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

[Dustin Carroll]

Hi Jonny,

You can also set debugLevel = -1 in your data file to reduce output. I use this to save on file space once my model is tested and stable.

Cheers,
Dustin

This appears to be an overkill for a “production” run (where you don’t test things any longer), will make the model very slow and the STDOUT-files very large. For a production run I usually use a monitorFreq = 20-50*deltaT.

I thought that running with useSingleCpuIO=.TRUE. should mean that I only get 1 STDOUT file? I've attached my data file in case anyone has any ideas as to what is going wrong?!
