[{"abstract":[{"lang":"eng","text":"<jats:p> 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 4400 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. </jats:p>"}],"publication":"The International Journal of High Performance Computing Applications","keyword":["Hardware and Architecture","Theoretical Computer Science","Software"],"language":[{"iso":"eng"}],"year":"2023","quality_controlled":"1","title":"Breaking the exascale barrier for the electronic structure problem in ab-initio molecular dynamics","publisher":"SAGE Publications","date_created":"2023-05-30T09:19:09Z","status":"public","type":"journal_article","article_number":"109434202311776","article_type":"original","_id":"45361","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"27"},{"_id":"518"}],"user_id":"75963","citation":{"ieee":"R.
