Dear Franklin users, This is a reminder that during phase 3a (Sept 10 to Sept 17 7:30am), there are over 10k dual cores on Franklin available. Since majority users are submitting jobs on the quad cores, it is a good opportunity to submit jobs on the dual core nodes to get much faster throughput. The quad core compiled executables will not run on the dual core nodes. To compile for the dual core nodes, issue "module unload xtpe-quadcore" first, then recompile: franklin% module unload xtpe-quadcore franklin% ftn ... or franklin% cc ... or franklin% CC ... To run on the dual core nodes, make sure you have "#PBS -l feature=dual" and "#PBS -l mppnppn=2" lines in the job script. Below is a sample job script to run on the dual core nodes: #PBS -q debug #PBS -l mppwidth=8 #PBS -l feature=dual #PBS -l mppnppn=2 #PBS -l walltime=00:10:00 #PBS -j eo cd $PBS_O_WORKDIR aprun -n 8 -N 2 ./a.out Best Regards, Helen He NERSC User Services _______________________________________________ franklin-users mailing list franklin-users_at_nersc_dot_gov
