In conjunction with the constellation, Rensselaer operates the Center for Computational Innovations which is the result of a $100 million collaboration between Rensselaer, IBM, and New York State to further nanotechnology innovations. The center is currently home to the most powerful private-university based supercomputer in the world and its supercomputer is consistently ranked among the most powerful in the world, capable of performing over 1.1 peta-FLOPS. The center's main focus is on reducing the cost associated with the development of nanoscale materials and devices, such as used in the semiconductor industry. The university also utilizes the center for interdisciplinary research in biotechnology, medicine, energy, and other fields. Rensselaer additionally operates a nuclear reactor and testing facility – the only university-run reactor in New York State – as well as the Gaerttner Linear Accelerator, which is currently being upgraded under a $9.44 million grant from the US Department of Energy.
