Hi Moreno --
snow provides an easy interface to simple parallel types of
calculations (e.g., lapply in parallel). I quickly wanted to have more
direct control over how parallel computations were calculated, and
have been using Rmpi. Though in principle snow and Rmpi are 'easy' to
use, I found that
Dear R users,

This is probably because 'random' numbers are generated starting from

Hi Scott --
It took me a bit to figure it out, but the help page for system made
it seem like system should return the exit status, rather than the
command result, if system is invoked without specifying intern =

it's a side-effect
Hello,
I am trying to do model autocalibration using the snow and rgenoud
packages. The function I want to run in task-parallel fashion across
multiple machines is one that pre- and post-processes data and runs an

Hi Scott,
It is difficult to debug your issue without more information. Would
it be possible to email me code of a simple example?

I am trying to use the optimizing function genoud() with the snow
package on a couple of i686 machines running Redhat Linux WS4 . I don't
know anything about PVM or MPI, so I just followed the directions in

Hi, list,
Sorry if I am bothering you.
I am interested in using xgrid with R for distributed computing. I am using
MacOS X and my R 2.1. 1 is already installed and running. The client
computers are all of the same type and the same version of R has been
installed on them.
We have also set up xg

Consider using R and take a look at the SNOW package.

What about asking on s-news rather than r-help? The latter is intended
for R related questions.
