Richard Fateman asks if a hardware accelerator speeds up Mathematica very much. He points out that it does thousands of instructions for every floating point instruction. This observation is correct. However, there are built-in functions that Mathematica does differently. For example if you invert a matrix of all machine floats, Mathematica copies the numbers into a separate area, then calls the Linpack routine DGEDI. For this, an acclerator will help a lot. -- David Jacobson
