Erlang-style message-passing in R: Rmpi, Snow, NetWorkSpaces, etc.
I see about 7 different R packages for multi-process parallel
programming. Which do you think is the best, most complete, and most
robust to pick for general purpose Erlang-style message-passing
programming in R, and why?
First here's my use case, and then my analysis so far. I often have
code whose basic organization looks something like this:

Summary of Suggestions for poor man's parallel processing
Thanks to Luke Tierney, Agustin Lobo, Stephen Eglen, A.J. Rossini, Simon Wood
and Timothy H. Keitt for responding to my question about poor man's parallel
processing. Much of the substantive material was cc'ed to r-help already, but
my take is as follows.
1) Currently, there is nothing "simple" for solving my problem.
2) I thought that Timothy Keitt's description of the use

SNOW: Simple Parallel Computing in R
The package `snow' (Simple Network of Workstations), originally
announced in early form about a year ago on this list, is now
available from CRAN. Snow implements a simple mechanism for using a
workstation cluster for ``embarrassingly parallel'' computations in R.
The interface, which is based in part on the Python CoW (Cluster of
Workstations; http://www.scipy.org/) package, is

Viable Approach to Parallel R?
All,
We are researching approaches to parallel R with the end goal of running
R in a distributed manner on a Linux cluster. We expect of course to do
some work decomposing our problems to be task-parallel or data-parallel,
but wouldn't mind getting an initial boost working with "embarrassingly
parallel" code sections and one of the approaches below.

Problems with snow and rpvm
Dear Friends,
I'm trying to learn to use parallel computation using
snow & rpvm
Now, I have two boxes:
1) Pentium 4, pvm 3.4.5, R 2.2.0
with FreeBSD 5.4 (box uffbsd);
2) PowerPC, pvm 3.4.5, R 2.1.1 with
Debian Linux latest stable (box powerpclinux);
I'm using the

build rpvm under cygwin
I tried ot build rpvm in my own makefile.
But runs into some linker errors like e.g.
undefined reference to `_R_alloc'
My enviornment looks like this:

pvm 3.4 compiled under cygwin myself
R installed from the rw2001.exe setup file.
I guess that the R under rw2001.exe was build with
some other compiler?

R on Beowulf cluster?
Dear R-help,
Has anyone tried running R on a Beowulf-type cluster? I can get R to run in
batch (using R CMD BATCH) on a cluster, but am wondering if it is possible
to get an interactive R session on a compute node. Right now, if I run:
beorun --nolocal R
I just get the R start-up message and back to the shell prompt. If I try
bpsh 0 R
I can get R started (but the R prompt does not

rpvm/snow packages on a cluster with dual-processor machines
Hi,
does anybody know how to use the dual processors in the machines of a cluster? I am using R with rpvm and snow packages. I usually start pvm daemon and add host machines first, and then run R to start my computing work. But I find that only one processor in each machine is used in this way and the other one always stays idle. Is there any simple way to tell pvm to use the two processors at

R on a multi core unix box
Hi,
I installed the snow package on a unix box that has multiple cores. To be
able to exploit the multiple cores (on one pc) do I still need to install
the rmpi package (or rpvm). Another question, if i run a bayesian simulation
on the multiple core after setting them up correctly (using snow), would you
think there will be a noticeable speedup gain.
Thanks,
Saeed

rpvm for windows anyone ?
Dear R Users,
Is there a version of rpvm available for windows ? I have recently had
some problems with snow using SOCKS and was considering PVM as an
alternative.
Thanks in advance,

[LLVMdev] Coarse-grained parallelism
Hello,
I found some code within the pool allocation project to identify parallelizable function calls.
Unfortunately the functionality isn't part of the current release of poolalloc (in release 14 it was).
My intention is to estimate the parallelization-potential of sequential applications concerning coarse-grained parallelism.
Can you tell me...

PVM error message
Hello R enthusiasts,
I am working with a Fedora Core 6 OS and R 2.5. I have just finished
loading PVM on my test cluster and this is working properly. Also, rpvm
has been loaded in R. However, when I try to load my test program, I
receive this error:
