Subject:  Re: [PHP-DEV] GPU Acceleration
From: james.butler@edigitalresearch.com (=?windows-1252?Q?James_Butler?=)

As a slight side note, GPUs have been (and mostly still are) used for high performance workloads where squeezing as much useful 'work' per cycle is the order of the day. CUDA et al still hasn't hit the mainstream fully and is pretty niche. Unfortunately PHP being an interpreted language isn't going to be as efficient (yet=3F :-) ) as C or machine code and therefore you will lose some/alot of the advantage of going GPU.=20
However that is not a reason not to have a go (fork maybe=3F), something cool may come about from it. Nothing ventured, nothing gained.
