Re: mpirun octave hangs

[Michael Creel]

Ah, perhaps I see now. The mpi package for Octave is not used interactively.
You need to use something like:

address@hidden:~$ mpirun -np 3 octave -q --eval "MPI_Init;
COMM=MPI_Comm_Load('NEWORLD'); node=MPI_Comm_rank(COMM); printf('hello from
%d\n', node); MPI_Finalize"

the output of which is

hello from 0
hello from 1
hello from 2
ans = 0
ans = 0
ans = 0
address@hidden:~$ 

There was a package called MPITB which worked interactively, which was quite
neat. That is out of date for modern Octaves, though.
