Short Introduction: Scientists are drowning in data. The scientific data produced by high-fidelity simulations and high-precision experiments are far too massive to store long term. The unwieldy nature of the data makes it difficult to analyze or to retain for future analysis or comparison. Data compression is a necessity, but there are surprisingly few options […]

SC15 Invited Talk-Dr. Laura Grigori Presents Fast and Robust Communication Avoiding Algorithms: Current Status and Future Prospects
Left: computation to communication ratio for the LU factorization with partial pivoting of a dense matrix on a model of exascale machine (ISC 2014). Right: preconditioned Krylov solver as used in the map making problem in astrophysics, results obtained on a Cray XE6 machine (Astronomy and Astrophysics, 2014). Please click to enlarge. This talk will […]
