The ability to perform long, accurate molecular dynamics (MD) simulations involving proteins and other biological macro-molecules could in principle provide answers to some of the most important currently outstanding questions in the fields of biology, chemistry and medicine. A wide range of biologically interesting phenomena, however, occur over time(More)
Anton 2 is a second-generation special-purpose supercomputer for molecular dynamics simulations that achieves significant gains in performance, programmability, and capacity compared to its predecessor, Anton 1. The architecture of Anton 2 is tailored for fine-grained event-driven operation, which improves performance by increasing the overlap of(More)
One of the major design verification challenges in the development of Anton, a massively parallel special-purpose machine for molecular dynamics, was to provide evidence that computations spanning more than a quadrillion clock cycles will produce valid scientific results. Our verification methodology addressed this problem by using a hierarchy of RTL,(More)

Proximal hamstring origin avulsions are rare injuries. A common cause for this kind of injury is a trauma with the hamstring in overextension and simultaneously forced hip flexion and knee extension. We report on 6 cases, 5 with an acute rupture of the hamstring origin and one case with a delayed presentation in our emergency room. In 3 cases the injury was(More)
