As others have noted, wide availability, low cost (driven by the gaming
market), and existing toolkits have favored using GPUs, which typically have
several FPUs on board. Some tinkering is required to get the best performance,
based on a talk I heard recently. A current limitation is that most of the FPUs
are single precision (32-bit f.p.), which is sufficient for graphics rendering.

It seems that there is beginning to be significant efforts to do processing
using video card processors. Could someone comment on this as to why this
is being so successful [probably many factors, I suppose], what kinds of
computations work well on them, and what kinds of work probably do not work
well on them.... and why?
