title: online fast computation environment for ruby
body: <p>I'm writing a ruby program that need raw cpu power (I know ruby is a very bad choice for this!).. but I don't have a powerful computer, so I wanted to rent something online that you pay per hour..</p>
  
  <p>Any idea? Something simple to use yet very powerful, with multiple cores. I took a look at amazon ec2, that's a possibility. Anything else, more CPU oriented?</p>
