Combining: R + Condor in 2009 ? (+foreach maybe?)
...,
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:

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>

Condor and R
...uccessfully linked R against the
Condor libraries so that R can be run as a Condor job in the
"standard" (not "vanilla") universe. The advantage of this would be
that due to checkpointing, jobs can be suspended and transferred to
another node. There is a good overview by Xianhong Xie here:
http://cran.r-project.org/doc/Rnews/Rnews_2005-2.pdf
Unfortunately, the article points out that some restrictions of
Condor preclude us from running R in the standard universe. Does
anyone know if this can be overcome?
Thanks

R and condor
Hello,
I would be extremely grateful if anyone is able to provide any (rather obscure) advice on using R with Condor. I think I'm following Xianhong Xie's instructions (R News 5(2) 13-15) correctly, but my job just stays held in the queue (for days / months). I've checked condor_status to make sure there are plenty of machines available, but can't see any way to attack the problem of the non-running jobs.
I did wonder whether I s...

Managing random number generating, while using Condor parallel computing
Hello all,
Recently I started playing with running R scripts on the Condor system in my
institute.
(For more on this, have a look at:
Running Long R Jobs with Condor DAG
by Xianhong Xie

)
Might someone advice me about the following question:
How should I handle the RNG (random number generation) in the running of
parallel instances of R on different machines.
For example, Let's say I wish to run 10 times a script...
