...------------------------------------------------------------- It seems that there is no lamd running on the host erin-laptop. This indicates that the LAM/MPI runtime environment is not operating. The LAM/MPI runtime environment is necessary for the "mpirun" command. Please run the "lamboot" command the start the LAM/MPI runtime environment. See the LAM/MPI documentation for how to invoke "lamboot" across multiple machines. ----------------------------------------------------------------------------- I have both lam and openmpi installed on my Ubuntu 9.04.

Dear R Gurus: Is there a problem with Rmpi on x86 with SUSE 10.1, please? I've tried everything and it still won't load. Has anyone else dealt with this please? Thanks, Edna Bell

I'm having trouble with R CMD INSTALL Rmpi_0.5-5.tar.gz --configure-args=~/lam lam is is installed locally. lamboot -d (or lamboot-d and also recon) works. make -k check from the lamtest suite passes all tests. Is this is problem with the -fPIC compiler as in the message? Should it be modified in the Makefile? Any help or comments are appreciated, thanks. * Installing to library '/u1/uaf/ogorman/R/x86_...

...as expected. When I try to make a cluster including another networked machine it hangs. I've followed the suggestions at http://finzi.psych.upenn.edu/R/Rhelp02a/archive/83086.html and http://www.stat.uiowa.edu/~luke/R/cluster/cluster.html but to no avail. Everything seems to start up fine using lamboot, but then hangs when making the cluster in R. Making a cluster with 2 slaves seems to work fine, but if I increase the number (to use the networked machines) it hangs again. I've tried networking to another Mac, and also to a machine running Red Hat Linux. Both machines can set up their own lo...

...ous difficulties were that, first, I had to manually load the serialize library (which now conflicts with the name of something in the base package) and, second, that whenever I say makeCluster or makeMPIcluster the thing just hangs up. I've tried various permutations of running or not running lamboot first. I am able to to lamboot and lamexec, and I also tried setting LAMRSH to use ssh on the master. My "network" is just my dual-CPU machine. Tony Rossini's notes (http://www.analytics.washington.edu/~rossini/courses/cph-statcomp/cph-4.pdf) refer to SNOW and rpvm as being "c...

...may load and then immediately terminate R as the lam helpfile is not found (which is not nice of the lam libs). You may need to export LAMHOME=/usr/lib64/lam . Even if the helpfile is found, it still terminates R if lamd is not running. (As I recall previous RPM installations had run lamboot at system boot.) - The final step is to start a lam configuration. I was only able to do this by setting -prefix, e.g. /usr/lib64/lam/bin/lamboot -prefix /usr/lib64/lam -- Brian D.

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?

...such file or directory Error in dyn.unload(x) : dynamic/shared library '/home/apps/R-2.2.0/lib/R/library/Rmpi/libs/Rmpi.so' was not loaded Error in makeMPIcluster(spec, ...) : the `Rmpi' package is needed for MPI clusters. The Rmpi.so exists and the permissions are fine. I also did a lamboot, and its running in the backround fine as well. Any suggestions? Thanks.

I just installed Rmpi on my 64-bit Ubuntu Hardy Heron OS and using the following without errors: "R CMD INSTALL Rmpi_0.5-5.tar.gz --configure-args=--with-mpi=/usr/lib64/openmpi" Immediately at library(Rmpi) I get the segfault displayed in my complete output below. My first thought is that perhaps I used the wrong library for openmpi, but with my 64 bit install it seemed like a logical

...ystem to a known seed, how do I do it? That is, I want each distributed process to recreate exactly the same random numbers that it did before; I assume SPRNG assures the streams are independent betweeen processes. Here's what I did, trying to stick within SNOW to avoid trouble (from memory): lamboot start up R library(snow) library(rsprng) library(rmpi) cl<-makeMPIcluster(11) clusterSetupSPRNG(cl, seed=123) clusterEvalQ(cl, source("mycode.R")) r<-parSapply(cl, seq(1000), function(i) doMyThing())) Any comments on that? For example, would sticking to Rmpi and using parSim make...

Dear R People: I'm having some trouble with mpiexec and Rmpi.
