Materials for presentation on parallel processing at spring 2015 The Hacker Within meeting at UC Berkeley, presented by Chris Paciorek.
The tutorial material is in parallel.pdf, which is created from a Sweave-based lyx/Latex file (parallel.lyx / parallel.Rnw) using the knitr package in R:
Rscript -e "library(knitr); knit2pdf('parallel.Rnw')"
