Dear R Users,
I have a relatively simple rmpi question.
My configation is:
- R version 2.7.2
- rmpi 0.5-6
- Deino MPI 1.1.0
- Windows XP SP2
After succesfully spawning slaves, I am trying to assign values to
variables in the environment of each slave and run some simple calcs. This
appears to fail, as below: my assignment of value "1" to variable "a"
appears to come back

Rmpi; sample code not running, the slaves won't execute commands
Hi All,
I'm trying to parallelize some code using Rmpi and I've started with a
sample 'hello world' program that's available at
http://math.acadiau.ca/ACMMaC/Rmpi/sample.html. The code is as
follows;
# Load the R MPI package if it is not already loaded.
if (!is.loaded("mpi_initialize")) {
library("Rmpi")
}
# Spawn as many slaves as possible

Puppet error reporting
Trying to understand how puppet reports errors
Example of why I am asking the question (on a test setup environment)
Created a base-1 node
Created 2 slave nodes that inherit from base-1
Let''s call those slave1 and slave2
No errors. It all works.
Created a base-2 node
created a third slave that inherits from base-2. Let''s call that slave3

foreach hangs when using doMPI on Windows with Microsoft MPI
??I installed Microsoft MPI.
Then installed the foreach and Rmpi packages.
Then built doMPI from source.
mpi.remote.exec works.
foreach hangs with the main process and all worker processes idle.

How to use mpi.allreduce() in Rmpi?
Hi everybody!
I have the next code which makes a reduction of the *a *variable in two
slaves, using the Rmpi package.
library(Rmpi)

reduc<-function(){
a<-mpi.comm.rank()+2
mpi.reduce(a,type=2, op="prod")
return(paste("a=",a))

I am using a cluster with LAM 7.1.3/MPI 2 and R 2.6.0.
Rmpi version 0.5-5 is working very well.
Now I have tested "Rmpi 0.5-6". During spawning the Rslaves I get an

Rmpi and C Code, where to get the communicator
Hello,
I try to write parts of my code in C to accelerate the for-loops. But
basic operations I want to do in R (e.g. start cluster). My R code looks
something like this:
library(Rmpi)
mpi.spawn.Rslaves()
mpi.remote.exec(....)
dyn.load("test.so")
erg <- .Call("test", ....)
....
mpi.close.Rslaves()
mpi.quit()
And my C function looks something like this:

npRmpi trouble - mpi.comm.spawn causes segfault
Dear all,
I have a large dataset of randomly generated weighed sample for which I
wish to compute a kernel density estimate.
I have used the "np" package successfully for smaller datasets, however
for the larger ones, they take too long when
using the cross validation options for bandwidth selection ("cv.ls" or
"cv.ml"). Of course, they are much quicker with

Problem with R on dual core under Linux - can not execute mpi.spawn.Rslaves()
Hi
I am trying to utilize my dual core processor (and later a
High-performance clusters (HPC) ) by using the Rmpi, snow, snowfall,
... packages, but I am struggling at the beginning, i.e. to initialise
the "cluster" on my dual core computer. Whenever I try to initialize
it (via sfInit(parallel=TRUE, cpus=2) or mpi.spawn.Rslaves(nslaves=2)
), I get an error message:

Question on Rmpi looping
Dear R list,
In the course of learning to work with Rmpi, we are confused about a few
points. The following simple program is based on some examples we retrieved
from the web. Each slave is writing the same output line multiple times (a
multiple equal to the number of slaves). In other words, the write
statements are being executed a number of times equal to the number of
slaves.

Rmpi task-pull
Hi, I'm testing the efficiency of the Rmpi package regarding parallelization
using a cluster.
I've found and tried the task pull programming method, but even if it is
described as the best method, it seems to cause deadlock, anyone could help
me in using this method?
here is the code I've found and tried:

[R-sig-hpc] Error in makeMPIcluster(spec, ...): how to get a minimal example for parallel computing with doSNOW to run?
Shouldn't -n be 4 in the bsub command?
One master+3 slaves. This was required for snowfall, but I think doSNOW
is similar.
Hope it helps
