I found this post from DecisionStats.com helpful and interesting. If you’re an R user, you might have longed for a single archive of all the HPC work around R. Pine no more, friends, for here it is.
This CRAN task view contains a list of packages, grouped by topic, that are useful for high-performance computing (HPC) with R. In this context, we are defining ‘high-performance computing’ rather loosely as just about anything related to pushing R a littler further: using compiled code, parallel computing (in both explicit and implicit modes), working with large objects as well as profiling.
Included in the list are packages that support message-passing programming in R applications, threaded programming, grid computing support, interfaces to batch schedulers, and more.
