Provides a parallel each that lets you enumerate using N threads. Use environment variable N to customize. Defaults to 2. Enumerable, so all the goodies come along (tho not all are wrapped yet to return another ParallelEach instance).
Create a new ParallelEach instance over
list
.
# File minitest/parallel_each.rb, line 25 def initialize list @queue = Queue.new # *sigh*... the Queue api sucks sooo much... list.each { |i| @queue << i } N.times { @queue << nil } end
# File minitest/parallel_each.rb, line 58 def count [@queue.size - N, 0].max end
Starts N threads that yield each element to your block. Joins the threads at the end.
# File minitest/parallel_each.rb, line 46 def each threads = N.times.map { Thread.new do Thread.current.abort_on_exception = true while job = @queue.pop yield job end end } threads.map(&:join) end
