https://openjdk.org/jeps/480

  Summary: Simplify concurrent programming by introducing an API for
  structured concurrency. Structured concurrency treats groups of related
  tasks running in different threads as a single unit of work, thereby
  streamlining error handling and cancellation, improving reliability,
  and enhancing observability. This is a preview API.

Subject: Stream.parallel() Uses Virtual Threads?
Message-ID: <CALMUwcqV4uPbPfeFcO=+FbeWGKW=_MBgfb9B1RECAmOcnTFDBw@mail.gmail.com>

Does/will Stream.parallel() use virtual threads or stay with the Fork Join
common pool threads?

Let's say I have a Stream where the "loop" is I/O bound.  Here is an
example.

list.
   stream().
   parallel().
   map(MyClass::ioBoundOperation).
   ...

In Java 8, 11, and other pre-Java 21 versions, parallel() would use the
Fork Join common pool to execute ioBoundOperation() in multiple threads.
If the list has many elements, then the Fork Join common pool will run out
of threads since there are roughly N threads where N = the number of
vCPUs.  Other parallel streams will then have to wait.  I hope I captured
the situation correctly.

If parallel() uses virtual threads, then multiple parallel streams can
execute and they won't block each other since the number of virtual threads
can be very large.

Let's say parallel() uses virtual threads, would it make sense to always
use parallel()?  I guess there is some small overhead for creating a
virtual thread.  So, processing a small list with short CPU-bound
operations may take more time than it saves.

think it would make sense in general.

Have you looked at Gatherers for doing intermediate operations yet? One 
of the built-ins is mapConcurrent [1] so in your example you could 
replace parallel().map(MyClass:ioBoundOperation) with 
mapConcurrent(MyClass:ioBoundOperation) and have the mapping function 
for each element run in its own virtual thread.

Hi,

As I have spent a fair amount of time thinking about this topic specifically, there's a lot of nuance to what it *means* to back parallel streams with VirtualThreads.

Background
Given the design of the reference implementation of java.util.stream.Stream, in parallel mode the stream pipeline is split up into segments ending with an operation which needs to run to completion, collecting its output as the input for the next segment of the pipeline. That parallelization is using customized implementations of CountedCompleters to literally (Spliterator) split the workload amongst a constructed tree of tasks.

CountedCompleters are specialized implementations of ForkJoinTasks (https://docs.oracle.com/en/java/javase/21/docs/api/java.base/java/util/concurrent/CountedCompleter.html ) and enjoy a bit of support from ForkJoinPool (ex:https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/util/concurrent/ForkJoinPool.java#L1561)

On the topic of VirtualThread
With that said, backing parallel streams with VirtualThreads would entail a lot of work to reimplement every bespoke CountedCompleter-based operation in parallel streams to perform the equivalent coordination of result completion to achieve the same performance profile as current CPU-bound workloads using parallel streams.
There's also no real reason to believe it would provide any significant benefit on a per-workload basis.

For IO-bound workloads the situation is somewhat different, because they are often subject to externally-imposed sources of stalls. However, my experience tells me that the areas of IO are often well-understood and typically limited to specific points in a pipeline (usually Input near the beginning, and Output near the end, but there are also cases where you might have request-response-style operations somewhere in the middle).

For that case, as Alan mentioned previously, Gatherers (Preview feature) offers a mapConcurrent(maxConcurrency, io-function)<https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/util/stream/Gatherers.html#mapConcurrent(int,java.util.function.Function)> which will preserve ordering of elements in the stream, and execute the supplied function inside a VirtualThread up to the configured concurrency limit, and supports cancellation of tasks in the event of short-circuiting.

If you have any opportunity to test this functionality, your feedback would be much appreciated.
Gatherers (Java SE 22 &amp; JDK 22)<https://docs.oracle.com/en/java/javase/22/docs/api/java.base/java/util/stream/Gatherers.html#mapConcurrent(int,java.util.function.Function)>

Subject: Resource Constrained Thread Per Task Executor
Message-ID: <CY8PR11MB7897C1B9F8D699FA96EE5670EEE22@CY8PR11MB7897.namprd11.prod.outlook.com>

Hello,

I have been experimenting with Virtual Threads in a Spring Integration project that is essentially a producer consumer project. it has a small number of threads that reads from an external queue (pubsub) and passes the received message off to an ThreadPerTaskExecutor executor service. It then executes several IO heavy steps.

Overall Virtual threads have been amazing, before I was running with 500-600 platform threads. Switching to virtual threads has enabled me to scale 20-30% more for the same resources (CPU, Memory).

However I am running into one problem. Since this is a spring integration project I don't have a lot of control over how the work is propagated between threads. The thread that reads from the external queue runs much faster than the internal threads processing the work. When running with high load the service fails OOM because it can start 100k+ virtual threads, and more importantly those virtual threads have 100k+ messages to be processed which take up a lot of memory.

I resolved the issue by using a ThreadPoolExecutor a with small core pool but large a max pool size (1000), a virtual thread factory,  a limited size LinkedBlockingQueue and the RejectedExecutionHandler uses the spring CallerBlocksPolicy which retries to offer() the work to the executor and blocks. This causes back pressure and ensure that the service never pulls in more work than it can manage, so it no longer OOM. It has enough threads to saturate the CPU and by using virtual threads I save a lot of memory vs platform threads.

It has been suggested we use a semaphore to control flow with virtual threads instead of a Thread Pool. The best place I can think of for controlling the number of worker threads is in the Executor Service itself. So, I am investigating creating a ResourceConstrainedThreadPerTaskExecutor that will request a resource before launching a new thread. This resource could be a semaphore or even a guava ratelimiter, but I have been facing some issues. Unlike the ThreadPoolExecutor, the ThreadPerTaskExecutor does not allow you to customize it. I can not extend it, I tried to make my own ExecutorService that has a ThreadPerTaskExecutor, but the best place to check for a resource is the private Thread start(Runnable task)  method that I cant wrap. Finally I was going to borrow code from the ThreadPerTaskExecutor but it uses several jdk.internal such as ThreadContainer.

So finally my questions:


  1.
I am aware that virtual threads should not be pooled, but is it safe to hold a virtual thread for an extended period of time in a thread pool?
  2.
Is there a perfered method to customize the ThreadPerTaskExecutor?
  3.
If I write my own executor service what is the goal of  jdk.internal.ThreadContainer? Other than holding the threads, does it integrate with the JVM on a lower level?
  4.
Can I write an executor service without a ThreadContainer? Or can I use ThreadContainer, is it acceptable to use jdk.internal classes?

If this is not possible, I can modify Springs, ExecutorChannel to control the flow at a level higher, but I felt that it would be useful to have a New Thread Per Task Executor that could be throttled or limited.  Thanks for any and all comments.

I think you can simply this. You don?t need to pool the virtual threads. Just use a semaphore to control how many are running at once. You can put this behind and Executor for a standardized api

Thanks for the feedback, and I agree completely. Spring Integration takes an Executor Service so I was trying to customize the  ThreadPerTaskExecutor. Unfortunately it is closed for inheritance and uses several classes from jdk.internal.vm, so I was not sure how best to proceed. To Write a new Executor Service without a ThreadContainer, or to use jdk.internal.vm classes.

You don't actually need fancy classes from JDK to implement this
(definitely no internal ones). Though it wouldn't be bad to have a utility
for this out of the box, the implementation of such an `ExecutorService`
(if you only need an `Executor` it is even simpler) is relatively
straightforward. Assuming you already have an `ExecutorService` with a
thread per task implementation, you just have to `acquire` the semaphore
before submitting a task to the wrapped executor, and `release` it once
the submitted task completes. If you only need an `Executor` then it is
simpler, because then you just need to do this with the `execute` method,
and also in that case you might trivially replace the wrapped `Executor`
with a `ThreadFactory` and enforce a thread per task policy.

If your api takes an ExecutorService, then that is what you need to
implement and not customizing ThreadPerTaskExecutor. Just Implement
ExecutorService using a so called WrappingExecutorService which uses
delegate pattern
to offload the actual implementation to a delegate in this case
ThreadPerTaskExecutor. Only in submit methods, make sure you acquire the
semaphore before offloading to the delegate.

I may be overthink this. I was hoping for an easy way to extend the ThreadPerTaskExecutor like the ThreadPoolExecutior is extensible. But I Agree in this case that it should wrap another executor as getting threading correct is hard! For the Executor Service, Execute and Submit would he easy to manage, as it is a single task so easy to get a acquire a single resource from a semaphore. But I will need to be more careful around invokeAll and invokeAny, as I may need to acquire more permits than are available or one invoke all may block another invoke from executing in parallel. So maybe I can submit them one at time, or just go ahead and get the number of permits at once.

It is good to know that i dont need to use any jdk.internal classes. I saw both ThreadPerTaskExecutor  and ThreadPoolExecutor using ThreadContainer and i wasn't sure if it was some special class to manage threads. I can implement something without this.

Subject: Re: Resource Constrained Thread Per Task Executor

If your api takes an ExecutorService, then that is what you need to implement and not customizing ThreadPerTaskExecutor. Just Implement ExecutorService using a so called WrappingExecutorService which uses delegate pattern
to offload the actual implementation to a delegate in this case ThreadPerTaskExecutor. Only in submit methods, make sure you acquire the semaphore before offloading to the delegate.

I think you can simply this. You don?t need to pool the virtual threads. Just use a semaphore to control how many are running at once. You can put this behind and Executor for a standardized api

Hello,

I have been experimenting with Virtual Threads in a Spring Integration project that is essentially a producer consumer project. it has a small number of threads that reads from an external queue (pubsub) and passes the received message off to an ThreadPerTaskExecutor executor service. It then executes several IO heavy steps.

Overall Virtual threads have been amazing, before I was running with 500-600 platform threads. Switching to virtual threads has enabled me to scale 20-30% more for the same resources (CPU, Memory).

However I am running into one problem. Since this is a spring integration project I don't have a lot of control over how the work is propagated between threads. The thread that reads from the external queue runs much faster than the internal threads processing the work. When running with high load the service fails OOM because it can start 100k+ virtual threads, and more importantly those virtual threads have 100k+ messages to be processed which take up a lot of memory.

I resolved the issue by using a ThreadPoolExecutor a with small core pool but large a max pool size (1000), a virtual thread factory,  a limited size LinkedBlockingQueue and the RejectedExecutionHandler uses the spring CallerBlocksPolicy which retries to offer() the work to the executor and blocks. This causes back pressure and ensure that the service never pulls in more work than it can manage, so it no longer OOM. It has enough threads to saturate the CPU and by using virtual threads I save a lot of memory vs platform threads.

It has been suggested we use a semaphore to control flow with virtual threads instead of a Thread Pool. The best place I can think of for controlling the number of worker threads is in the Executor Service itself. So, I am investigating creating a ResourceConstrainedThreadPerTaskExecutor that will request a resource before launching a new thread. This resource could be a semaphore or even a guava ratelimiter, but I have been facing some issues. Unlike the ThreadPoolExecutor, the ThreadPerTaskExecutor does not allow you to customize it. I can not extend it, I tried to make my own ExecutorService that has a ThreadPerTaskExecutor, but the best place to check for a resource is the private Thread start(Runnable task)  method that I cant wrap. Finally I was going to borrow code from the ThreadPerTaskExecutor but it uses several jdk.internal such as ThreadContainer.

So finally my questions:


  1.
I am aware that virtual threads should not be pooled, but is it safe to hold a virtual thread for an extended period of time in a thread pool?
  2.
Is there a perfered method to customize the ThreadPerTaskExecutor?
  3.
If I write my own executor service what is the goal of  jdk.internal.ThreadContainer? Other than holding the threads, does it integrate with the JVM on a lower level?
  4.
Can I write an executor service without a ThreadContainer? Or can I use ThreadContainer, is it acceptable to use jdk.internal classes?

If this is not possible, I can modify Springs, ExecutorChannel to control the flow at a level higher, but I felt that it would be useful to have a New Thread Per Task Executor that could be throttled or limited.  Thanks for any and all comments.

You can't really acquire everything at once, because you might get so many
tasks that you could never fulfil such a request. That said, `invokeAll`
can simply be done by submitting all tasks one after another. Implementing
`invokeAny` well might be trickier, but I have never seen anyone ever using
it, so I wouldn't worry too much about it. But you can check
`AbstractExecutorService` for both. In fact, you can actually use it as a
base class to provide implementation for the invoke many methods.

Thanks for the idea, the AbstractExecutorService? would be a great starting place, and that means I need to implement all the shutdown logic. Which is manageable, but tricky. I guess the moral of the story is there is no easy way out of the box to implement constrained resources with new thread per task executors. I will have to write some code and reimplement some things to get what I want.


But maybe someone can answer me the question: is it safe to keep a virtual thread for an extended period of time? Maybe I can live with my ThreadPoolExecutor solution if it is safe. For my use case it works, but it isn't ideal.

Thanks all for the feedback!

This solution generalizes for other kinds of limits too. I have an
application here that does basically the same thing with a token bucket
instead of a semaphore.

If you are wrapping another `ExecutorService`, then you don't really need
to have anything special for `shutdown` and such. You just have to delegate
those calls.

As for "is it safe to keep a virtual thread for an extended period of
time": Yes, it is safe, but pooling VT defeats its purpose.

If it is safe to keep virtual threads and pool them, there is still a net benefit to pooling virtual threads. I agree a major benefits of virtual threads is that they are cheap to create, so there is no need to pool them. But the memory and performance increase even pooling is no small matter.

In my case I have 500 platform threads I am limited because my container is small and they start to use a significant portion of the memory. I switch them for 1000 virtual threads, this saves me ~ 500 mb of RAM (maybe less i didn't do the math). Between less need for context switching and more memory for garbage, I am still seeing a 20 - 30% improvements. Which even with pooled virtual threads is a big improvement.

Firstly I was hoping there was an existing solution, I googled it a while but couldn't find any specific open source packages if anyone knows any let me know, I would prefer to import something. If not I may continue my journey of writing a new ExecutorService for my use case.

I do happen to have an executor framework in which all this is trivial to
implement, because you just need to implement a single submit method, and
the rest you can get for free (as in you don't have to implement it) using
a single call: `TaskExecutors.upgradeToStoppable(executor)` (though this
returns an instance of my `TaskExecutorService` interface, but I have
bridge methods to convert that to `ExecutorService` with minimal overhead).
See
https://javadoc.io/doc/org.jtrim2/jtrim-executor/latest/jtrim.executor/org/jtrim2/executor/package-summary.html
If
you want to give it a try, you can send me a personal email, and I can
answer API specific questions.

If you use an Executor the entire code should be less than 10 lines -  then you don?t need to manage the lifecycle, etc. - all it is is a semaphore and the spawning of a new virtual thread when then the semaphore is granted.

If you need to return Futures for cancellation / results it is a bit more complicated but not much.

Thanks that would be amazing, I will take a look at your jtrim project. If I only need to implement an executor it makes it a lot simpler than needing to implement the whole ExecutorService interface! Thanks all for your feedback!

You know what, you are right. I double checked the interface that Spring Integration was expecting and it only needs a Executor, not an ExecutorService. I got mixed up and started down the wrong rabbit hole! So you are correct, I don't need to manage the lifecycle and it is a much simpler problem with maybe 10 lines of code.

If you did need to integrate a semaphore into an ExecutorService, you might
find it easier to implement a ThreadFactory, and then leverage the utility
methods in Executors to get an ExecutorService.

```

Semaphore sem = new Semaphore(permits);

ThreadFactory factory1 = Thread.ofVirtual().factory();

ThreadFactory factory2 = runnable -> {

    try {

        sem.acquire();

        return factory1.newThread(() -> {

            try {

                runnable.run();

            } finally {

                sem.release();

            }

        });

    } catch (InterruptedException ie) { // interrupted in acquire()

        Thread.currentThread().interrupt();

        throw new RuntimeException(ie);

    } catch (Throwable t) { // threw in newThread()

        sem.release();

        throw t;

    }

};

ExecutorService es = Executors.newThreadPerTaskExecutor(factory2);

Thanks for sharing that. It is a nice solution to my problem. I wouldn't have thought about having a ThreadFactory with a Semaphore for a ThreadFactory. But it looks simple and solves the problem.

  Summary: Introduce scoped values, which enable a method to share
  immutable data both with its callees within a thread, and with child
  threads. Scoped values are easier to reason about than thread-local
  variables. They also have lower space and time costs, especially
  when used together with virtual threads (JEP??444) and structured
  concurrency (JEP??480). This is a preview API.

object monitor to avoid pinning and has already released an EA version
based on JDK 23.

I would like to ask if there is any consideration to package an EA version
based on JDK 21. JDK 21 is an LTS version, and my applications are planned
to stay on this version for a longer period of time.

Thanks.

The changes to the object monitor implementation are work in progress, 
likely a release after JDK 23. So no, this isn't something for JDK 21 
update.

Alan, I think OP is asking about short term effort (current Loom repo fiber
branch) and not the long term Java object monitor implementation.

So even the short term effort won't make it into JDK 23 ?

We need the fibers branch to track main line, it work put a huge tax all 
work items if the repo were based on JDK 21.

There are 3 parts to the object monitor work. The changes for 
Object.wait aren't in the loom repo yet, should be soon, and we'll 
publish another EA build at that point.? The fork for JDK 23 is in a few 
weeks so too soon for the ongoing work here.

-Alan.

No, because an LTS service is a new(ish) kind of release train created for the sole purpose of offering a release train for applications that value stability over all else and least of all want any new features or significant enhancements. This is something that didn?t exist in the old model of releases, prior to JDK 9, where large and potentially disruptive features as well as security patches and bug fixes were mixed in different kinds of ?minor updates?, hurting those applications that needed stability. Clearly, adding a big enhancement that entails deep changes to the runtime in updates that are especially made to exclude them would defeat their only purpose.

An application that chooses to remain on an old version and use an LTS service?s updates is one that, by that very choice expresses that is not interested and/or cannot take advantage of enhancements. If an application is interested in big enhancements it can use the ?tip? version ? a model that is a little more similar to the traditional one.

Subject: Performance of pooling virtual threads vs. semaphores
Message-ID: <CAL4QsguvDZ9cBJAqk6zzg_mT1Oj4jYeSVs6mAjed0X8CpZPthg@mail.gmail.com>

Hello,

JEP 444 [1] and the docs in [2] mention that virtual threads should not be
pooled, and suggest semaphores as one possible alternative.

My colleague Chi Wang has been investigating virtual thread performance,
and has found that creating one virtual thread per task and synchronizing
on a semaphore can result in worse performance on machines with large
numbers of cores.

A benchmark run on a 128 core machine is included below. It submits
numTasks tasks to the executor determined by the strategy. The task itself
is mixed with CPU and I/O work (simulated by fibonacci and sleep). The
parallelism is set to 600 for all strategies.

* Strategy 1 is the baseline where it just submits all the tasks to a
ForkJoinPool whose pool size is 600.
* Strategy 2 uses the method suggested by JEP 444.
* Strategy 3 uses a fixed thread pool of 600 backed by virtual threads.

Note that, with 100K and 1M tasks, strategy 2 has a CPU time regression
that seems to increase with the number of cores. This result can be
reproduced on the real-world program that is being migrated to a
virtual-thread-per-task model.

Diffing the cpu profile between strategy 1 and strategy 2 showed that most
of the CPU regression comes from method
`java.util.concurrent.ForkJoinPool.scan(java.util.concurrent.ForkJoinPool$WorkQueue,
long, int)`.

Are there any ideas for why the semaphore strategy uses more CPU than
pooling virtual threads on machines with a large number of cores?

Thanks,
Liam

Subject: Performance of pooling virtual threads vs. semaphores

I don?t think this code is written correctly. With the implementation of option #2 - the system is going to create a virtual thread for every task up front, then try and schedule them on to the 128 carrier threads, then once a task runs, it is going to try and limit concurrency using a semaphore.

I think this is inverted, and you should have the Executor use the semaphore to limit the concurrent virtual thread creation in order to have similar performance.

The way it is written now, the virtual thread scheduler has to manage 1 million ?virtual? threads - versus in the native thread impl the system is only managing 600.

The reason the CPU usage is much higher is because you have the semaphore code only enabled for option 2. You should be able to create and use the semaphore in all impl to compare similar performance, PLUS the scheduler having to manage scheduling 1M threads.

To clarify, with option #2, you have potentially a million thread contention on the semaphore.

Subject: Question about StructuredTaskScope.joinUntil(Instant) 
Message-ID: <439D398A-5972-49CE-8C06-1E6E05D92E60@fibermail.ch>

Hello everyone,

I have a question about StructuredTaskScope.joinUntil(Instant).

I am implementing a solver algorithm that has an execution time limit. 
The solver spawns sub-tasks and gathers all results that have been computed within the time limit.
I made a proof-of-concept that uses StructuredTaskScope.joinUntil(Instant) to define the deadline as Instant.now().plus(30, ChronoUnit.SECONDS);


Now, I am concerned that the System clock changes unpredictably due to NTP, while the solver runs.
So that, as the solver spawns new sub-tasks, the deadline will not stay constant.

I noticed that the code in StructuredTaskScope.joinUntil(Instant) calls Instant.now() to compute a timeout for the deadline.
I tried to create a subclass that uses a Clock instance of my own that is based on an internal time source (System.nanoTime), but I could not do this, because method StructuredTaskScope.implJoin(Duration timeout) is private.

So my question is:

Is there a way to use the StructuredTaskScope deadline feature so that it does only rely on resources provided by the current process - instead of relying on System time over which the current process has no control?


With best regards,
Werner Randelshofer

Hey team,
hope you are all well

Following up on this one, I noticed that changes to the Object.wait issue
were committed few days ago, and wanted to ask how far are you from
issuing a new EA build?

We'll refresh the EA builds soon, just want to make sure the changes are 
stable before doing that.

Subject: Performance of pooling virtual threads vs. semaphores

I vaguely remember Alan or Ron saying that timed waits for VTs are not yet
as efficient as they want them to be (though I'm not sure if that is the
case for JDK 23 still). So, I would expect that the major performance
difference you are seeing might be because of the sleep calls (and in
realistic scenarios, I'm guessing the same would be true for other timed
waits).

I remember that too, but in this case I don?t think it is the cause.

In the bounded/pooled thread scenario - you are only scheduling 600 threads (either platform or virtual).

In ?scenario #2? all 1M virtual threads are created and are contending on a sempahore. This contention on a single resource does not occur in the other scenarios - this will lead to thrashing of the scheduler.

I suspect if it is run under a profiler it will be obvious. With 128 carrier threads, you have increased the contention over a typical machine by an order of magnitude.

Actually, I take back what I wrote, because whatever cost the timed wait
has shouldn't be more effort when there are 1M concurrent threads, than
when there are 10k, since there can be only at most 600 threads in
timed wait. It is certainly interesting, because I would also not expect
`VirtualThreads.unpark` to be so much worse with a larger queue (in fact I
wouldn't really expect it to be pretty much any worse). Hopefully Ron or
Alan can make better guesses (or not guesses).

Yeah, just realized that and sent my email pretty much literally a second
after your email :)

Anyway, while yes in theory 1M threads are contending for the semaphore,
but I don't think that should be a problem, because the contention is
rather theoretical, since those "contending" VTs are just sitting in a
queue, and after each release only one of them should be released. Also, I
think Liam's comparison is fair, because none of the other two methods push
back, so pushing back only in the VT version would be very unfair.

But looking at the numbers some more they don?t make sense. The total times go way down, moving from 10_000 tasks to 100_000 tasks. Then they go up again (expected) moving from 100_000 to 1_000_000

I don?t think the wall time should ever go down when the number of tasks go up, so something doesn?t seem right.

Ignore that - the first set of metrics are in ms.

But the wall time within a numTasks is nearly identical regardless of scenario.

You can see from the flame graph that the system is spending all of its time scheduling VTs and sleeping - the ?work? is negligible. The is the carrier thread on my system with the most ?work? (execute()) - most of the carrier threads are doing no work at all. Every carrier is spending its time going to sleep and waking back up.

I am guessing the JVM is optimizing away the call to fibonacci() since the results are not used, so all the tasks are doing are sleeping and waking up.

Not a good test.

If the concurrency for the virtual thread run is limited to the same 
value as the thread count in the thread pool runs then you are unlikely 
to see benefit. The increased CPU time probably isn't too surprising 
either. In the two runs with threads then the N task are queued once. In 
the virtual thread run then the tasks for the N virtual threads may be 
queued up to 4 times, one for the initial submit, one waiting for 
semaphore permit, and twice for the two sleeps. Also when CPU 
utilization is low (as I assume it is here) then the FJP scan does tend 
up to show up in profiles.

Has Chi looked into increasing the concurrency so that it's not limited 
to 600? Concurrency may need limited at finer grain the "real world 
program", but may not the number of threads.

Though the additional work the VT has to do is understandable. However, I
don't see them explaining these measurements. Because in the case of 10k
tasks VT wins over FJP, but with 1M tasks, VT loses to FJP. What is the
source of the scaling difference, when there are still only 128 carriers,
and 600 concurrent threads in both cases? If this was merely more work,
then I would expect to see the same relative difference between FJP and VT
when there are 10k tasks and when there are 1M tasks. Just a wild naive
guess: Could the GC scale worse for that many VTs, or is that a stupid idea?

That is what I pointed out - in scenario 2 you are creating 1M VT up front. The other cases only create at most 600 VT or platform threads. 

The peak memory usage in scenario 2 is much much higher.

They only create 600 VT, but they do create 1M queue entries for the
executor, and the relative memory usage should be the same for the scenario
of 10k tasks and the 1M (both in terms of bytes and number of objects). I
would love to see the result of this experiment with the epsilon GC (given
that the total memory usage should be manageable even for 1M tasks) to
confirm or exclude the possibility of the GC scaling this noticeably poorly.

A small correction: "They only create 600 VT" should be platform thread,
not VT of course for the fork join pool.

Also note: That the scaling difference between option 3 and option 2 is not
large. If it was simply the problem with creating more VTs upfront, then we
would have to see a similar increase in difference between case 3 and 2.

Reworking the design (scenario 4) brings the pooling and new VT per task in line:

iMac:vt_test robertengels$ time java -Djdk.virtualThreadScheduler.parallelism=128 Main dummy 2 1000000

real	0m38.405s
user	3m42.240s
sys	0m12.976s

iMac:vt_test robertengels$ time java -Djdk.virtualThreadScheduler.parallelism=128 Main dummy 3 1000000

real	0m37.710s
user	2m28.901s
sys	0m3.427s

iMac:vt_test robertengels$ time java -Djdk.virtualThreadScheduler.parallelism=128 Main dummy 4 1000000

real	0m38.441s
user	2m39.547s
sys	0m7.027s

My machine only has 8 real cores, so I expect greater system cpu usage due to kernel thread scheduling. There is also the additional semaphore management.

In scenario 2, the system is starting and scheduling all 1 million threads, just to have them go park, waiting on the semaphore, then to be woken up and rescheduled. This is not insignificant. Scenario 4 avoid this.

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.ForkJoinPool;
import java.util.concurrent.Semaphore;
import java.util.concurrent.ThreadFactory;

public class Main {

  private static Semaphore semaphore = null;
  private static int sink = 0;

  public static void main(String[] args) {
    int strategy = 0;
    int parallelism = 600;
    int numTasks = 10000;

    if (args.length > 1) {
      strategy = Integer.parseInt(args[1]);
    }

    if (args.length > 2) {
      numTasks = Integer.parseInt(args[2]);
    }

    ExecutorService executor;
    switch (strategy) {
      case 1 -> {
        executor = new ForkJoinPool(parallelism);
      }
      case 2 -> {
        executor = Executors.newVirtualThreadPerTaskExecutor();
        semaphore = new Semaphore(parallelism);
      }
      case 3 -> {
        executor = Executors.newFixedThreadPool(parallelism, Thread.ofVirtual().factory());
      }
      case 4 -> {
        var factorySem = new Semaphore(parallelism);
        ThreadFactory tf = (Runnable r) -> {

As a somewhat important aside, I am guessing based on the original reported timings, that it is not a real 128 core machine. It is most likely 128 virtual cores, and probably shared. I don?t think you should be performing CPU benchmarks in those environments. The fact that my 8 core machine (only 4 real cores) is outperforming a 128 core machine is not a good sign.

Your case 4 is unfair. It doesn't have the same behavior as the other 3,
because you are pushing back (i.e., you are limiting the task producer
thread) which is of course more efficient. Even though pushing back is
normally necessary in real world code, you are just simply measuring
something different, and I suppose the question is not how to make this
code faster, but why case 2 scales so weirdly with the number of tasks
compared to the other two scenarios.

Also, I might be misreading something, but you are not outperforming the
reported numbers. You are about 4s slower. FYI: Liam had the CPU near the
end of his email: "AMD Ryzen Threadripper PRO 3995WX" (64 real cores).

A minor rework would fix that - but the ThreadPerTaskExecutor is not public, so it would have been more work. The total task submission time is insignificant - that is not the issue. It is only added an entry per task to concurrent linked list.

My tests are easily outperforming if I only have 4 cores and the reporter has 64 - on an ops per cpu basis. The OP also states: "A benchmark run on a 128 core machine is included below.? So, it may be 64, but it probably has dual hardware threads. Also, look at the user and system cpu times - those are more important than wall time if you are attempting to look at efficiency of schedulers. My reported times are way lower across every scenario - which is why it appears something else may be affecting the OP?s testing.

Attached is a version that doesn?t throttle the submitter (it is not fully correct but enough for testing). It is better than scenario 2, not as good as 3. The increased number of carrier threads (without cores) hurts performance - as is expected. I would guess if the OP tries scenario 4 on his test machine, it will perform similar to scenario 3.

I would love to see the result of this experiment with the epsilon GC (given that the total memory usage should be manageable even for 1M tasks) to confirm or exclude the possibility of the GC scaling this noticeably poorly.

Because in the case of 10k tasks VT wins over FJP, but with 1M tasks, VT loses to FJP. What is the source of the scaling difference, when there are still only 128 carriers, and 600 concurrent threads in both cases? If this was merely more work, then I would expect to see the same relative difference between FJP and VT when there are 10k tasks and when there are 1M tasks. Just a wild naive guess: Could the GC scale worse for that many VTs, or is that a stupid idea?

My first guess would be that what?s being compared here is not the same algorithm. In strategy 2, you spawn a bunch of different threads that do a tiny bit of work before starting the task, while in the other strategies the algorithm is different.

In a realistic workload you will have a number of threads serving requests, and then they may want to access a concurrency-limited resource. I think you can try to simulate that by simulating, say, 1000 tasks running in some large thread pool and then each of them would submit one subtasks to a fixed thread pool of size 10. For virtual threads, have 1000 virtual threads that try to acquire a semaphore with 10 leases.

Can you try that? At least then we?ll be comparing oranges to oranges.

Subject: New EA builds with changes to object monitor implementation to avoid
 pinning with virtual threads
Message-ID: <c674ee8a-e487-4c63-bf95-b4ac9acf6f8f@oracle.com>


We've published new early-access builds from the loom repo [1] with the 
latest changes to the object monitor implementation. The changes means 
that virtual threads don't pin their carrier when parking (doing socket 
I/O for example) while in a synchronized method, blocking entering a 
synchronized method/statement because the object's associated monitor is 
held by another thread, or Object.wait. The changes for 
Object.wait/timed-wait is the main change since the previous EA.

As before, we would like to get help to test the changes. Testing the 
changes means trying out the builds with code that you know is using 
virtual threads and with libraries that are "very synchronized". We need 
to gauge both reliability and performance. Right now, the focus is on 
being functional and reliable, the performance for some cases isn't on 
par right now with blocking on j.u.concurrent locks + condition objects. 
The simplest way to report an issue or feedback is to just send a mail 
here.

As before, JFR events can be used to identify remaining cases of 
pinning, parking or blocking in a class initializer for example. The 
system property jdk.tracePinnedThreads to get stack traces when threads 
are pinned no longer prints anything.

That said, `invokeAll` can simply be done by submitting all tasks one after another. Implementing `invokeAny` well might be trickier, but I have never seen anyone ever using it, so I wouldn't worry too much about it. But you can check `AbstractExecutorService` for both. In fact, you can actually use it as a base class to provide implementation for the invoke many methods.

But I Agree in this case that it should wrap another executor as getting threading correct is hard! For the Executor Service, Execute and Submit would he easy to manage, as it is a single task so easy to get a acquire a single resource from a semaphore. But I will need to be more careful around invokeAll and invokeAny, as I may need to acquire more permits than are available or one invoke all may block another invoke from executing in parallel. So maybe I can submit them one at time, or just go ahead and get the number of permits at once.

Subject: Virtual threads and File IO
Message-ID: <C321304A-4A3C-483F-878E-FB254A631CA3@me.com>

Hi,

An interesting question came up on the Go support channels. One of the principle engineers stated that for local file IO, the Go routine (similar to virtual thread) won?t release the carrier thread.

Is this the same with Java virtual threads? Yes, local IO is typically fast - but it is still order of magnitudes slower than memory computations - which the virtual thread could be doing while waiting for the IO request to be serviced.

I looked into the code. Seems Java is the same. I looked into it - and seems for many workloads async file IO can improve efficiency by 80%.
