Exactly, that is another facet of the same debate about the future:
the need for a shift that encompasses both programming language, execution
model and interconnect hardware.

I would go for virtualizing the cluster as single system (virtual SMP) and then

Yes, the petroleum industry is using GPUs in production. At Hess Corporation,
we have our main seismic imaging codes running in production on nvidia GPUs. I
have several presentations you can find on the internet, if you want details.
There are several other companies with some similar success

Its their own new proprietary interconnect, runs at 80Gb/s (similar
speed to IB 8x), switches are low port count. What the article missed is
that they are also using their own CPUs and host chipset (along with
Intel) in that system as well.
