[Rd] Cell or PS3 Port

Hello,

I am interested in optimizing some of R's vector math functions to utilize the SPE units of the Cell processor (commonly found in the Playstation 3) and I am wondering if anyone has already done any work in that area. I can't find anything using the search page or Google. (Admittedly it is difficult to search for information on a one-letter-named programming language whose contributed documentation intrinsically refers to "cells" frequently. :) I'm assuming it will be possible to compile R under a PS3 version of Linux, since it has a ppc64 architecture and R already runs on OS X. Are there any known caveats to compiling R for a distro like Ubuntu with X11 support?

I'm just going through the Cell SDK documentation at this point so it will be a few days before I really get into the guts of it. Any information would be greatly appreciated.

-Ed
