[MITgcm-support] Errors with eedata and eeset_parms

[Jonathan Lauderdale]

Hi Katie,

When you ran genmake, did you also use the “-mpi” flag? Then when you go to execute the model, as Kaveh mentioned, you’ll need:

> mpirun -np 12 ./mitgcmuv


i.e. requesting the same number of cores as tasks.

Cheers,

Jonathan
