I have not used it - nor have I seen much documentation, but the 
Graphite branch of GCC supports shovelling loops to the GPU via OpenCL.

I have to admit I have not seen much documentation for it, just the talk 
at 
http://gcc.gnu.org/wiki/summit2010?action=AttachFile&do=get&target=belevantsev.pdf

Thus, I cannot comment on how to use it nor how well it performs. Others 
might know better.
