TL;DR: Anton 3 as mentioned in this paper is the fastest supercomputers in the world, achieving an order-of-magnitude improvement in time-to-solution over its predecessor, Anton 2, and is over 100 times faster than any other currently available supercomputer.
Proceedings ArticleDOI
Radix-8 Digit-by-Rounding: Achieving High-Performance Reciprocals, Square Roots, and Reciprocal Square Roots
TL;DR: A high-performance digit-recurrence algorithm for computing exactly rounded reciprocals, square roots, and reciprocal square roots in hardware at a rate of three result bits -- one radix-8 digit -- per recurrence iteration is described.
Proceedings ArticleDOI
Tight Certification Techniques for Digit-by-Rounding Algorithms with Application to a New 1/sqrt(x) Design
TL;DR: A rigorous, computer-aided method for correctness certification that better approximates the necessary conditions, lowering the risk of rejecting correct designs and two specific applications of this method are presented.
Proceedings ArticleDOI

TL;DR: In this paper, the authors integrate Newton's laws of motion into a model of the force field, and compute forces on every atom based on current positions and velocities and positions in discrete time steps.
