Steve,
details might differ as I am running a different version of namd, and
hardware is obviously different.
here is a slurm script we use on our cluster:
-----------------------------------------------
#!/bin/csh
#SBATCH --mail-type=ALL
#SBATCH --partition=namd
#SBATCH --nodes=4
#SBATCH --ntasks=96
echo 'nodes: ' $SLURM_NNODES 'tasks/node: ' $SLURM_TASKS_PER_NODE 'total
tasks: ' $SLURM_NTASKS
set WORKDIR=/home/sharp/work/c166/
cd $WORKDIR
module load namd
make_namd_nodelist
charmrun ++nodelist nodelist.$SLURM_JOBID ++p $SLURM_NTASKS `which
namd2` +setcpuaffinity c166_s2000.conf > sharp_3Dec2018_.log
---------------------------------------------------------
namd is launched via charmrun with the
++nodelist hostnamefile
option.
this hostnamefile contains lines like:
host node023 ++cpus 2
host node024 ++cpus 2
for however many nodes you requested. It is generated at the time slurm
starts your job, because only at that time does slurm know the names of
the nodes it is allocating to this job. you get this node list by
executing the slurm command
scontrol show hostnames
in your job script and capturing/reformatting the output into the
nodenamelist file. here we have a script make_namd_nodelist that does
this, you can see it is executed right before the namd command
best
