Mixed-Precision Computing for Scientific Discovery: Formats, Co-Design, and Responsible Approximation
Emmanuel Agullo, Hartwig Anzt, Daniel Bauer +37
Reduced and mixed precision have moved from a niche optimization to a central design axis in scientific computing and engineering, driven by energy constraints, heterogeneous accel…
TERRA-NG v1.0: Extreme-Scale, GPU-accelerated Mantle Convection
Fabian Böhm, Nils Kohl, Ponsuganth Ilangovan +7
We present TERRA-NG, a portable, GPU-accelerated, matrix-free mantle-convection code. A single Kokkos C++ implementation runs at scale on NVIDIA, AMD, and Intel GPU supercomputers.…
Performance Analysis of Low-Order, GPU-accelerated Finite Element Kernels using Kokkos
Fabian Böhm, Nils Kohl, Harald Köstler +1
We study performance portability for low-order, matrix-free finite element kernels, using the example of a vectorial, variable-coefficient PDE operator originating in geophysical m…
