Hi Ignaz,

Another point that is important to me, is that Java needs to have efficient garbage collection for transient short lived data. That?s why we have generational garbage collectors that can scan a root set comprising stacks + remembered set, and then trace through the young generation without going through the old generation, which could be potentially large and have very little garbage.

Now if you have a million threads, that might start to dominate the amount of memory used in the system, and render a young generation GC give or take as inefficient as an old generation GC. ?Just? scanning the stacks suddenly becomes one of the costliest operations. Basically we would no longer have an efficient way of collecting short lived data any longer. In a language implementation like go, where there is no generational garbage collection, you would always collect the whole heap anyway, so that would not come at a cost that you are not already paying for. 

On a related note, the collectors that don?t have infrastructure for concurrent thread stack scanning would naturally have their GC pause times increased by an unacceptable amount. 

By moving not currently running thread stacks to the Java heap, we can allow the ones that are inactive and long lived to move into the old generation, and hence stop interfering with young collections. This allows the young generation collections to continue being more snappy; collecting faster and not blowing up pause times. That is rather difficult to achieve with kernel thread stacks. With a million threads running on like 8 cores or whatever, it seems likely that quite a few won?t be active immediately, and move into the old generation where they can stay out of trouble for the actively processed operations, allocating a bunch of short lived transient data.

So basically, by having user level threads, the threads themselves can move into the Java heap and play nicely with generational collectors and GC latencies, in a way that isn?t relevant for language implementations that don?t have generational GC. And generational GCs are great to have in a lot of workloads.

Hope this helps.

/Erik

Relying on virtual memory alone is insufficient. Once the memory is committed, it won?t be uncommitted, 
so usage grows, but doesn?t shrink, and all that?s done at page granularity. Once you add guard pages 
to prevent stack overflows, you?ll get close to 10GB of *committed* memory for 1M threads, and that?s 
before they do anything, and the memory would only grow monotonously from there.

Using virtual memory for a contiguous and fixed address space for each virtual thread could be doable 
once it?s managed by the runtime rather than the OS ? and so could uncommit pages promptly, albeit 
through lots of interaction with the OS, and that?s something we briefly considered, but concluded it 
isn?t a high priority, so we haven?t explored it further.

I see the general point, and agree, but to be fair, I don?t think guard pages need to be committed up-front.

Just one small nit here: this is slightly misleading because platform
thread stacks are lazily allocated. So, while platform threads cannot
shrink their stacks, they do grow them.

Hello Erik and thanks for replying,

so as far as I understand this, you are trading the higher GC pressure you  
get from copying stacks to the heap on each virtual thread switch in favor  
of shorter young gen GC run times..?

I think if you use guard pages then you can also use them to shrink the  
stacks again.

Page granularity is certainly an argument (and that is why I wrote virtual  
and kernel stacks are "roughly" of same size ;)) and it clearly depends on  
average stack sizes how big the page granularity offcuts are in relation  
to the stack size. In my experience stacks can grow quite large (> 300KB)  
- especially during classloading - but I'm sure you guys know more about  
the *average* stack sizes and those tend to be smaller.

Anyways I now have a much clearer picture of the resource consumption of  
virtual threads and the trade-offs you guys considered. Many thanks for  
your replies and I'm looking forward to trying Loom!

Hi Erik,

Sorry for chiming in. I got curious and did an experiment where I don't
pre-commit guards, instead replacing later mprotect'ing them with
committing/uncommitting. The VM handled overflows just fine. Footprint was
exactly the same as before.

So I wonder if it really matters if you pre-commit guards or not. Guards
don't seem to cost RSS either way. They cost one mapping each (which is
also a limited resource), but that's true for both variants. Am I missing
something? Apart from just saving those early mmap calls.

Thanks, Thomas

p.s. I think pre-committing is no strong guarantee either since it depends
on the kernel overcommit settings. Besides, mprotect may fail at any time
later despite pre-committing due to the number of mappings. Which is why,
curiously, protecting a page can give you an ENOMEM.

I made the logging product level and added the preempt tag for preemption, in order to find out why the Preempt.java test is failing a lot.  It seems to only be failing in the interpreter test cases.  Anyway, if performance is a concern with preemption, we can move this back to log_develop_trace.

> I made the logging product level and added the preempt tag for preemption, in order to find out why the Preempt.java test is failing a lot.

Subject: Thoughts on virtual thread pinning caused by classic synchronization
Message-ID: <CANvSZQ9zN8EfAzxyZ1DN3WAQpdtDZJTAUahrCSWnXE+wxgd-dQ@mail.gmail.com>

Hello everyone,

while experimenting with Loom (build 17-loom+7-342) we noticed that there
are a couple of JDK classes (such as PushbackInputStream, file channels,
...) that rely on classic synchronization and thus cause virtual threads to
be pinned. Third-party libraries exhibit similar behavior.

Are you planning to eventually support classic "synchronized" with Loom or
do libraries (as well as the JDK) need to migrate to lock-based concurrency?

Thanks & kind regards,
Thilo

The expectation is that Java monitors will eventually be re-implemented. 
There has been some early exploration and prototyping but we expect to 
have the limitation for at least a first release. In the mean-time, and 
where feasible and impactful, the implementation of several APIs have 
been changed to use j.u.concurrent locks so that virtual threads can 
park gracefully when doing blocking I/O. Examples include the network 
channels, sockets, and http/https protocol handlers.

The java.io APIs are problematic as they have used synchronization since 
JDK 1.0/1.1. In most cases the synchronization is not specified and not 
enforced consistently. In other cases there is a lock object exposed as 
a protected field for sub-classes. In general, most of these APIs should 
not need synchronization but there are a few exceptions (PrintStream 
intended to be written too by concurrent threads, async close, cases 
where the underlying transport is packet based, and a few 
security-sensitive scenarios where corrupting the stream is a concern). 
So we have to proceed with caution. The approach that we've taken is to 
use j.u.c. locks when not sub-classed or when sub-classes by trusted/JDK 
classes. There is still a risk that there is code in the wild that makes 
assumptions on how synchronizes on the stream but I don't think we can 
do anything about that. At some point, and probably over several 
releases, we will need to address the technical debt in this area and 
gradually remove the often-broken and unspecified synchronization.

You mentioned PushbackInputStream and you shouldn't have an issue there, 
unless you are wrapping something that is using synchronization. You 
also mentioned FileChannel - if you have concurrent threads accessing a 
file channel then they will probably be using the positional read/write 
methods that are designed to support concurrent access to different 
parts of a file.

Actually, for PushbackInputStream we see thread pinning when the wrapped
InputStream from Apache HttpComponents 5 is being closed and wants to
return the underlying connection to the connection pool (which may block):

This is using a patched HttpComponents version that replaces synchronized
with ReetrantLock (hoping to eliminate all synchronized blocks on code
paths discovered during our tests) - the original version
of org.apache.hc.core5.pool.StrictConnPool.release is synchronized.

I guess the PushbackInputStream is one of those cases that can't be easily
migrated due to the synchronized object ("this") being accessible by
subclasses.

sun.nio.ch.FileChannelImpl#write(java.nio.ByteBuffer) synchronizes on a
positionLock, so I guess your assumption is correct:

For Channels, it's an anonymous inner class.

Both could be converted to ReentrantLocks, as they are not accessible via
inheritance and thus not part of a contract, right?

What would be your recommendation? Wait until synchronized support is in
place or try to migrate problematic libraries to ReentrantLock? I
understand that the latter may not be feasible for some JDK classes due to
possible contract violations...

Thanks,
Thilo

Yes, PushbackInputStream.close invokes the close on the underlying 
stream while holding a monitor so this could be problematic. The current 
PushbackInputStream.close implementation dates from JDK 1.2 and 1998 
(JDK-4017193 if you are interested) and we've been cautious about 
changing it. There is a JEP size effort needed to re-examine and remove 
most of the unspecified and inconsistent synchronization from the 
java.io classes. We've put in workaround for the most of the common 
cases and maybe we have to give PushbackInputStream more attention. 
Thanks for brining it up, I need to think about it and see how far we 
can go without changing the behavior too much that it would break 
existing code.

This one should be okay as it's not parking. The approach taken in many 
of the file I/O operations is to temporarily increase parallelism for 
the duration of the I/O operation because it's not possible to free up 
the underlying carrier thread to do other work.

Subject: New Early Access builds
Message-ID: <f462d53f-e9a3-6a9b-6006-e963eff522d7@oracle.com>


We've pushed new builds to the Project Loom Early Access download page 
[1]. The new builds are based on JDK 18 build 9 so we are up to date 
with the main line.

The new builds include the aarch64 port, both Linux and macOS.

The only significant API change in this build is that it has the updated 
ScopeLocal API, the main change being that the inherited scope local and 
API for snapshots have been removed for now.

-Alan

Subject: Regarding project loom future timeline and other projects

Hi, Varun here

I'm a Software developer worked entirely on java ecosystem and frameworks
such as Spring MVC and Spring Boot.

I was really excited about the features project loom intends to provide
with new set of tool set for developers to build highly scalable non
blocking modern solution.

But was bit disappointed when I saw that it will not be part of jdk 17
release.

Can the team let me know the proposed  timeline of the project? And any
other future projects which are in the pipeline for making java even more
feasible for Microservices  and serverless era


Regards
Varun

Hi.
I?m happy to hear you?re excited about Project Loom, and it is always disappointing
when an anticipated feature misses a release, but luckily, we have a new release 
every six months. I don?t yet know when exactly Loom will land, but it will be
a Preview [1] feature, at first.

As for other features that can benefit "serverless? code, take a look at Class Data 
Sharing; it can greatly reduce the time-to-first-response of a cold 
application and it?s already delivered. There?s a nice introduction to CDS in this blog post: 
https://www.morling.dev/blog/building-class-data-sharing-archives-with-apache-maven/

This is exactly why we do *not* make official projections about when a 
project will be released -- because invariably these projections are 
taken as promises, and if for some reason the projection falls short, 
they are framed as broken promises.

It will be ready when its ready!

Subject: RFR: avoid extra park of vthread when using fixed thread pool
Message-ID: <XKEunw5XR2XQRWzG5A-UiPjNzWL-OBSgoUy9lbWiZNo=.a1303dc8-c23b-44f7-afc9-0f20632b6d49@github.com>

The test case of ParkWithFixedThreadPool.java create 300 virtual threads, each vthread(exclude latest vthread) park itself and unpark previous vthread. The expected result is any vthread can finish.

Running this test case in slowdebug and the test will random hang.

There are three vthreads which are vt-1, vt-2, vt-3;
(1) vt-1 take the ReentrantLock, and vt-2 try to unpark vt-1, and vt-2 fail to get ReentrantLock so it park itself( the call stack is shown below); 
(2)vt-3 unpark vt-2, and vt-2 try to get ReentrantLock again, but the ReentrantLock is still owned by vt-1, vt-2 park itself again;
(3)vt-1 release the ReentrantLock and unpark vt-2, vt-2 park itself at ParkWithFixedThreadPool.java:55, and it will never unpark.(because the unpark from vt-3 has consumed)

The reason is scheduler.execute() will try to alloc a Reentrant lock when using fix thread pool, the call stack is like:

The solution is switch back to carrier thread before call scheduler.execute();

Thanks for this issue. I think we have a regression here as unpark used to switch to the carrier to avoid parking on the virtual thread. Can you try this:


--- a/src/java.base/share/classes/java/lang/VirtualThread.java
+++ b/src/java.base/share/classes/java/lang/VirtualThread.java
@@ -664,7 +664,19 @@ class VirtualThread extends Thread {
         if (!getAndSetParkPermit(true) && Thread.currentThread() != this) {
             int s = state();
             if (s == PARKED && compareAndSetState(PARKED, RUNNABLE)) {
-                submitRunContinuation(tryPush);
+
+                if (Thread.currentThread() instanceof VirtualThread vthread) {
+                    Thread carrier = vthread.carrierThread;
+                    carrier.setCurrentThread(carrier);
+                    try {
+                        submitRunContinuation(tryPush);
+                    } finally {
+                        carrier.setCurrentThread(vthread);
+                    }
+                } else {
+                    submitRunContinuation(tryPush);
+                }
+
             } else if (s == PINNED) {
                 // signal pinned thread so that it continues
                 final ReentrantLock lock = getLock();


For the test, would you mind changing it to use try-with-resources  so that it will shutdown the thread pool even if there is an exception. 

As we're here, I should mention that it is still "TBD" if we will keep the support for custom schedulers in the first version. As you found, custom schedulers mean running arbitrary code at potentially critical points (like unparking). It might be that we need to give custom schedulers further thought before deciding whether to expose or not.

> As we're here, I should mention that it is still "TBD" if we will keep the support for custom schedulers in the first version. As you found, custom schedulers mean running arbitrary code at potentially critical points (like unparking). It might be that we need to give custom schedulers further thought before deciding whether to expose or not.

Thanks for the update. I'd like to do a bit more testing with this as I suspect it may require an update to at least one of the tests that exercises custom schedulers. Will get back to you soon on this.

Marked as reviewed by alanb (Committer).

The CustomScheduler test was indeed failing with this change but it's due to a test issue where it runs the scheduler tasks on the current thread. I've remove that case from the test so I think we are good to go now.
