openfoam spawning (may) extra processes
Dear all,
I am trying to run a code using 32 cores (2x16 cores nodes). After roughly 50 steps the PBS system kills my job: =>> PBS: job killed: ncpus 16.92 exceeded limit 16 (sum) mpiexec: killing job... I have tried to request 32 cores but use for example 26 cores and it doesn't fix the problem. My run script is: #!/bin/sh #PBS -l walltime=24:30:00 #PBS -l select=2:ncpus=16:mem=20000mb module load openfoam/2.1.0 module load intel-suite/10.1 cd /work/lm4112 #change to appropriate directory cp -r 60mm $TMPDIR #copy case directory to temp folder cd $TMPDIR/60mm #change directory to temp folder decomposePar #split domain into 32 subdomains #run case and re-direct output (log file) to /work directory for run-time checking mpirun -np 32 simpleFoam -parallel >/work/lm4112/60mm/simulation.log reconstructPar #put domain back together again foamToVTK -latestTime #conversion to VTK format cp -r 1000 VTK /work/lm4112/60mm #copy required files back to /work/case_directory #End someone have dealt with the same kind of problem? Thank you best regards Luca |
