[MITgcm-devel] testreport -noieee

[Jean-Michel Campin]

Hi,

I made some minor changes in testreport, replacing '-noieee' option 
with '-fast' (it still accepts '-noieee' but give a warning).
Also added option '-devel' and ignore -ieee option (since it's the 
default anyway).

In optfiles which are tested daily, the -ieee flags involve also
a lower optimisation in order to keep the results as close as
possible to the reference output (and I checked recently that, indeed,
with gfortran and ifort, if I switch to -O2 instead of -O0 
but keeping the same IEEE setting, a small number of experiments 
drift away from the standard output). 
But for a non-expert user, the main difference between using
-ieee or not, is the difference in optimisation, making the
2nd executable running much faster that the 1rst one.

I think that the new names "testreport -fast" and ".fast" suffix
on the testing web page are easier to guess what it means and also 
closer to what it is really.

Anyway, it would not be a big deal to switch back to -noieee if 
this is found to be a bad move (I would still keep the addition of
-devel anyway).

Cheers,
Jean-Michel
