GPU Supercluster

I was interested to see this GPU system doing some biologically inspired processing at Harvard.  Whilst I doubt that there will be any practical industrial applications to emerge from this, it does show how inexpensive it can be to build a minor supercomputer. To quote from their website...

...With peak performance around 4 TFLOPS (4 trillion floating point operations per second), this little 18”x18”x18” cube is perhaps one of the world’s most compact and inexpensive supercomputers....
