Running an idealised test case configuration with NEMO
We will now test NEMO by running a double gyre test case.
NEMOGCM/CONFIG and run
./makenemo -n GYRE_XIOS -m XC_ARCHER_INTEL -j 8 (took 121 seconds).
If you have loaded netCDF, HDF5 and installed XIOS correctly this should work. Go into
NEMOGCM/CONFIG/GYRE_XIOS/EXP00. Make a link to XIOS by:
ln -sf /path/to/xios/bin/xios_server.exe xios_server.exe
This particular branch needs the following namelist tweak (
Make a runscript named “run_gyre.pbs” like this:
NEMO will now run on 144 cores (6 nodes) and pass all output to XIOS on 3 cores (1 node) which will glue data from all processors into one file. You’re output should be in: GYRE_5d_0001010100011230_grid*.nc
(Hopefully!) congratulations, you’ve just run NEMO!In category: nemo
