Hello,

 

Having a bit of trouble running Open MPI 1.2 under Torque 2.1.8.

 

My Script contains the following:

-----------------------------------------------

HPCC_HOME=/home/test/hpcc-1.0.0

ncpus=`wc -l $PBS_NODEFILE`

mpirun -np $ncpus $HPCC_HOME/hpcc

-----------------------------------------------

 

 

When I try to run on 4 nodes, 4 cpus each I receive the following in my err file:

 

[node003:04409] [0,0,4] ORTE_ERROR_LOG: Not found in file odls_default_module.c at line 1188

Has anyone seen this before? It seems odd that openmpi would be trying to execute what is effectively the host file. I stuck a sleep in to make sure the file was being distributed, and sure enough, it was there. I am able to run mvapich through torque without issue and openmpi from the command line.
