Description

Context

NEMO writes a lot of text diagnostics (some of the files are useful only for debugging). It looks that those diagnostics are responsible for NEMO performance degradation during RAID check observed at the MetOffice?. Tests with GO8 (based on NEMO4) showed that limiting amount of text data written during model run improves model performance during RAID check; see: ​http://forge.ipsl.jussieu.fr/nemo/attachment/wiki/user/andmirek/NEMO_IO_DIAGN.pdf

Proposal

This development will introduce different output levels for NEMO (0 - 4). For full diagnostics output (3) all data written currently by NEMO will be included. The amount of data written will decrease with decreasing output level. Old level 1 will correspond to new level 4.

with nn_print 3 as a default there will be no change in ocean.output and other text files compared to version before changes.
