[MITgcm-support] optim.x compilation

[Samar Khatiwala]

Hi Matt,

A wild guess: don't you need to compile BLAS on ranger to use optim?  
(I think its needed by the CG solver in the L-BFGS algorithm.)

BLAS performance is not critical for this, but you might as well link  
to the optimized version available in the
AMD acml library on ranger. Add this to your .login_user file:

module load acml

Then you can link against:

/opt/apps/pgi7_1/acml/4.0.1/pgi64/lib/libacml.a

or (safer)

$TACC_ACML_LIB/libacml.a
