Well for one, I'd build a system architecture I first imagined back at Sun in the early 90's which is a NUMA fabric attached compute/storage/io/memory scalable compute node. Then I'd take a shared nothing cluster (typical network attached Linux cluster) and refactor a couple of algorithms that can "only" run on super computers and have them run faster on a complex that costs 1/10th as much. That would be based on an idea that was generated by listening to IBM and Google talk about their quantum computers and explaining how they were going to be so great. Imagine replacing every branch in a program with an assert that aborts the program on fail. You send 10,000 copies of the program to 10,000 cores with the asserts set uniquely on each copy. The core that completes kicks off the next round.
