Orca is slated to be changed to appear Graham-like. When that happens, the orca compile flags given here will not work.

MITgcm Configuration Files

The MITgcm source code needs to be compiled with settings appropriate for whichever platform it will be run on. Each platform has a corresponding configuration file. These configuration files are included in the MITgcm bundle you pull from the UW git repository. You'll see them under /path/to/MITgcm/tools/build_options/. The file names reflect the hostnames of the servers.

The makempi.sh script uses these configuration files and sets appropriate flags and load modules in order to compile MITgcm on the Fluids Group's servers and on Compute Canada (a.k.a. The Alliance) servers.
