What platform runs ASITIC best?

If you can compile an optimal version of BLAS locally, you will see very good performance. ATLAS can be used to generate such a library. Currently, the Linux version running on a Pentium II+ based system is the best. The reason for this stems from the fact that Intel has released their BLAS 3 level code which allows the LAPACK routines, used heavily in matrix inversions, to perform optimally. LAPACK code utilizes the cache to maximize throughput from memory into the CPU in order to run the FPU at maximum capacity. LAPACK cannot do this without some awareness of the underlying hardware. This awareness is provided by the BLAS level 3 code. While the Sun and HP versions of the code utilize the generic netlib FORTRAN implementation of BLAS, this code is non-optimal. If you possess BLAS code for your platform, please inform me and I can send you an optimized version of ASITIC. At UC-Berkeley we have access to the Sun High Peformance Library so I am able to dynamically link ASITIC with this
