When I worked for a major hardware vendor, I had to port and tune several programs from this area, and the first and simplest way to get some performance usually was: - Formulate the algorithms in terms of BLAS (if the authors haven't done this already; usually they have). - Use the highest level BLAS that works (ideally that's level 3, and therefore dgemm). - Find the fastest BLAS for your machine and plug it in.
