[Mitgcm-support] mitgcm with limited memory

[mitgcm-support at dev.mitgcm.org]

Hi Alistair and Chris,

maybe one you can give me a tip on running the model (r1b1) with limited 
memory.

I try to start a model with 450 x 210 x 30 on a DEC Alpha with 2GB 
memory. To the best of my knowledge the model would need (using real*4) 
abouth 1.3GB. But even if I
- compile the code with option "r4"
- undefine REAL4_IS_SLOW in CPP_EEOPTIONS.h
- define _RL as Real*4

it still does not fit. Any suggestions/tips here?

-Arne
