Subject: [ANN] Tiamat: Automatic parallelism across multiple machines

= 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]
