The upgrades more than doubled the number of processors in the system, as well as Super s computing capabilities. Rankings on the list are determined by running benchmarking software a set of standardized tests to measure system performance on the supercomputer. In this round the IBM at Lawrence Livermore National Laboratory took top honors with a speed of 4,938 gigaflops. The UA machine, a Silicon Graphics Origin 2800, clocked in at 66.6 gigaflops. One gigaflops is a thousand million floating point operations per second.
Primary usage is by high-performance computing groups from engineering and scientific disciplines.
