[MITgcm-support] Compiling error for high resolution configuration

[Patrick Heimbach]

Hi there,

Goran is right.
This type of error message is typical if the executable doesn't fit
into memory (i.e. too large memory footprint).
Some compilers choke at compile time in the way you described, others  
don't,
but the executable will fail (I think with seg. fault).
You can kind of extrapolate by doing
size mitgcmuv
and look at the 4th number that you'll get.
You'll have to go multi-processor and chose a tile size that fits  
your memory.
