DESCRIPTION:Posters, Research Posters\n\nPoster 64: 416-PFLOPS Fast Scalab
le Implicit Solver on Low-Ordered Unstructured Finite Elements Accelerated
by 1.10-ExaFLOPS Kernel with Reformulated AI-Like Algorithm: For Equation
-Based Earthquake Modeling\n\nIchimura, Fujita, Yamaguchi, Naruse, Wells..
.\n\nWe propose herein an approach for reformulating an equation-based mod
eling algorithm to an algorithm similar to that of training artificial int
elligence (AI) and accelerate this algorithm using high-performance accele
rators to reduce the huge computational costs encountered for physics equa
tion-based modeling in earthquake disaster mitigation. A fast scalable equ
ation-based implicit solver on unstructured finite elements is accelerated
with a Tensor Core-enabled matrix-vector product kernel. The developed ke
rnel attains 1.10 ExaFLOPS, leading to 416 PFLOPS for the whole solver on
full Summit. This corresponds to a 75-fold speedup from a previous state-o
f-the-art solver running on full Piz Daint. This result could lead to brea
kthroughs in earthquake disaster mitigation. Our new idea in the HPC algor
ithm design of combining equation-based modeling with AI is expected to ha
ve broad impacts in other earth science and industrial problems.\n\nRegist
