I'd like to announce the availability of the new "doMPI" package, a parallel backend for the "foreach" package, which acts as an adaptor to the "Rmpi" package. The package has been uploaded to CRAN and is now available. Like the "doSNOW" package, "doMPI" allows you to execute foreach loops in parallel using "Rmpi" as the underlying

??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. I launch my script with mpiexec: "C:\Program Files\Microsoft MPI\Bin\mpiexec" -n 3 "C:\Program Files\R\R-3.2.0\bin\x64\Rterm.exe" --no-save -q -f "MPI Test.r" The

hello all i am busy testing some code that will be used for parallel computations on a Moab cluster. I have written a C++ program and am linking it with R using the .C command - this works correctly. Extracts of the r code (as well as the *.sh file) is included below. I am able to run the code successfully if I remove all of the doMPI commands. i.e. outs=.C("prog1", all of the

Thank you very much Steve. Your suggestion works perfectly -- at least with doSEQ, doMC and doMPI.

This is a rather obscure question, I realize. I have written to the package author but have not heard back as of yet. I have read the README in the package, as well, but it didn't give me enough detail to diagnose the problems that I am having. (I did edit out the LAM-MPI check in zzz.R.in.) I am working to install Rmpi on top of MPICH on a beowulf cluster. Below is the output of the

Dear R yet again! I finally got the Rmpi package to install! Yay!. However, when I go into R to use it, there is an error with the dyn.load file. This should be simple (allegedly). Please help. Thanks, Sincerely, Erin mailto: hodgess at gator.uhd.edu /home/faculty/hodgess/R-2.6.0/bin [hodgess at gator bin]$ ./R CMD INSTALL Rmpi_0.5-4.tar.gz

Many thanks to Dr Yu for updating Rmpi for R 2.6.0, and for starting to make the changes to support Open MPI. I have just built the updated Debian package of Rmpi (i.e. r-cran-rmpi) under R 2.6.0 but I cannot convince myself yet whether it works or not. Simple tests work. E.g. on my Debian testing box, with Rmpi installed directly using Open Mpi 1.2.3-2 (from Debian) and using 'r' from

Hi everybody! I have the next code which makes a reduction of the *a *variable in two slaves, using the Rmpi package. library(Rmpi) mpi.spawn.Rslaves(nslaves=2) reduc<-function(){ a<-mpi.comm.rank()+2 mpi.reduce(a,type=2, op="prod") return(paste("a=",a)) } mpi.bcast.Robj2slave(reduc) mpi.remote.exec(reduc()) cat("Product: ")

Dear all, I have used the Rmpi package many times before however this time I've installed it as I always do with openMPI tar.gz file direct from the website. I'm installing on my ubuntu 8.10. Linux 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64 GNU/Linux All i get is: > library(Rmpi) Segmentation fault :~$ Which dumps me back into the shell, and doens't give me much

Hi, I've been trying here to install Rmpi on an SGI IA-64 machine with 64 processors, running SuSE Linux Enterprise Server 9, R 2.4.0 and lam-mpi 7.1.3. While I've read of similar problems on this list, I think I've got an entirely new set of error messages to contribute (see below). I'm not sure what the actual error is and what the @gprel relocation message is about. Any help

Shouldn't -n be 4 in the bsub command? One master+3 slaves. This was required for snowfall, but I think doSNOW is similar.

I have just installed Rmpi on a Suse 9.1 linux cluster with openmpi-1.0.1. I am trying the example included below from the tutorial website. However, I keep getting the following error: > # Load the R MPI package if it is not already loaded. > if (!is.loaded("mpi_initialize")) { + library("Rmpi") + } > > # Spawn as many slaves as possible >

Dear R People: Here are my latest attempts for Rmpi: This is the list of locations for mpi.h: /home/faculty/hodgess/mpich2-1.0.5p4/src/include/mpi.h /home/faculty/hodgess/include/mpi.h /home/faculty/hodgess/lam-7.1.4/romio/adio/sgi/mpi3.1/mpi.h /home/faculty/hodgess/lam-7.1.4/share/include/mpi.h /usr/src/linux-2.4.21-20.EL/drivers/addon/fusion_20505/lsi/mpi.h

Hello, I've installed R on my RHEL3 cluster and I am trying to get Rmpi to work properly. R is installed using the following ./configure --prefix=/home/apps/R-2.2.0 I installed snow using R CMD INSTALL /home/apps/snow And finaly Rmpi R CMD INSTALL /home/apps/Rmpi --configure-args=--with-mpi=/path/to/lam There were no errors or warnings upon installation.

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

Hi, I need to understand when is it best to use /rmpi/ and when is it best to use /snow/ for parallel programming in R? I understand snow can be used for a group of non-clustered work stations also. But I wish to understand from the point of view of using both on clusters for a problem which has few chunks of straightforward data-parallelism interleaved with some communication. Since both are

Hi, 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 error: MPI_Error_string: error spawning process > sessionInfo() R version 2.6.0 (2007-10-03) x86_64-unknown-linux-gnu locale:
