Recently I’ve learned how to do parallel computing in R on a cluster of machines thanks to the R packages snowfall, snow, and Rmpi. I’ve been using the SOCKET method with snowfall since together they make things simple. With these tools, I can reduce day/week long jobs to hours or a day across many (100)

I didn’t try it before because i didn’t have a good toy example, and it seemed like a steep learning curve (i only guessed what parallel computing was).
