= Tiamat == Summary Automatic parallelism across multiple cores and machines: a plugin for Pure. == Synopsis require ‘tiamat/autoconfig’ require ‘benchmark’ mod = Pure.define do def total(left, right) left + right end ``` def left (1..500_000).inject(0) { |acc, n| acc + n } end def right (1..500_000).inject(0) { |acc, n| acc + n } end ``` end # compute using two threads puts Benchmark.realtime { mod.compute(2).total } # =\> 0.4432079792022705 # compute using two local Ruby interpreters Tiamat.open\_local(2) { puts Benchmark.realtime { mod.compute.total } # =\> 0.2420041561126709 } == Description Tiamat is a worker plugin for the pure functional package. It links Ruby interpreters together with DRb, forming a back-end for Pure’s parallelizing engine. == Install % gem install tiamat Or for the (non-gem) .tgz package, % ruby install.rb [–uninstall] == Links - Pure: [http://purefunctional.rubyforge.org](http://purefunctional.rubyforge.org) - Documentation: [http://tiamat.rubyforge.org](http://tiamat.rubyforge.org) - Download: [http://rubyforge.org/frs/?group\_id=9145](http://rubyforge.org/frs/?group_id=9145) - Rubyforge home: [http://rubyforge.org/projects/tiamat](http://rubyforge.org/projects/tiamat) - Repository: [GitHub - quix/tiamat: Automatic parallelism across multiple cores and machines](http://github.com/quix/tiamat) == Author - James M.

James this is wicked, love what you’re doing, although I have no idea on how to use it yet =) Does Tiamat work on top of Pure? Where should I start? – Kind Regards, Rajinder Y.

Yes, Tiamat is a back-end for Pure. The first step is to install it and then run through the examples in the readmes. Have you tried that? ---

I’ve install pure (0.2.0), however I get the following error when I try to run the 1st example from the site irb(main):001:0\> require ‘pure/dsl’ LoadError: no such file to load – pure/dsl from (irb):1:in `require’ from (irb):1 – Kind Regards, Rajinder Y.

I will play around with pure, it looks very promising even though I don’t have immediate use for it now I think it’s well worth getting to know. – Kind Regards, Rajinder Y.
