We invite you to join us to watch the next SIAM Supercomputing Spotlights Webinar coming up on Wednesday, December 11 at 16:00 GMT in the VisLab (MCS 1022), held by the SIAM Activity Group on Supercomputing.

Title: Solving Big Problems with Little Numbers

Presenter: Hatem Ltaief, KAUST

Time: Wednesday, December 11, 2024,  

16:00 - 16:40 (30 min talk + 10 min questions)

Abstract

The future of simulations lies in leveraging hardware features designed for the AI market, particularly in low-precision computations. Modern NVIDIA GPUs exemplify this trend, offering significant performance gains through low-precision computations, resulting in reduced elapsed time, smaller memory footprints, and energy savings. We harness these capabilities to develop fast mixed-precision linear algebra algorithms. Our adaptive precision conversion strategy dynamically adjusts computation accuracy, maintaining high precision only where necessary within the matrix operator, while still meeting application-worthy precision requirements. This talk will illustrate how these algorithms revolutionize computational efficiency for geospatial statisticians, bioinformaticians, and geophysicists, having significant implications for environmental computational statistics, genome-wide association studies in computational biology, and seismic imaging for CO2 sequestration.
