Shutdown
IBM Roadrunner was shut down on March 31, 2013. While the supercomputer was one of the fastest in the world, its energy efficiency was relatively low. Roadrunner delivered 444 megaflops per watt vs the 886 megaflops per watt of a comparable supercomputer. Before the supercomputer is dismantled, researchers will spend one month performing memory and data routing experiments that will aid in designing future supercomputers.
