I assume this is a bottom post list, so my answers are below...

OK, this is good to know.

Per the instructions in the README file.

This is what I have for my site.cfg file:

include_dirs = /u/users/tky/mklinc
library_dirs = /u/users/tky/mkllib
mkl_libs = mkl_sequential,mkl_intel_lp64,mkl_core
lapack_libs = mkl_sequential,mkl_intel_lp64,mkl_core

I am using MKL 11 update 3, which uses a different set of libraries for linking.  Where do I set ATLAS=1?
