How to run two methods in parallel ruby

Question

I have two methods. The first one remotely executes an executable and the second one stars talking with an executable. The executable is a web-service. The first step does not return the true (executed through shell) because it starts and waits for the second step. Is there a way to execute the first method and the second method in parallel?

Solution 1

Use thread.

t1 = Thread.new do
  first_method
end
second_method
t1.join

Solution 2

Besides the stock threads support I'd like to mention the great Ruby gem Parallel

It can spawn processes in parallel and utilize multiple CPUs/cores at the same time.

@HuMan It does work with #join . Just read docs what this method does ruby-doc.org/core-1.9.3/Thread.html#method-i-join
