Good idea. You might also want to try "Goto BLAS" (Google that to find the free download site). It can be compiled for a different architecture a lot quicker than ATLAS, and provides very good performance for both Intel and AMD architectures. As you may have already found, once you are using a good BLAS library with HPL, various compilers or compiler options won't make much difference in performance. -Tom
