Real-Time Ocean Forecast System (RTOFS)

The Global RTOFS system at NCEP based on HYCOM-CICE and NCODA

The global-workflow depends on the following prerequisities to be available on the system:

• modules - NCEPLIBS (various), hdf5, intel/ips v18, wgrib2, netcdf v4.7.4, gempak (see files under /versions for additional details)

RTOFS-GLO current supports the following machines:

• WCOSS2
• NOAA RDHPCS: Gaea C6, MSU-HPC, Ursa for forecast model only.

Building RTOFS:

1. Base check out

git clone git@github.com:NOAA-EMC/RTOFS_GLO.git
cd RTOFS_GLO/sorc

Note:

• If you have no intention to develop anything and want to merely use RTOFS, see below.
• Instead of clone using: git clone git@github.com:NOAA-EMC/RTOFS_GLO.git,
• Do: git clone https://github.com/NOAA-EMC/RTOFS_GLO.git.

2. Build components

1. Forecast model:

   • Use ./build_forecast.sh <RUN_ENVIR> <machine_name>
   • Notes:
     • Allowed RUN_ENVIR= nco, emc.
     • machine_name = wcoss2, ursa, orion, gaeac6.
     • For all development on WCOSS-2: ./build_forecast.sh emc wcoss2
       • Other than WCOSS-2: ./build_forecast.sh emc <machine_name>

2. Rest of the utilities, including NCODA (requires access to NCODA repository), on wcoss2 only:

   • Use build_ncoda_and_rtofs_utils.sh <machine_name>
   • Notes:
     • Allowed machine_name= wcoss2 (only).
     • Relies on sorc/build_rtofs.sh.

Remarks:

• If building NCODA only, use: sorc/build_rtofs_ncoda.sh
