[MITgcm-support] reducing the size of STDOUT files etc

[Jonny Williams]

Hi again

I think I've found the main culprit for what was giving me so much output.
In my run directory there is a file called eedata with the following
contents...

# Example "eedata" file
# Lines beginning "#" are comments
# nTx - No. threads per process in X
# nTy - No. threads per process in Y
 &EEPARMS
 nTx=1,
 nTy=1,
 *debugMode=.FALSE.,*
 &
# Note: Some systems use & as the
# namelist terminator. Other systems
# use a / character (as shown here).

Previously the debugMode was set to false. Changing this to false has
dramatically cut down the size of the output files.

I'd still like to be able to write to one STDOUT and one STDERR file if
possible though (see my previous email!).

Thanks again

Jonny
