Hello there, I am trying to do a dummy point simulation of the CLM following instructions in the CLM4.5 in CESM1.2.2 manual. But it is taking a very very long time for me to generate one of the mapping files. The specific command is reproduced below: ================mpiexec -pernode /nfs/17/osu6925/local/ncl-6.3.0/bin/ESMF_RegridWeightGen --ignore_unmapped -s /nfs/gpfs/PAS0661/inputdata_cesm1_2_2/lnd/clm2/mappingdata/grids/UGRID_1km-merge-10min_HYDRO1K-merge-nomask_c130402.nc -d ../mkmapgrids/SCRIPgrid_1x1_Ohio_nomask_c150814.nc -m conserve -w map_1km-merge-10min_HYDRO1K-merge-nomask_to_1x1_Ohio_nomask_aave_da_c150815.nc --dst_regional --src_type UGRID --src_meshname landmesh --dst_type SCRIP --netcdf4 -verbose =================Output: Starting weight generation with these inputs: Source File: /nfs/gpfs/PAS0661/inputdata_cesm1_2_2/lnd/clm2/mappingdata/grids/UGRID_1km-merge-10min_HYDRO1K-merge-nomask_c130402.nc Destination File: ../mkmapgrids/SCRIPgrid_1x1_Ohio_nomask_c150814.nc Weight File: map_1km-merge-10min_HYDRO1K-merge-nomask_to_1x1_Ohio_nomask_aave_da_c150815.nc Source File is in UGRID format, dummy variable: landmesh Source Grid is a global grid Source Grid is an unstructured grid Destination File is in SCRIP format Destination Grid is a regional grid Destination Grid is a logically rectangular grid Regrid Method: conserve Pole option: NONE Ignore unmapped destination points Output weight file in NetCDF4 file format Norm Type: dstarea=================The output just hangs there until the job is killed. I have been requesting resources for 1 node X 12 PEs, walltime = 3 hours, but the command does not finish. Is this reasonable?I am using the ESMF_RegridGenWeight function from NCL, which may be an issue. But testing with the other data, netcdf4 output seems to work fine: ESMFBIN_PATH=~/local/ncl-6.3.0/bin/$ESMFBIN_PATH/ESMF_RegridWeightGen --ignore_unmapped -s $CSMDATA/lnd/clm2/mappingdata/grids/SCRIPgrid_0.9x1.25_GRDC_c130307.nc -d ~/cesm1_2_2/models/lnd/clm/tools/shared/mkmapgrids/SCRIPgrid_1x1_Ohio_nomask_c150815.nc -m conserve -w map_0.9x1.25_GRDC_to_1x1pt_US-UMB_nomask_aave_da_c130905.nc --dst_regional --src_type SCRIP --dst_type SCRIP --netcdf4 Any suggestions will be greatly appreciated.
