Hello,

Recently the cluster I am using for computing has been updated to the VMware
with the Lustre file system.  Cluster uses: Oscar 6.0.3,  Sun Grid Engine
6.2u3, Nagios, Ganglia, InfiniBand 10 Gb/s. Nodes access the file system
using Ethernet via the Lustre InfiniBand/Ethernet router.

I used to run one type of jobs as:
---
#$ -N name
#$ -o namesys.out
#$ -e namesys.err
#$ -pe mpi 2
#$ -cwd
#$ -v LD_LIBRARY_PATH
mpirun -machinefile $TMPDIR/machines -np $NSLOTS /path/.../code.x << EOF
name.in
name.out
EOF
---

This is for an open source package (written in Fortran plus some C
utilities) and a such way of running was recommended by authors. It was
working on the previous version of the cluster, but it does not run on a new
lustre filesystem. It starts, but then stays in the queue forever.

Is it possible to run this type of jobs on lustre ?

Thank you.
Best wishes,
Goranka
