Welcome. Toni Cortes

Storage in an  Exascale World

Keynote by Rob Ross

Abstract: Storage systems play a crucial role in high-performance computing, providing a fault tolerant repository for application state and holding the results of simulations for future analysis. Without robust storage systems, high-performance computing applications would fail to deliver new discoveries. As supercomputing pushes into the exascale regime, systems will reach unprecedented levels of concurrency, complexity, and rate of computation, dramatically widening the gap between simulation and storage capabilities. To meet the needs of exascale applications, future storage systems must break from business as usual.
