'The remarkable thing about KASY0's price/performance is that, while network hardware is often the dominant cost for a system of its size (128 plus 4 spare nodes), less than 11% of the system cost went for the network hardware. The AMD Athlon XP 2600+ processors were more than 35% of the total system cost; memory was 21%. Even more significantly, the network design technology that made this possible can be applied with similar benefit to cluster supercomputers with thousands of nodes. KLAT2's network was the world's first Flat Neighborhood Network; the enhanced version used for KASY0 is the world's first Sparse Flat Neighborhood Network (SFNN). KASY0 also is the first supercomputer to have its physical node and switch placement optimized by a computer program. FNN design technology and tools have been freely available and used by various other groups; so too will the new SFNN technology be freely available.'
