Breaking the Exascale Barrier for the Electronic Structure Problem in Ab-Initio Molecular Dynamics

R. Schade, T. Kenter, H. Elgabarty, M. Lass, T. Kühne, C. Plessl, in: arXiv:2205.12182, 2022

The non-orthogonal local submatrix method applied to electronic-structure based molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32 mixed floating-point arithmetic when using 4,400 NVIDIA A100 GPUs of the Perlmutter system. This is enabled by a modification of the original method that pushes the sustained fraction of the peak performance to about 80%. Example calculations are performed for SARS-CoV-2 spike proteins with up to 83 million atoms.
