Sorry for  the spam of my previous message. It seems the error is due to the deinoMPI service did not start automatically.
> mpi.spawn.Rslaves()
        4 slaves are spawned successfully. 0 failed.

Subject: help on Rmpi and deinoMPI error  in mpi.comm.spawn

Dear List,
I got a problem on installing Rmpi and deinoMPI. please help. tjhanks!

I installed deinoMPI ver 1.1.0 and Rmpi 0.5-7.zip for deinoMPI from http://www.stats.uwo.ca/faculty/yu/Rmpi/.
My operating system is 32-bit windows xp sp3 English verison, R version is 2.9.1.
I got error as below
> library(Rmpi)
> mpi.spawn.Rslaves()
Error in mpi.comm.spawn(slave = system.file("Rslaves.bat", package = "Rmpi"),  : 
MPI_Comm_spawn(193)...........: MPI_Comm_spawn(cmd="C:/PROGRA~1/R/R-29~1.1/library/Rmpi/Rslaves.bat", argv=0x05EED7B8, maxprocs=4, MPI_INFO_NULL, root=0, MPI_COMM_SELF, intercomm=0x059D7030, errors=0x05834A18) failed
MPIDI_Comm_spawn_multiple(282): PMI_Spawn_multiple returned -1, Object reference not set to an instance of an object.

If I uninstall deinoMPI ver 1.1.0 and install deinoMPI 2.0, I got error even earlier on >library(Rmpi):
SystemError: The program can't start because deino_mpich2mpi.dll is missing from your computer.

I also tried combination of R 2.8.1/R 2.9.0/ deinoMPI version of Rmpi 0.5-6.zip. no luck.

Thanks for any reply.
