American computer scientist Grace Hopper will power science on the cabinets of the National Energy Research Scientific Computing Center's (NERSC) petascale Cray XE6 system.  A pioneer in the field of software development and programming languages, Hopper created the first compiler. She was a champion for increasing the usability of computers, understanding that their power and reach would be limited unless they were made to be more user-friendly. NERSC's new flagship machine is named "Hopper" in her honor.

Cray launched the XE6 supercomputing system last week at its annual gathering of users in Edinburgh, Scotland. The Hopper system is being deployed at NERSC in two-phases—last year the system arrived as a Cray XT5 and over the next few months will be upgraded to a petascale XE6 system.

The new flagship system will feature Cray’s new Gemini interconnect, which will improve performance of scientific applications as well as system reliability and resilience. Phase-2 will also incorporate innovative ECOphlex liquid cooling technology, which will increase the machine’s energy efficiency.

"At NERSC, we serve a diverse scientific workload and a large user base that includes more than 3,000 scientists and engineers performing a wide array of unclassified research. Our center needed a supercomputing system that is energy efficient and delivers outstanding performance on real-world applications and we're looking forward to making a petascale system using Cray's latest technology available to our broad user community as they tackle some of the most critical problems facing society today, such as cleaner energy and climate change," said Kathy Yelick, Director of NERSC at Lawrence Berkeley National Laboratory.
