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 & 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 & 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 & 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:

tail -n 1 log.ocean.0000.out
 Logging complete.  Closing file at ...

For the global test case, please download here: MPAS-O_V6.0_RRS30to10.tar. Please see http://mpas-dev.github.io for User's Guide, github release page, description of each test case, and more.
