  3. Hardware roadmap As it looks to the future, the National Center for Computational Sciences expects to lead the accelerating field of high-performance computing. Upgrades will boost Jaguar’s performance to 250 teraflops by the end of 2007, followed by installation of two separate petascale systems in 2009.
