Dear R Users, I have set-up: - R 2.7.2 - rmpi using deinoMPI, and - snpw on two Windows XP machines. I would like to use the makeCluster(...,"MPI") command to create a cluster. Assume the machines are A and B. I would like the master to be on A and the nodes to be on B. How do I achieve this outcome ? I can see both machines using the DeinoMP...

...handy in this situation, but to use snow, I would probably need to install package Rmpi first. I might also like to use Rmpi directly. In order to use Rmpi in windows, I need to install MPI middle-ware, for which I have found two options: MPICH2: http://www.mcs.anl.gov/research/projects/mpich2/ DeinoMPI: http://mpi.deino.net/ First I tried MPICH2 1.06 + R-2.6.0 + Rmpi 0.5-5. (I downloaded windows binaries of Rmpi from Rmpi website :http://www.stats.uwo.ca/faculty/yu/Rmpi/) With MPICH2 I managed to connect my computers so that I was able to remotely launch Rgui on both machines but R hanged when...

...z This substantially revises the way in which worker processes are started to allow snow to be used on Windows and Mac/Windows/Linux combinations. I have successfully used the SOCK version on a standalone Windows machine and combinations of Windows and Linux; the MPI version also works for me with DeinoMPI and the Rmpi verision for DeinoMPI. I would welcome it if some current snow users could try this verison in their settings to help iron out any major issues I missed before release to CRAN.

...ot; and "Rmpi". snow seems more user friendly, but it doesn't run on windows. I see from searching the mailing list that I'm not the first one to try it on Windows. There was a message that kind of shed some hope on the subject, but nothing else. Rmpi works well on windows (with DeinoMPI) but it's kind of low level, so before I embark in writing code similar to snow to have some high level constructs I though I'd ask here about other peoples experiences... Is anyone around here doing parallel R on Windows? If so could you share your experience? Cheers, // Giuseppe *****...

Dear R Users, I am attempting to use snow with rmpi. My configuration is: - R Version 2.7.2, rmpi - RMPI 0.5-6 - DeinoMPI 1.1.0 - Windows Xp SP2 I can sucessfully create a cluster and execute simple commands but for some reason, I cannot change the working directory in my nodes. > noclusters<-2 > cl <- makeCluster(noclusters, type = "MPI") 2 slaves are spawned successfully. 0 failed. &...
