Subdivide A Problem To A Pool Of Workers (No Shared Data)

Take a hard to compute problem and split it up between multiple worker threads. In your solution, try to fully utilize available cores or processors. (I'm looking at you, Python!)

Note: In this question, there should be no need for shared state between worker threads while the problem is being solved. Only after every thread completes computation are the answers recombined into a single output.

Example:

-Input-

(In python syntax)

["ab", "we", "tfe", "aoj"]

In other words, a list of random strings.

-Output-

(In python syntax)

[ ["ab", "ba", "aa", "bb", "a", "b"], ["we", "ew", "ww", "ee", "w", "e"], ...

In other words, all possible permutations of each input string are computed.
DiskEdit
ruby
array, threads, answers = ["ab", "we", "tfe", "aoj"], [], []
array.each { |word|
threads << Thread.new(word.split '' ) do |x|
answer = []
x.each { |a|
answer << a
x.each { |b| answer << [a, b].join }
}
answers << answer
end
}
threads.each {|thr| thr.join}
answers
