contention would 
still be operating at a cache-line granularity - at the very least there would be queuing of some sort on a CAS on the 
individual bytes of the same 64-bit word.

BR,
	Staurt

In our case, we'd be setting one word in acquire0/release0. Only the justClose0 method would acquire all of the 
counters. For Java, I'd expect we'd be operating on arrays of objects - we're not going to swap longs and Object 
references - maybe autoboxed Integers and WordDescriptors. This would change the common case of an load and a CAS to 
something more complex involving an allocation and multiple additional stores and loads.

That is my concern - allocating before you even begin to increment/decrement a counter is going to be costly. There are 
also the levels of indirection this would involve. Having threads help other threads progress is interesting, but in 
this instance, we really are just incrementing/decrementing counters - by the time you've checked if you ought to help, 
I suspect it's better to just retry.

In the PR the special value is -1 "CNT_CLOSING", which isn't help in a separate state, but in each counter. I suppose it 
is possible to have a separate value (perhaps the existing MemorySessionImpl.state variable), but that would add an 
additional read to acquire0. It would be an alternative way of controlling concurrent calls to justClose() which I 
worked around by making the method synchronized. I considered using java.util.concurrent.locks.ReentrantLock, but there 
is unlikely to be any contention.

Having a global value might help address one concern I have, where a global counter is used in the uncontended state, 
but that is changed to indicate when the state is contended and the multiple counters have been allocated and used 
instead. I haven't prototyped such a thing yet - someone would have to win the race to perform the expansion, and 
managing the counters when a global counter is >0 would be tricky - I suspect the transition would need to occur if the 
counter ever transitioned back to 0. We don't have global state to place the acquire0'd counters through the expanded 
multicounters.

Yes, while setting the counters to CNT_CLOSING, acquire0 calls will spin until their counter is changes back to "0" if 
the close fails, or the acquire0 will fail if the counter is set to CNT_CLOSED. The closing thread will succeed if all 
of the counters are set from 0 to CNT_CLOSING, in which case they are set to CNT_CLOSED. Otherwise, the closing thread 
will change the counters it set from CNT_CLOSING to 0, and then fail itself. So, yes, very similar.
