Hello Rich,
I know this is an old post, but did you consider using Terracotta
(http://www.terracotta.org/) for clustering Clojure? It might fit the
Clojure concurrency model much better than MPI, and you wouldn't have
to mix Java with Erlang (or any other external technologies). You can
already cluster other JVM based programming languages like JRuby
(http://jonasboner.com/2007/02/05/clustering-jruby-with-open-
terracotta/) or Scala (http://jonasboner.com/2008/01/25/clustering-
scala-actors-with-terracotta/).
Cheers,
Chris

it when designing Clojure. At the time, it had a problem not
preserving identity semantics for interned Strings which I believe
they have since changed.
There was a time when I had the Clojure STM running on Terracotta, not
sure if it still uses the subset of the Java lib that Terracotta
supports.
If anyone wants to do some exploring of this I'd be very interested in
the results.

Due to my interest in Erlang and functional programming in general,
for some time I have been following a blog by Jonas Bonér at
http://jonasboner.com/
This guy is an expert on Terracotta and he managed to cluster JRuby
and Scala using Terracotta (he described it on his blog). I think it
would be a good idea to talk to him and ask him for support. I am by
no means an expert on Java, not to mention Terracotta or Clojure, this
is why I haven't done it by myself. I think it would be much better if
some Clojure guru did it, but if you don't have enough time at your
disposal then I can try to talk to Jonas.

community has made a best effort with the Terracotta docs. If you're
not up to speed on TC/Java/Clojure perhaps someone else will
volunteer.

I am not very far from tackling this issue. In our bus messaging system, we are using Terracotta with some Java components
and it's a matter of weeks before we start to investigate how we can bridge Clojure and Terracotta.
A customer asked us about some new functionality today and I see a need to fill the Terracotta/Clojure gap
somehow.
I'll comeback toward the end of November with some proposal.
Any comments Rich about how you would see this integration and what Clojure semantics you would like to share through Terracotta ?
I might enlarge the scope beyond what we need in our system even if not all the pieces are delivered in the very short term.

Luc, I'm interested. How's it going?

We just started to look at the issue. Got late in the user acceptance tests because of the radiology equipment supplier
is dragging it's feet.
I feel we will start before Xmas to put together a prototype.
I really want this to come to life because we could use cooperative Clojure instances on our bus. This would also
provide us another form of persistance. Presently we rely on ActiveMq queues but to maximize parallelism we
need another model and building that from queues would be harder.
I'll keep everyone posted. As soon as I can get my hands on it without being interrupted by the current
release of our bus we launch this.
We are scheduled to go live January 5th so that's why I am struggling and pushing on that other supplier to get his act together.
Grrr ! They're big, we're small and we move 1000 times faster. It's frustrating. They need 3 people to do the job of one of us
and still they can't turn on a dime like us.
