[MITgcm-devel] linux_amd64_ifort+mpi_ice_nas update

[Jean-Michel Campin]

Hi David & Dimitris,

The reason I was asking is that there is a fair amount of computation
in seaice_growth.F, -O0 is slow (even sometimes very slow),
so may be if it could go through -O1 it could speed up the runs.

> Could this be tested with testreport first?
Sounds like a good suggestion. We have few experiments that use
seaice_growth.F, not testing everything but should be 
a good start.

Cheers,
Jean-Michel
