Hi, I try use Rmpi package to my compute. In my work I'm using eclipse version 3.6.2 and statEt version 0.10.0 (launch Rterm or RJ). Actually I observed strange behavior, when I try loading Rmpi directly I don't have any problem i.e.: library("Rmpi") mpi.spawn.Rslaves() 8 slaves are spawned successfully. 0 failed. master (rank 0, comm 1) of size 9 is running on: marcin-HP

R-users, My question is related to earlier posts about benefits of quadcore over dualcore computers; I am trying to setup a cluster of windows xp computers so that eventually I could make use of 10-20 cpu:s, but for learning how to do this, I am playing around with two laptops. I thought that the package snow would come handy in this situation, but to use snow, I would probably need to install

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

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

Hi I have managed to install MPICH2 and Rmpi on my Windows 7 machine. I can also run the following code > library(Rmpi) > mpi.spawn.Rslaves() 4 slaves are spawned successfully. 0 failed. master (rank 0, comm 1) of size 5 is running on: MyMaster slave1 (rank 1, comm 1) of size 5 is running on: MyMaster slave2 (rank 2, comm 1) of size 5 is running on: MyMaster slave3

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

Dear R Users, I am attempting to use the snow package for clustering. Is there a way to identfy, in the environment of each node, a rank for that node and also, the total size of the cluster ? By way of analogy, I am looking for the functions in snow equivalent to mpi.comm.rank() and mpi.comm.size() from RMPI, in case that makes things clearer. Thanks in advance, Tolga Generally, this

Hello R users and developers, I would like to install Rmpi so that I may take advantage of all of the CPUs in my computer, but I cannot get it to install and I am not very good with linux so it is adding to the headache. I have looked through the help archive, but I have not been successful at getting Rmpi to work. I am not sure if I am even installing openMPI correctly in linux. I would really

??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

Well, i'm just ordinary samba user, but if i can make a request for next samba release: 1. Samba should support ldap referral and has appropriate waiting slave database synchronized. ie, in smb.con we can give: passdb backend = ldapsam:"ldap://slave1 ldap://slave2 ldap://master" sync timout = 10 or user shoud manually tell where is the master and slave: ldap master server =

Trying to understand how puppet reports errors Example of why I am asking the question (on a test setup environment) Created a base-1 node Created 2 slave nodes that inherit from base-1 Let''s call those slave1 and slave2 No errors. It all works. Created a base-2 node created a third slave that inherits from base-2. Let''s call that slave3 Get an error Could not retrieve

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 DeinoMPI GUI. Thanks in advance, Tolga

Hello everyone I am running into some strange issues when configuring networking interfaces on my physical server running Centos 7.5. Let me give you an overview of what's going on: We have a physical server, running CentOS 7.5. This server has one 4 port NIC and one 2 port NIC and a Dell IDRAC port. The first port of the 4 port NIC, em1, is used for Management traffic. The first port of

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

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: ")
