CRD, NERSC Staff Present at SIAM Conference on Parallel Processing for Scientific Computing

February 18, 2014


Dozens of scientists from Berkeley Lab’s Computational Research and National Energy Research Scientific Computing divisions are presenting their research this week at the Sixteenth Conference on Parallel Processing for Scientific Computing. Sponsored by the Society for Industrial and Applied Mathematics, the conference series has played a key role in promoting parallel scientific computing, algorithms for parallel systems and parallel numerical algorithms. The conference is unique in its emphasis on the intersection between high performance scientific computing and scalable algorithms, architectures, and software. This year’s meeting is being held Feb. 18-21 in Portland, Ore. Lenny Oliker of CRD’s Future Technologies Group was a member of the organizing committee.
