Yes, it is quite integral to SOMns.
Everything executes on one of 4 fork/join pools (depending on the concurrency model).

All threads in my system are consequently subclasses of ForkJoinWorkerThread: https://github.com/smarr/SOMns/blob/master/src/tools/concurrency/TracingActivityThread.java#L16

Is there going to be an API for efficient thread-local data, too?
And if so, what’s the design going to be, roughly?

Thanks
Stefan
