Turns out, according to the authors, that they ARE using cards and CUDA that allows double-precision. Amazing.


In the following interesting article,

the authors " 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?
