NERSCPowering Scientific Discovery Since 1974

Who We Are

As one of the world’s premier supercomputing centers, NERSC supports perhaps the largest and most diverse research community of any high-performance computing facility, providing large-scale, state-of-the-art computing for DOE’S unclassified research programs. More than 6,000 scientists worldwide use NERSC to conduct basic and applied research in energy production and conservation, climate change, environmental science, materials research, chemistry, fusion energy, astrophysics and other areas related to the mission of the DOE Office of Science. 

But NERSC is much more than a facility full of computers, servers, routers and software tools. One of its most valuable attributes is its staff, a talented collection of computer scientists, mathematicians, engineers and support personnel. More than half of NERSC staff hold advanced degrees in a scientific or technical field. And collaboration— “team science”, a concept pioneered by Berkeley Lab founder Ernest O. Lawrence in 1931—is a cornerstone of NERSC’s philosophy, both internally and through its engagements with the broader science community. 

NERSC is divided into groups designed to serve the varied needs of its users and maintain the highest quality supercomputing infrastructure possible. There is also a dedicated Cray support team at the center.
