Hello!

I'm trying to run a very simple test with Rmpi via the mpirun function
outside of R.  Here is the script file:


Es-MacBook-Pro:~ emhodgess$ cat bb.in

library(Rmpi)

x <- 5

mpi.remote.exec(rnorm(x))

mpi.finalize()



And here is the output:

Es-MacBook-Pro:~ emhodgess$ mpirun -np 4 Rscript bb.in

Error in mpi.remote.exec(rnorm(x)) : It seems no slaves running.

Execution halted

Error in mpi.remote.exec(rnorm(x)) : It seems no slaves running.

Execution halted

Error in mpi.remote.exec(rnorm(x)) : It seems no slaves running.

Execution halted

-------------------------------------------------------

Primary job  terminated normally, but 1 process returned

a non-zero exit code.. Per user-direction, the job has been aborted.

-------------------------------------------------------

--------------------------------------------------------------------------

mpirun detected that one or more processes exited with non-zero status,
thus causing

the job to be terminated. The first process to do so was:


  Process name: [[39079,1],2]

  Exit code:    1

--------------------------------------------------------------------------

I had always thought that the numbers of workers was obtained from the np
value and passed through to R.  Apparently not.

Here is the session info:

I also did the same thing on my Ubuntu laptop; same results.

Any suggestions much appreciated.

Sincerely,
Erin
