Hi Ralph,
Thank you for your quick response. I'd like to report one more regressive issue about Torque support of openmpi-1.7.4a1r29646, which might be related to "#3893: LAMA mapper has problems" I reported a few days ago. The script below does not work with openmpi-1.7.4a1r29646, although it worked with openmpi-1.7.3 as I told you before. #!/bin/sh #PBS -l nodes=node08:ppn=8 export OMP_NUM_THREADS=1 cd $PBS_O_WORKDIR cp $PBS_NODEFILE pbs_hosts NPROCS=`wc -l < pbs_hosts` mpirun -machinefile pbs_hosts -np ${NPROCS} -report-bindings -bind-to core Myprog If I drop "-machinefile pbs_hosts -np ${NPROCS} ", then it works fine. Since this happens without lama request, I guess it's not the problem in lama itself. Anyway, please look into this issue as well.
