If I used gfortran, could I manually insert a few basic OMP

I'd suggest using a third-party threaded library for now, unless
threaded, parallel solvers is your research topic. It's a large
design space that hasn't been mapped well, and the current CGETRF
needs some work before hand-threading gives better performance
than just using a threaded CGEMM from an external BLAS.
The UTK folks have plans in that area, but I don't know them well
enough to describe them.
