In this video from PASC18, David Bader from Georgia Tech presents: Massive-Scale Analytics Applied to Real-World Problems. “Emerging real-world graph problems include: detecting and preventing disease in human populations; revealing community structure in large social networks; and improving the resilience of the electric power grid. Unlike traditional applications in computational science and engineering, solving these […]
In this video from PASC18, Yves Robert from École normale supérieure de Lyon in France presents: Recent Results and Open Problems for Resilience at Scale. “The talk will address the following three questions: (i) fail-stop errors: checkpointing or replication or both? (ii) silent errors: application-specific detectors or plain old trustworthy replication? (iii) workflows: how to […]
In this video from PASC18, Tristan Konolige from the University of Colorado Boulder presents: A Parallel Solver for Graph Laplacians. “Problems from graph drawing, spectral clustering, network flow and graph partitioning can all be expressed in terms of graph Laplacian matrices. There are a variety of practical approaches to solving these problems in serial. However, […]
In this video from PASC18, Etienne Lyard from the University of Geneva, Switzerland presents: Handling and Processing Data from the Cherenkov Telescope Array. “The Cherenkov Telescope Array (CTA) will be the world’s largest and most sensitive high-energy gamma-ray observatory. Composed of more than 100 telescopes of different sizes between 4 and 23 meters in diameter, […]
In this video from PASC18, Christian Engelmann from Oak Ridge National Laboratory presents: Characterizing Faults, Errors and Failures in Extreme-Scale Computing Systems. “Building a reliable supercomputer that achieves the expected performance within a given cost budget and providing efficiency and correctness during operation in the presence of faults, errors, and failures requires a full understanding […]
