Hello there,I am trying to run CESm1.2.2.1 with case ne120_t12.I have lnd model uses 360 MPI tasks, ice 720, and ocn 360, then set OMP_NUM_THREADS=2.When I run it, I got error:  Warning: Departure points out of bounds in remap my_task, i, j =         541           5          19 dpx, dpy =  -26.2273426325629        5891.85314100767 HTN(i,j), HTN(i+1,j) =   3890.42157100753        3894.98816049952 HTE(i,j), HTE(i,j+1) =   3788.50188375742        3786.49589919537 istep1, my_task, iblk =           1         541           3 Global block:       10961 Global i and j:         404        2298(shr_sys_abort) ERROR: remap transport: bad departure points(shr_sys_abort) WARNING: calling shr_mpi_abort() and stoppingapplication called MPI_Abort(MPI_COMM_WORLD, 1001) - process 901  Warning: Departure points out of bounds in remap my_task, i, j =         627          26          20 dpx, dpy =   5653.99189425681        23.1312094799313 HTN(i,j), HTN(i+1,j) =   3553.09642109926        3558.88556378382 HTE(i,j), HTE(i,j+1) =   3347.88520022242        3346.32650895058 istep1, my_task, iblk =           1         627           4 Global block:       11102 Global i and j:         350        2329(shr_sys_abort) ERROR: remap transport: bad departure points(shr_sys_abort) WARNING: calling shr_mpi_abort() and stoppingapplication called MPI_Abort(MPI_COMM_WORLD, 1001) - process 987 It works fine with OMP_NUM_THREADS=1, and lnd 720, ice 1440, and ocn 720 cores. Could you please help me fix this problem? Thanks, Wei

Actually, adjust the ice dynamics timestep sndt_dyn did not make much sens, as the code runs fine with OMP_NUM_THREADS=1.It is more related to some env. variable setup, not CFL valiation.
