Whatever, dot product or element-wise product. Both are memory-bounded.

As Francesc previous said, these need to be at least in double precision
and really it should also be in all the floating point precisions used
by numpy on supported platforms. Based on the various boinc project
comments, many graphics cards do not natively support double precision
so you can get an inflated speedup just because of the difference in
precision.
