See the r-devel archives for August where Doug Bates started a thread
[Rd] Compiling R for the Sony Playstation 3
with many posts.
The upshot,as I recall, is the he 'simply' installed Ubuntu on his PS3 in
order to real software (read: Emacs, R) running on his 'dvd player' as he
calls it.
There is a lot of interest in making R work on things like the Cell as well
as in GPGPU frameworks, at least for subroutines and libraries (and I
understand that some work is ongoing in that area). The main R thread will
probably remain single-threaded 'forever'. Others may have more pertinent
comments.
Hope this helps, Dirk
