Hi there,I want to ask how to load balance my simulation, since i only get 0.68 simulation years one wall clock day. I'm using CESM version 1.2.2, my compset choice is E1850C5CN with CN model been turned off (which means I set "CLM_CONFIG_OPTS"="-phys clm4_0"). And I set DEBUG=TRUE (False will lead to error).I use 6 nodes, 16 cores per node, so all together i have 96 cores, fully sequential PE layout setting (all components 96,1,0). STOP_OPTION=ndays, STOP_N=20, startup type, ColdSTART=on.Why the speed seems so slow ? I look into the time log, it seems the cam component run too slow. Below is my time log.
