I've tweaked Rmpi and want to have some variables that hold data in the package. One of the R files starts mpi.isend.obj <- vector("list", 500) #mpi.request.maxsize()) mpi.isend.inuse <- rep(FALSE, 500) #mpi.request.maxsize()) and then functions update those variables with <<-. When run:

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

Can anyone help me understand how I got 2 versions of the same library loaded, how to prevent it, and what the consequences are? Running under Debian GNU/Linux squeeze. lsof and /proc/xxx/map both show 2 copies of several libraries loaded: /home/ross/install/lib/libmpi.so.1.3.0 /home/ross/install/lib/libopen-pal.so.6.1.0 /home/ross/install/lib/libopen-rte.so.7.0.0

I am running R 2.7.0 on a Suse 9.1 linux cluster with a job scheduler dispatching jobs and openmpi-1.0.1. I have tried running one of the examples at http://ace.acadiau.ca/math/ACMMaC/Rmpi/examples.html in Rmpi and they seem to be working, except mpi.close.Rslaves() hangs. The slaves are closed, but the master doesn't finish its script. Below is the example script and the call to R. The job is

Rmpi is not currently available on CRAN, and I don't think it has been for a few months. It is available at http://www.stats.uwo.ca/faculty/yu/Rmpi/ Does anyone know its current status? A few months ago I corresponded with the author, who noted some build problems (specifically on Debian) were the hang up, and seemed to be working on it. I wasn't able to get it to work then (on a

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: # Initialize MPI library("Rmpi") # Notice we just say "give us

Has anybody tried to use Rmpi with the OpenMPI library instead of LAM/MPI? LAM appears to be somewhat hardcoded in the Rmpi setup. Before I start to experiment with changing this, has anybody else tried Rmpi with non-LAM MPI implementations?

I just had the interesting experience of building a package and R on the same system, and having R refuse to load the resultant dynamic library because it was thought to be for a different system. The system was non-standard and beta, being a Linux-based 64 bit Opteron system. It uses the gnu tool chain. The dynamic library was built from C source. When I tried to load the library R (1.8.1)

Some packages are available in cran2deb and Debian. After adding cran2deb to my sources.list it seems the cran2deb ones are favored because X.Y-ZcranN is "more recent" than X.Y-Z. In the case of r-cran-rmpi the effect of this was to cause aptitude to want to uninstall all my mpi stuff. Apparently the automatically generated package doesn't have mpi as a dependency. I just put a

R objects can disappear if they are garbage collected; can they move, i.e., change their location in memory? I don't see any indication this might happen in "Writing R Extensions" or "R Internals". But I'd like to be sure. Context: Rmpi serializes objects in raw vectors for transmission by mpi. Some send operations (isend) return before transmission is complete and

Dear R People: I'm having some trouble with mpiexec and Rmpi. I would like to be able to pass in the number of "children" via the mpiexec command (from the command line). this is in SUSE10.1, with R-2.7.1 Here are my files: cat eb.R library(Rmpi) mpi.remote.exec(paste("i am",mpi.comm.rank(),"of",mpi.comm.size())) mpi.quit() hodgesse at

Although this query was inspired by distributed random number generation, one of the questions (#2 below) is a single-machine issue. I call C++ code from R to generate simulated data. I'm doing this on a cluster, and use rmpi and rsprng. While rsprng randomizes R-level random numbers (e.g., from runif), it has no effect on the C code, which is completely SPRNG and MPI ignorant. Currently I

Dear R People: I'm running Rmpi on a single machine and I have the following statement from the command line: mpirun -np 3 ./R --no-save < eek1.in >stuff4.out The stuff4.out file only contains the third result. Is there a way to fix this such that it shows all 3 sets, please Thanks in advance, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical

I'm invoking R from withing a shell script like this R --no-save --no-restore --gui=none > `hostname` 2>&1 <<BYE # various commands here BYE I would like to regain control from the invoking terminal at some point. I tried source(stdin()) but got a syntax error, presumably stdin is the little shell here snippet (the part between <<BYE and BYE). Is there some way to

After several trial and error attempts, I managed to install the Rmpi package without error on my Linux machine, running Fedora 5. I installed lam-7.1.2, lam-devel-7.1.2 and R-2.4.1, R-devel-2.4.1 The Package Rmpi_5.0-3.tar.gz, I installed once from within R and once from the command line to make sure, I link the right libraries: R CMD INSTALL Rmpi_5.0-3.tar.gz

Hello everybody, I am trying to install Rmpi on 64-bit HP-Proliant server. I am facing the following error: * Installing *source* package 'Rmpi' ... Try to find 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. However when i perform the test

I am working on a SLES 10 cluster with R available on it. To better use my resources, I want to use Rmpi, but I am having a difficult time installing it. I have set the $R_LIBS variable correctly. The MPI libraries are available through the PGI compiler, but this R instance was compiled with GCC. The Rmpi package can be compiled and installed with %R CMD INSTALL Rmpi_0.5-5.tar.gz

Hello R-help! I am a systems administrator for the University of Southern California. I take care of it's general-purpose research cluster, and have recently been asked to provide access to a parallelized R platform. I do not have any previous experience using R, and have only ever had to do anything more then 'yum -y install R'. We have a myrinet MPI network, and use mpich1 as our

I am running R 2.14.1 on a Windows XP (32 bit) system, and am trying to install the package 'Rmpi' to allow me to parallel process on all cores of a quad-core PC (and if that works well, I want to add extra slaves from a dual-core laptop). Rmpi appears to install OK (see below), but I am encountering the following error when I try and load the package: > utils:::menuInstallLocal()
