[MITgcm-support] Re: MIT model (c19) from JPL

[heimbach at mit.edu]

Hi Elena,

the JPL code based on c19 is fairly old and has 
considerably departed from the MITgcm main version
so it's a bit hard for me to judge.

Nevertheless, one immediate guess is the 
big/little Endian issue for PC clusters.
Here are a few things you could try:
* if you're compiling with g77 or ifc, add the following CPP option
  to your DEFINES list: -D_BYTESWAPIO
* if you're compiling with pgf77, add the following compiler option
  to your FFLAGS list: -byteswapio
A collection of CPP & compiler options for various platforms
can be found at 
http://dev.mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm/tools/build_options/

If you find out that that's not the problem,
let us know and give more details as to what goes wrong.

Cheers
-Patrick
