Hello dear R-help group (and David Smith from REvolution),

I would like to perform parallel computing using R with Condor (hopefully
using foreach or other recommended solutions, if available) for some
"Embarrassingly parallel" problem.
I will start by listing what I found so far, and then go on asking for help.

So far I found the a manual by Xianhong Xie from Rnews_2005-2 (see page 13)
Talking about R and condor:
http://cran.r-project.org/doc/Rnews/Rnews_2005-2.pdf

I also found several references for R and condor in the task views of High
Performance Computing<http://cran.r-project.org/web/views/HighPerformanceComputing.html>
:
http://cran.r-project.org/web/views/HighPerformanceComputing.html
Stating that: "The
GridR<http://cran.r-project.org/web/packages/GridR/index.html> package
by Wegener et al. can be used in a grid computing environment via a web
service, via ssh or via Condor or Globus."
I then found a 2008 lecture slides on the subject here:
http://www.statistik.uni-dortmund.de/useR-2008/tutorials/GridR.pdf

And an articles showing it was already done:
http://www.ecmlpkdd2008.org/files/pdf/workshops/ubiqkd/3.pdf
(But without code examples to my dismay)



What I wish from you is some guidance.
Is there a more updated (formal) material on condor and R then Xianhong Xie
article from 2005?
Is GridR a good way of making the connection?
Is using the foreach package relevant or useful here?

I am not a UNIX person. I never ran R in "batch", and any "step by step"
instructions (either by referring to links or explaining here) would be of
great help.

Thanks in advance,
Tal
