In the following interesting article,
http://www.biomedcentral.com/1756-0500/2/149
the authors "...show that a single GPU machine containing three GPUs
that costs $2000 performs similarly to 150 CPUs on a compute cluster.
These CPUs, including the added infrastructure and support cost of the
cluster system, would cost approximately $82,500."
Occasionally I ask Stata Corp about the possibility of parallel
computing using graphics processing chips, for example:

The problem seems to be that GPUs do not generally support double-
precision arithmetic. I guess one question for the authors of the
above article is: fast yes, but precise?
