Message-Passing Implementation of the Data Diffusion Communication Model in Fast Multipole Methods: Large Scale Biomolecular Simulations
Published 2008-12-01“…The algorithm maximizes locality of interprocessor communication by adopting to an arbitrary interconnection topology and at the same time takes multiprocessor nodes into account. The solution is incorporated into our implementation of the fast multipole method with periodic boundary conditions used for molecular dynamics simulations, but we believe it generalizes to many algorithms demonstrating an all-to-many communication pattern. …”

Adding SMP support to fastpaths in an L4 microkernel
Published 2015“…Fastpaths are a method of optimization which relies on treating the most commonly executed cases of certain functions in a privileged manner, such that behaviour is not modified, but execution time is reduced.Fastpaths play an important role on improving paravirtualization performance offered by an L4 microkernel.In this article we redesign two existing fastpaths in an L4 microkernel for the purpose of adding SMP support.We then put these fastpaths through a series of regression and performance tests to determine if the design is correct and what performance benefits we can expect by using them on a multiprocessor system.…”
