1) I have never seen great performance from FPGAs (with the possible
exception of GRAPE). I would strongly
    encourage you to rethink this plan, and instead go with something like a
CUDA solution.

2) Software already exists to do dense linear algebra on GPUs, and would be
easy to integrate with our
    existing dense matrix implementation.
