LIGGGHTS under Sun Grid Engine

Submitted by tkulju on Mon, 09/26/2011 - 07:28

Hi!
Has anybody got LIGGGHTS working under Sun Grid Engine with $round_robin -scheme? I've only managed to get it work with $fill_up and even then every calculating node for the simulation has been on the same computer. I'm using OpenMPI-1.5.3 and it has been compiled --with-sge (haven't seen any difference, if this flag has been used or not...). Without SGE it works perfectly fine. Some simple hostname calling scripts under SGE with mpirun works also fine.

By adding

export OMPI_MCA_orte_rsh_agent=rsh

in to the SGE-script and starting with (for 3 cores)

/nfsshare/openmpi-1.5.3/bin/mpirun --prefix /nfsshare/openmpi-1.5.3 -np 3 /nfsshare/liggghtsdev/src/lmp_fedora < in.script

solved the problem. If anybody has the similar issues, I can give more detailed information.
