new mesh capabilities in component caps

new mesh capabilities in component caps This PR puts new mesh capability into each component nuopc cap and into the data model caps

• new mesh files are now being generated in the directory: $DIN_LOC_ROOT/share/meshes The process for generating these files is to determine th SCRIP grid description file that was used to generate the corresponding domain file and use the command mpirun -np 2 ESMF_Scrip2Unstruct 0 ESMF

• each prognostic component now:

  • after its own initialization, the component reads in an ESMF mesh file
  • a new mesh is created using the read in mesh and a distgrid that is created from the global index space produced by the component initializaiton
    • for clm, the distgrid that is used to create the mesh has ocean points added to the end of each land gindex so that a global distgrid without holes can be sent back to the mediator
    • for cice, the distgrid that is used to create the mesh has any land block eliminated points added back into the the pe0 so that a global distgrid without holes can be sent back to the mediator
  • a check is done to determine if the mesh lats and lons are the same as the lats and lons generated internally by the component to some set tolerance level

• each data component now:

  • reads in the ESMF mesh and obtains its distgrid from the read in mesh
  • uses that distgrid to generate a gsmap for the component
  • passes that gsmap to the shr_strdata_init call - thereby eliminating the need for an mct rearranger in the data model nuopc cap.
  • a check is done to determine if the mesh lats and lons are the same as the lats and lons generated internally by the component to some set tolerance level
  • currently the component ggrid uses the domain lats and lons for the mapping of the streams to the component - but the mesh lats and lons to pass back to the mediator - THIS NEEDS TO BE ELIMINATED in the next update since it will change answers

• the data model shr_strdata_mod and shr_stream_mod have been modified as follows:

  • shr_strdata_init has been broken up into 3 subroutines:
    • shr_strdata_init_model_domain
    • shr_strdata_init_streams
    • shr_strdata_init_mapping this has enabled the capability to call these routines independently and not require the ordering imposed by the initial implementation
  • shr_dmodel_mod now can have a gsmap passed in directly in order to determine the component ggrid

• added new tests for DWAV and DLND

• notes on comparison to old baseline (/glade/scratch/mvertens/BASELINES/nov08)

  • The following tests showed a failure - but the only difference was fill pattern diffs ERS_Vnuopc_Ld5.T62_g16.GMOM.cheyenne_intel.mom-nuopc_cap ERS_Vnuopc_Ln5.f45_f45_mg37.I2000Clm50SpNuopc.cheyenne_intel.clm-nuopc_cap SMS_Vnuopc_Ld5.T62_g16.GMOM.cheyenne_intel.mom-nuopc_cap SMS_Vnuopc_Ld5.f19_g16.BMOM.cheyenne_intel.allactive-nuopc_cap_io SMS_Vnuopc_Ln5.f45_f45_mg37.I2000Clm50SpNuopc.cheyenne_intel.clm-nuopc_cap

  • The following tests differed in roundoff levels at the first timesteps ERS_Vnuopc_Ln5.f19_g17.F2000Nuopc.cheyenne_intel.cam-nuopc_cap SMS_Vnuopc_Ln5.f19_g17.F2000Nuopc.cheyenne_intel.cam-nuopc_cap ERS_Vnuopc_Ln9_N3.T31_g37_rx1.A.cheyenne_intel SMS_Vnuopc_Ld1_N3.T31_g37_rx1.A.cheyenne_intel
