[RegCNET] Performance of RegCM-4.4.5.7 on HPC systems

[Syed Ahsan Ali]

I have tested RegCM-4.4.5.7 simulation for South Asia region at
different number of cores and found that model performance is optimum
only till 88 processors with total memory 88GB, there is no
improvement afterwards. The model was compiled using gfortran and
OpenMpi is used for parallelism. Model resolution is 25km while time
step is 60s. Any further suggestions from experts to tweak the
simulation speed?
