Description

Derecho has TPN=128 but in most jobs we are vastly under-using these nodes. For example, the cpld_control_p8 test needs 200 tasks but the job card requests

#PBS -l select=3:ncpus=96:mpiprocs=96:ompthreads=1"

On Gaea, the same test uses

#SBATCH --nodes=2
#SBATCH --ntasks-per-node=128

srun --label -n 256 ./fv3.exe
