Dear Scientists,I am trying to simulate aerosol distribution on CESM 1.2.2.Using the following model configuration：-res f19_g16 -compset FC5-phys cam5 -chem trop_strat_mam3 -nlev 56 -offline_dynEnvironmental configuration:intel-compilers/14.0.2  MPI/Intel/MPICH/2.1.5  pnetcdf/1.6.1/01-icc13It runs very slowly, with 96 cores (4 nodes) 5 months/day, which is one-thirtieth of the normal speed. I also tried 10 cores (3months/day), 120 cores (5months/day) ) and 240 cores (5months/day), obviously this is not a normal running speed. Does anyone know the reason?
