You can also go for the INCITE or ALCC programs from the DOE: http://www.doeleadershipcomputing.org/ http://www.doeleadershipcomputing.org/ They award O(1 billion) hours to O(100) projects, and you don't need DOE funding to apply (or even be a US-based project). The catch is that your code has to be very scalable (to roughly 40k cores), and your science problems should be in line with the DOE mission.
