[MITgcm-support] Limitation for Tile's dimensions

[Patrick Heimbach]

Eli,

this type of error message is typical for a setup
in which your executable size per processor exceeds the memory limit.
At the link stage some compilers then choke with this type of error  
message.

Two options to test this:
1) Just drastically reduce dimensions in SIZE.h
    and see whether it compiles.
    (should be easy to do).
2) If you have access to more processors,
    see whether you can fit it on more processors.

-Patrick
