I'm really naive and know almost nothing about MPI. I'm trying to do some analyses in R that require Rmpi package. But I'm stuck with this problem: 

Version of R 3.2.5 (x64) on Windows 10

I installed MPICH2

Added proper addresses on PATH environment variables

Successfully set smpd and mpiexec registration 

Installed Rmpi using Rgui

If I call Rmpi using normal Rterm it is loaded. But when I try

mpi.spawn.Rslaves(), it returns :

Error in mpi.spawn.Rslaves() : Spawning is not implemented. Please use mpiexec with Rprofile.*

so I run on prompt : 

mpiexec  -n 2 "C:\Program Files\R\R-3.2.5\bin\x64\Rterm.exe" --no-save –q

So far so good.

I can load any package without problems but when it comes to call Rmpi library I get this error message:

Aborting: mpi appplication on DESKTOP-0UI5TAT is unable to connect to the smpd manager on (null):57362 error 1722

job aborted: [ranks] message [0] fatal error Fatal error in MPI_Init: Other MPI error, error stack: MPI_Init(argc_p=0x0018FA44, argv_p=0x0018FA48) failed The RPC server is unavailable. (errno 1722)*

Even using the more recent MS-MPI software, when I call Rmpi it simply starts a new line without any prompt > and so it remains

I deep searched on the whole internet and tried several options but it's still not working

you have to create a shortcut that Rstudio is lunched by mpiexec ,otherwise the Rstudio doesn't know Mpi follow instruction here http://www.stats.uwo.ca/faculty/yu/Rmpi/
