Fast computations of Wasserstein gradient flows Abstract: Wasserstein gradient flows describe the evolution of a mass density flowing along a pressure gradient generated by an internal energy functional. This class of PDEs models various physical phenomena such as fluid flow, heat transfer, aggregation-diffusion and crowd motion. In general, these equations…

Title: Exploiting Mixed Precision Arithmetic in the Solution of Linear Systems Abstract: The emergence of low precision arithmetic on modern hardware, such as the increasingly supported fp16 and bfloat16 floating-point arithmetics, provides new opportunities to accelerate linear algebra computations. A key challenge in doing so is to preserve the accuracy…
