(SN-1) which was the "b" machine, nicknamed bubbles because of the bubbles visible in the fluid of its unique direct liquid cooling system. In the early eighties, CTRCC's name was changed to the National Magnetic Fusion Energy Computer Center or NMFECC. The name was again changed in the early nineties to National Energy Research Supercomputer Center. In 1996 NERSC moved from LLNL to LBNL. In 2000, it was moved to its current location in Oakland.

Computers and projects

NERSC's fastest computer, Hopper, a Cray XE6 named in honor of Grace Hopper, a pioneer in the field of software development and programming languages and the creator of the first compiler. It has 153,308 Opteron processor cores and runs the Suse Linux operating system.

Other systems at NERSC are named Franklin, Carver, Magellan, Dirac, Euclid, Tesla, Turing, and PDSF, the longest continually operating Linux cluster in the world. The facility also contains a 8.8 petabyte
