Thanks, Richard.  Good find!  I think you do numerical computing as well --
have you done any of this?  I've seen GPU implementations for solving sparse
and dense linear systems -- which is, essentially, solving partial
differential equations using implicit discretization methods.  You do this
in your own work, don't you?

In my own work with finance, I'd be interested in the FFT, high performance
sorting and database work (which I just found in that link you mentioned!)
I've also been thinking of extending my dissertation work, solving the
Schrodinger-Newton PDE in 2 and 3 dimensions.

I'm not entirely sure why, but every paper I've read on the subject, so far,
uses NVidia hardware.  Need to do more reading to find out why...
