This page documents a reference run completed with FOAM 1.5.50.

You should use the output from this run to compare against your favorite cluster or computation platform to see if differences in compilers and processor produce unacceptable changes in the simulated climate.

Reference run characteristics:

  • FOAM Version: 1.5.50
  • Machine: blueice at NCAR, IBM Power5+
  • Compiler: xlf 10.1
  • Compiler options:
    • Fortran: -O3 -qstrict -qarch=auto
    • C: -O3 -qstrict -qarch=auto
  • Run Length: 100 years from initial run.
  • History frequency: 30 days
  • I/O format: NetCDF
  • Initial data: ncfoam1.5datR15_128.single.tar
  • Atmosphere settings: modern.
  • number of processors: 32
  • Co-located.

FOAM compiler options used: 

    FOAM_OPTS = -DOCEAN_LAT_PROCS=4\
       -DOCEAN_LON_PROCS=8\
       -DATMOS_LAT_PROCS=4\
       -DATMOS_LON_PROCS=8\
       -DCOLOCATED_OCEAN -DNETCDF\
       -DCSIMICE -DDAY_TIMER -DFORCEHY\
       -DPP_RHOMB_TRUNC=15 -DSIMPLE_OUTPUT\
       -DWORD4 -DPP_MPI -DCOUPLED -DREAD1_5

The reference run, all 100 years of monthly data from atmosphere, ocean and coupler, can be downloaded from [1]. (Use anonymous ftp)

See the atmos_params file there: [2] for exact atmosphere settings.

When producing your own run, we strongly recommend keeping as many settings as possible identical. This includes the number of processors FOAM is compiled for.
