Taking R to the Limit, Part I - Parallelization in R

Tuesday night I had the opportunity to present on high performance computing in R, and the Los Angeles R Users’ Group. There was so much to talk about that I had to split my talk into two parts. The first part was parallelization and the second part will be big data (and a bit left over from parallelization including Hadoop).

My slides are posted on SlideShare, and available for download here.
