I'm trying to get slurm and openmpi to work together on a debian, two
node cluster. Slurm and openmpi seem to work fine seperately, but when
I try to run a mpi program in a slurm allocation, all the processes get
run on the master node, and not distributed to the second node. What am
I doing w

Open MPI and SLURM should work together just fine right out-of-the-box. The
typical command progression is:
srun -n x -A
mpirun -n y .
If you are doing those commands and still see everything running on the head
node, then two things could be happening:
(a) you really aren't getting an allo
ah, disregard..

It seems from what you said that the DLPOLY program would fail with or
without SGE is being used. Since I am not familiar with DLPOLY, I am a
little clueless as to what else you can try. Perhaps you can try looking
deeper into DLPOLY by having a debuggable build and running a parallel
debugger
Beware: this is a lengthy, detailed message.

Thanks for your response. The program that I have been using for testing
purposes is a simple hello:
#include

main(int argc, char *argv)
{
char name[BUFSIZ];
int length;
int rank;
struct rlimit rlim;

I think the SLURM code in Open MPI is making an assumption that is
failing in your case: we assume that your nodes will have a specific
naming convention:
mycluster.example.com --> head node
mycluster01.example.com --> cluster node 1
mycluster02.example.com --> cluster node 2
...etc.

I had been using MPICH and its serv_p4 daemon to speed startup times.
I've decided to try OpenMPI (primarily for the fault-tolerance features)
and would like to know what the equivalent of the serv_p4 daemon is.
It appears as though the orted daemon may be what I am after but I don't

Thanks for the help I renamed the nodes, and now slurm and openmpi seem
to be playing nicely with each other.
