Lucky Tokens

NERSC’s Hopper supercomputer contained 153,216 compute cores, 217 terabytes of memory, 2 petabytes of disk storage—and a cat figurine for luck!

Hopper, named in honor of computer scientist Grace Murray Hopper, had a Japanese "lucky cat" figurine stashed in one cabinet. In April 2011, Yukiko Sekine (NERSC's former Energy Department program manager) presented the cat to Jonathan Carter (currently associate lab director for the Computing Sciences Area).

It’s not the first lucky token to stand guard over NERSC’s large, complex, and well-used scientific supercomputers. Other systems – for reasons known only to NERSC staff – have been protected from ill fate by rubber chickens. (»Visit our interactive timeline to learn more about NERSC history.)
