I have been working through the porting guide. First, I have been successful at running the test MPI program, the X configuration, and the X configuration with machine-specific options. From there, I have run into two issues. The User's Guide tells me: "You will want to start with an X (i.e. commonly referred to as dead) compset running at a low resolution. So you could, for instance, start with an X compset at resolution f45_g37. This will allow you to determine whether all prerequisite software is in place and working for a simple parallel CESM configuration that requires minimal input data. Once that is working move to an A compset with resolution f45_g37. Once that’s working, run a B compset at resolution f45_g37. Finally when all the previous steps have run correctly, run your target compset and resolution." I started by trying an A configuration with this script.> ./create_newcase -case /data/no_backup/heavens/CESM/casedir/testA -res T31 -compset A -mach aimproc1I then receive: "ERROR: 2000_DATM%NYF_DLND%NULL_DICE%SSMI_DOCN%DOM_DROF%NYF_SGLC_SWAV is not supported for a%4x5_l%4x5_oi%gx3v7_r%r05_m%gx3v7_g%null_w%null" I then tried AWAV.> /create_newcase -case /data/no_backup/heavens/CESM/casedir/testA -res f45_g37 -compset AWAV -mach aimproc1 "grid longname is f45_g37 Component set: longname (shortname) (alias) 2000_DATM%WW3_DLND%NULL_DICE%COPY_DOCN%COPY_DROF%NULL_SGLC_WW3 (A2000_W) (AWAV) Component set Description: DATM: DLND: DROF: DICE: DOCN: SGLC: WW3: present day: dlnd modes are DLND_SNO_MODE=NULL, DLND_MODE=NULL: NULL drof mode: dice mode is copy: docn copy mode: Grid: a%4x5_l%4x5_oi%gx3v7_r%r05_m%gx3v7_g%null_w%null (4x5_gx3v7) ATM_GRID = 4x5 NX_ATM=72 NY_ATM=46 LND_GRID = 4x5 NX_LND=72 NX_LND=46 ICE_GRID = gx3v7 NX_ICE=100 NX_ICE=116 OCN_GRID = gx3v7 NX_OCN=100 NX_OCN=116 ROF_GRID = r05 NX_ROF=720 NX_ROF=360 GLC_GRID = 4x5 NX_GLC=72 NX_GLC=46 WAV_GRID = null NX_WAV=0 NX_WAV=0 Grid Description: null is no grid: 4x5 is FV 4-deg grid: gx3v7 is Greenland pole v7 3-deg grid: r05 is 1/2 degree river routing grid: Non-Default Options: ATM_NCPL: 48 BUDGETS: FALSE CCSM_BGC: none CCSM_CCOST: -3 CCSM_CO2_PPMV: 367.0 COMP_ATM: datm COMP_GLC: sglc COMP_ICE: dice COMP_LND: dlnd COMP_OCN: docn COMP_ROF: drof COMP_WAV: ww3 CPL_ALBAV: false CPL_EPBAL: off DATM_MODE: WW3 DATM_PRESAERO: none DICE_MODE: copyall DLND_MODE: NULL DLND_SNO_MODE: NULL DOCN_MODE: copyall DROF_MODE: NULL OCN_NCPL: $ATM_NCPL OCN_TIGHT_COUPLING: FALSE ROF_NCPL: $ATM_NCPL SCIENCE_SUPPORT: NO SSTICE_DATA_FILENAME: $DIN_LOC_ROOT/atm/cam/sst/sst_HadOIBl_bc_0.9x1.25_clim_c040926.nc SSTICE_GRID_FILENAME: $DIN_LOC_ROOT/atm/cam/ocnfrac/domain.camocn.0.9x1.25_gx1v6_090403.nc The PE layout for this case match these options:GRID = a%4x5Creating /data/no_backup/heavens/CESM/casedir/testA cp: cannot stat `/data/no_backup/heavens/CESM/cesm1_2_2/models/wav/ww3/bld/*build*.csh': No such file or directoryERROR: cp -p /data/no_backup/heavens/CESM/cesm1_2_2/models/wav/ww3/bld/*build*.csh /data/no_backup/heavens/CESM/casedir/testA/Buildconf/. failed: 256" There is no ww3 directory in the release! Then I tried the first test case in Step 3.> ./create_test -testname ERS_D.f19_g16.X.aimproc1 -testid t01 "** Directory baselineroot does NOT exist (UNSET)" Has anyone encountered these problems? Found any workarounds? I am now going to try a bog standard B case (B_1850_CN at 0.9x1.25_gx1v6) in the hope that this functions.
