Maybe Phi won't be that expensive (beware your mail program might break the link in two): http://www.brightsideofnews.com/news/2012/9/26/exclusive-intel-xeon-phi-preferred-pricing-revealed---only-24400-per-card.aspx Also, I assume we'll be able to use it with OpenCL. As soon as there's drivers for it, we already have an implementation supporting it! Then again, we do not have code really optimised for it. magnum
