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: ")

??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

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

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

Dear mac folks, I have started porting a large legacy toolset maintained in windows and heavily mpi laden so it can be used across platforms in R... so I am building a package out of it. On this note, I am noticing that almost all of the mpi dependent packages do not compile on the CRAN repositories.... with the basic issue that it appears it can not find mpi installed: configure: error:

Hello, I'm using R on a 10 blade dual quad core Rocks Cluster, and trying to use Rpmi and snow. I basically wondered if at the moment I ought to install Rmpi against another form of mpi (not openmpi) and wondered whether anyone could pass on any experience. I'm mainly worried about (a) the R server taking up 100% cpu time (I think this is a known issue with Rmpi and openmpi) and (b)

Hello, I plan to use R with my cluster with OpenMPI. I need the packaged 'snow' and 'Rmpi' for that, however, I get an error while downloading and installing them: When I do a: install.packages("Rmpi", dependencies=T) I get this error: checking for mpi.h... no Try to find libmpi.so or libmpich.a checking for main in -lmpi... no libmpi not found.

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: >

R developers: I have some parallel C code, written with the MPI library, that I would like to call from R, but I get the error message below. cocite.mat.true.parallel.so compiles without complaint and I have MPI in my path, but R isn't recognizing one of the MPI symbols. I have a feeling that this is going to be tricky, but I need to get this to work. Helpful suggestions? I'd be

Hi all: Can dtrace trouble-shoot the MPI porgrams (HPC programs)? Does there exist an extension on dtrace to debug MPI program? If exist, then where can I find the how-to documentations? Thanks in advance? Regards TJ -------------- next part -------------- An HTML attachment was scrubbed... URL:

On FC10 with openmpi and mpich2 installed, the command "R CMD INSTALL Rmpi_0.5-7.tar.gz --configure-args=--with-mpi=/usr/lib64/openmpi" (or /usr/lib64/mpich2) fails with the error ''cannot find mpi.h". Doing a (s)locate indicates no header file labeled as such. Would appreciate any trailheads. TIA, V. -- Vince Fulco, CFA, CAIA 612.424.5477 (universal) vfulco1 at

Hi Guys, I have a xen set up with two domu VM''s. One of these VM has recently crashed and was running lot of web services.

I've done a little digging, but I haven't been able to find an MPI or snow (or any other distributed processing) implementation of fanny (from cluster) or cmeans. Is anyone aware of some implementations or addons which I've missed?

Dear R users, did anybody hack MPI bindings for R? (hoping somebody did that for me before :) Otherwise I might do that soonish. Anybody out there who has some special wishes for that? If yes, please email me directly.. as I'll spend a few days thinking about how to do that best and then do it. (Note: I'm not producing a parallel, thread-safe version of R) Armin

Hi, I would like to compile a shared C++ library but using MPI. Is there away to compile shared libraries using the functionality of mpiexec supplied with MPICH-2. Thanks for any help, Jarrod

Hello, I don't know if the question pertains to Rmpi, snow or snowfall. I run my job by: mpirun -np N -hostfile $PBS_NODEFILE RMPISNOW -f my-script.r --slave In the snowfall sfInit call I have to specify one less CPU respect to the mpirun call sfInit(parallel=TRUE, cpus=N-1, type="MPI") otherwise I receive an error similar to: "cluster size N-1 already

Hello all, I am working over porting Xen''s migration functionality over an MPI providing RDMA schematics. I wish to know where I could find detailed documentation of Xen migration alone, and how to go about developing it. Will the xen-developers list help? Thanks & Regards, Siddharth Wagh
