Semi-implicit barotropic mode solver using ForTrilinos in MPAS-O and its test data

To run the ForTrilinos-enabled MPAS-O, Download all files Install Trilinos Unzip: tar -xzvf Trilinos.tar.gz cd Trilinos ; mkdir build ; cd build ; cp ../do-configure_gnu ./ Check install directories and options in 'do-configure_gnu' Run 'do-configure_gnu' Trilinos information &amp; installation refer to https://trilinos.github.io/ Install ForTrilinos (inside Trilinos) cd Trilinos/ForTrilinos ; mkdir build ; cd build ; cp ../do-configure_gnu ./ Check Trilinos and ForTrilinos install directories and options in 'do-configure_gnu' Run 'do-configure_gnu' ForTrilinos information &amp; installation refer to https://fortrilinos.readthedocs.io/en/latest/ Install ForTrilinos-enabled MPAS-O Unzip: tar xzvf MPAS-Model_fortrilinos.tar.gz cd MPAS-Model_fortrilinos Check ForTrilinos directories at line 478 (FORTRILINOS_ROOT) in 'Makefile' Install PIO (refer to https://ncar.github.io/ParallelIO/) MAPS-O information &amp; installation refer to https://mpas-dev.github.io/ocean/ocean.html For GNU compiler: make gnu-nersc USE_PIO2=true FORTRILINOS=true Run test cases Example cd MPAS-O_Initial_data/baroclinicEddies/strong_scaling Link a MPAS-O compiled executable to a test case directory: ln -fs MPAS-Model_fortrilinos/ocean_model MPAS-O_Initial_data/baroclinicEddies/strong_scaling/ Link a XML deck (solver configurations) for Trilinos to a test case directory ln -fs xml_decks/no_precond/stratimikos.xml_SCG MPAS-O_Initial_data/baroclinicEddies/strong_scaling/stratimikos.xml Run mpirun -n $N ocean_model If the simulation was successful, you will see: <pre><code>tail -n 1 log.ocean.0000.out Logging complete.
