floating point operations.  There isn't very much support in SBCL itself
to vectorize operations automatically, so the first step might be to
define some high-level functions (e.g. a dot-product or a fourier
transform) and write the machine instructions to execute that on the
processor board.  (But I could be very wrong about what this is for.)

In regard to dot product and other linear algebra computations, a starting point might be to look at whether anyone has written/is writing a BLAS/ATLAS library for it.  That would be worthwhile for anyone needing to do linear algebra regardless of language.
