As part of the Exascale Computing Project (ECP), a collaborative team of scientists, software developers, and hardware integration specialists from across the Department of Energy (DOE) has developed the Exascale Atomistics for Accuracy, Length, and Time (EXAALT) application to bring molecular dynamics (MD) into the exascale era. Danny Perez, a physicist within the Theoretical Division at Los Alamos National Laboratory and the project’s principal investigator says, “We’ve implemented new scalable methods that allow us to access as much of the accuracy, length and time space as possible on exascale machines by rethinking our methods and developing algorithms that go around some of the bottlenecks that limited scaling previously.” Such a capability has potential to revolutionize MD.

Computationally, EXAALT’s goal is to develop a comprehensive molecular dynamics capability for exascale. "The user should be able to say, ‘I’m interested in this kind of system size, timescale, and accuracy,’ and directly access the regime without being constrained by the usual scaling paths of current codes,” said Danny Perez of Los Alamos National Laboratory (LANL) and the EXAALT team.

"The Amber Molecular Dynamics software is a well known and understood application for the structural dynamics of large biological molecules. With modern computer systems, a speedup in the computations can lead to studying events that occur on longer timescales, as well as statistical convergences. By incorporating the Intel Xeon Phi coprocessor into the workflow on a compute server, additional speedups can be obtained."
