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 (rank 3, comm 1) of size 5 is running on: MyMaster slave4 (rank 4, comm 1) of size 5 is running on: MyMaster > mpichhosts() master slave1 slave2 slave3 slave4 "localhost" "localhost" "localhost" "localhost" "localhost" > mpi.universe.size() [1] 4 > mpi.close.Rslaves() [1] 1 library(doSNOW) But every time I try to set up a cluster via cluster <- makeCluster(4, type = "MPI") My computer hangs up and I have to close the R session. Any advice how I get this running?
