R help - Feb 2008 - Parallel R for dummies (on hpc)

Hi,

I had access to an hpc cluster, and wanted to parallelize some of my R code. I
looked at the snow,nws, rscalapack documentation but was unable to make out how
I should submit my job to the hpc, and how I should code a simple program. For
example, if I had 10 matrices, and 10 processor how should I write the R (and
the hpc submit code) so that I run the calculations (e.g. rowsums) for each
matrix in a different processor?

Are there any simple examples on how to go about doing this?

many thanks!

Hi Tim,

I think you should have a look at this Rmpi Tutorial
http://ace.acadiau.ca/math/ACMMaC/Rmpi/

and to Luke Tierney's webpage:
http://www.cs.uiowa.edu/~luke/R/cluster/uiowasnow.html

Best,
Markus
