I use the snow package in R with OpenMPI and SGE quite often for my simulation studies; I’ve outlined how this can be done in the past. The ease of these methods make it so simple for me to just specify the maximum number of cores available all the time. However, unless you own your… Read more »
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)… Read more »
I finally found the time to try parallel computing in R using snowfall/snow thanks to this article in the first issue of the R Journal (replacement of R News). I didn’t try parallel computing before because I didn’t have a good toy example, and it seemed like a steep learning curve. Snow and Snowfall is… Read more »
