[MITgcm-support] ifort/g77 issue

[Thomas Haine]

Hi Folks, 

I have an ifort/g77 issue on dolphin (x86_64, linux 2.6.9-55.0.6.ELsmp)
using checkpoint59m (and an old checkpoint too):

Building with linux_amd64_ifort I get theta blowing up in 3-10 steps (in
1 step it rises to O(10^3)). The exact details are not reproducible.

Building with linux_amd64_g77 gives no problem.

I get similar problems with ifort+mpi, where increasing OLx,OLY from
3->4 seems to stabilise the problem (not fully explored).

I have: gcc version 3.4.6 20060404 (Red Hat 3.4.6-8), ifort Version
10.0. My pkg/data configuration is very simple.

Any ideas?

Cheers, Tom.
