Concurrent GEM for Ruby ?

jamesl

Hi,

I'm wondering if anyone would like to see a Concurrent Library for
Ruby, like the Java javax.concurrent library ?

I know you can just use this library from jruby, but Im thinking more
of a idiomatic Ruby library, which could also be used ontop of jruby.

If you are interested having such a library please can you let me know
via an email to james <underscore> ladd <at> hotmail <dot> com ?

Rgs, James.

There are quite a few libraries that provide concurrency strategies already

Some building blocks are part of the standard library already: Mutex,
Monitor, MonitorMixin, Queue.

This is a public forum. Why should only you benefit from answers?

Kind regards

Well, I'm not sure what you're after. Two libraries for actor-based
concurrency (one of them mine) have been linked, but those aren't really
anything like java.util.concurrent.

Are you wanting a small framework for backgrounding work into "thread"
pools? (which would more likely be implemented as process pools)

Ruby's threads provide only sequential execution, since Ruby's memory model
is inherently sequential. For concurrent processing it's best to farm
things off to additional processes so that the OS's scheduler can make them
concurrent. There are packages to do this as well (e.g. BackgroundDRb)

If you are looking for a process pool or similar,
http://abundance.ruby...
it forks an n amount of concurrent process workers then seed/harvest them by
unix sockets communication,
