I am doing some neural network processing, which involves a lot of floating-point calculations. I have seen a few floating-point accelerator boards advertised which claim to provide performance in excess of 8 Mflops for $2-5K. Viewed superficially, this performance would put them in competition with one of the IBM RISC workstations, located down the hall. These boards allow the compilation and execution of code entirely on the board, or execution on the Mac, with embedded function calls to library functions on the board. Does anyone have experience with any of these boards? Do they live up to their performance claims? Are they well integrated with the Mac environment? Can existing code be easily migrated? Is assembly language expertise required to achieve those claims, etc? Steve Diamond Johns Hopkins Univ. Applied Physics Laboratory
