DESCRIPTION:Scaling the “Memory Wall” for Multi-Dimensional Seismic Proces
 sing with Algebraic Compression on Cerebras CS-2 Systems\n\nWe exploit the
  high memory bandwidth of AI-customized Cerebras CS-2 systems for seismic 
 processing. Through low-rank matrix approximation, memory hungry seismic a
 pplications fit onto memory-austere SRAM waferscale hardware, addressing a
  challenge arising in many wave-equation-based algorithms that r...\n\n\nD

 Turbulent Rayleigh–Bénard Convection through Unprecedented Spectral-Elemen
 t Simulations\n\nWe detail our developments in the high-fidelity spectral-
 element code Neko that are essential for unprecedented large-scale direct 
 numerical simulations of fully developed turbulence. Major innovations are
