Subject: Re: [OMPI users] connect() fails - inhomogeneous cluster

I should have written that...
 
mpirun -np n --hostfile host.cfg
 
mpi@Ries   slots=n_1 max_slots=n_1
mpi@Euler  slots=n_2 max_slots=n_2
 
It is arranged that the sum over the n_i is equal to n.

Hi,

> this is the first time I contact this list. I'm using OpenMPI 1.6.5 on an inhomogeneous cluster with 2 machines. Short: With few processes everything works fine but with some more my application crashes. (Yes, I can guarantee that in every scenario I start processes on both machines). I posted the problem already with all details on stackoverflow (http://stackoverflow.com/questions/24164825/mpi-connect-fails-inhomogeneous-cluster). Please have a look at it. What exactly is the problem and how can I fix it?

How do you start the program - just with `mpiexec` and a proper hostfile and number of slots?
