Hi,
I'm using a supercomputer to run clm5.0 and have set ./xmlchange NTASKS=64 and
#SBATCH --nodes=4
#SBATCH --ntasks-per-node=16 (max per node)
in a slurm sbatch file.
However, I found the running speed of 16 ntasks (i.e., nodes=1) is the same or even faster than 64 ntasks (i.e., nodes=4),
the mpirun I'm using is mpich-3.3.1, it was loaded locally and wasn't moduled by the supercomputer moduleing system.
Does anybody know how to use more cores tu run clm5.0? Thanks
