[R] Parallel R for dummies (on hpc)

[Markus Schmidberger]

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

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?
