R on a multi core unix box
2 messages · Saeed Abu Nimeh, Luke Tierney
You can use the socket implementation of snow, with
library(snow)
cl <- makeCluster(rep("localhost", 2), type="SOCK")
to start up a cluster of 2 R processes.

Hi, I installed the snow package on a unix box that has multiple cores. To be able to exploit the multiple cores (on one pc) do I still need to install the rmpi package (or rpvm). Another question, if i run a bayesian simulation on the multiple core after setting them up correctly (using snow), would you think there will be a noticeable speedup gain. Thanks, Saeed --- linux centos 4 dual core processors 32 gb ram R (2.6.0) snow 0.29 [[alternative HTML version deleted]]
