> is there a way to parallelize ruby methods?

Have a look at ForkAndReturn [1,2]. ForkAndReturn implements a
couple of methods that simplify running a block of code in a
subprocess. The result (Ruby object or exception) of the block
will be available in the parent process.

Here's an example:

 [1, 2, 3, 4].concurrent_collect do |object|
   2*object
 end   # ===> [2, 4, 6, 8]

This runs each "2*object" in a seperate process. Hopefully, the
processes are spread over all available CPU's.
