[MITgcm-support] Compiling for tutorial_baroclinic_gyre

[Martin Losch]

Hi Kirk,

I think, within directory ~/mitgcm/MITgcm_c63f/verification/tutorial_baroclinic_gyre/build
/home/kbryan/mitgcm/MITgcm_c63f/tools/genmake2  -mods ../code
should work, and ../code also contains an appropriate SIZE.h (I think the error message is a result of not specifying the -mods ../code, where the configuration specific files reside, this is absolutely necessary). 
genmake2 usually can guess an appropriate optfile by itself. In your case it picked linux_ia32_f77.
If you want to specify a different optfile, you can (according to the compiler and platform that you have) choose from /home/kbryan/mitgcm/MITgcm_c63f/tools/build_options

For a single tile configuration you can change this:
sNx=60,
sNy=60,
nSx=1,
nSy=1,
The buffer width is specified by olx/oly, and a value of 2 (as in ../code/SIZE.h) is enough for the choice of advection schemes etc. in this tutorial.

You might also want to have a look at
http://mitgcm.org/public/r2_manual/latest/online_documents/node117.html
(in particular 3.10.5.3) although not quite up to date, I am afraid.

Martin
