# These are the build options used with the Intel 10.x compiler for |
| 7 |
# testing on Beagle (with and without MPI). |

# Use after |

# module add mitgcm |
| 12 |
# |
| 13 |
# (tested with darwin/20090605 mitgcm/20090605, i.e., |
| 14 |
# intel/10.0.025 mx/1.0 netcdf/3.6.2/intel-10.0.025 mpich-mx/1.2.7..7/intel-10.0.025) |
| 15 |
# |
| 16 |
# These modules set FFLAGS, CFLAGS and CPPFLAGS for mpich and netcdf. |
| 17 |
# |
| 18 |
# The SGE -V option for exporting environment variables may also be |
| 19 |
# helpful if you encounter missing-library problems. Or, |
| 20 |
# alternatively, one may choose to link with one of the intel |
| 21 |
# "-static" or "-i-static" flags. |
