LANS Informal Seminar: Barry Smith

Seminar Title: GPUs, Why They Are So Important and Why Everyone Hates Them
Speaker: Barry Smith, Senior Computational Mathematician, MCS/ANL
Date/Time: 2020-02-12 10:30
Location: Bldg. 240, Rm. 4301
Description:
GPUs will come to dominate the mid to high range of numerical simulation within the next few years. Both Oak Ridge’s and Argonne’s first exascale computers will be powered by GPUs. I will discuss at a cartoon level what architectural features make them inevitable for numerical computations and how these same features and other attributes make them so disliked by most developers of numerical simulation applications and libraries.
