Statement of Significance

ParSplice is a molecular dynamics method for parallel-in-time trajectory generation, allowing this workhorse of in silico science to strong scale on massively parallel computers. Trajectories generated by ParSplice always have robust theoretical guarantees on their validity, with parameter choices only affecting the parallel efficiency. This commentary summarizes the ParSplice approach with minimal mathematical development, emphasizing how the theoretical underpinning is essential for deployment at the exascale.
