Hi,
the Norwegian village idiot has finally realized that
running the code on several processors is a good idea.
After finally getting the code properly MPI-compiled,
I am stuck with a run-time error. After about 10
timesteps, the character variable buoyancyRelation
is changed from 'OCEANIC' to rubbish

The end of CALC_PHI_HYD.F is reached accordingly and the code stops.
STOP CALC_PHI_HYD: We should never reach this point! statement executed
Any ideas?
The version used is checkpt40pre5 and it is run on an SGI Origin 3000.
The domain is 16 x 64 x 64. The error does not occur if
the coMPIlied coed is run on a single processor.
Below are the first few lines of the Makefile.
