NERSC Client Statistics

NERSC served 2,677 scientists throughout the United States in 2005. These researchers work in DOE laboratories, universities, industry, and other Federal agencies. Figure 1 shows the proportion of NERSC usage by each type of institution, while Figures 2 and 3 show laboratory, university, and other organizations that used large allocations of computer time. Computational science conducted at NERSC covers the entire range of scientific disciplines, but is focused on research that supports the DOE’s mission and scientific goals, as shown in Figure 4.
