Scripting languages such as Python and Tcl are a powerful tool for the construction of flexible scientific software because they provide scientists with an interpreted problem solving environment and they provide a modular framework for controlling s

Toxoplasmosis is caused by the protozoan organism, Toxoplasma gondii. Infection with this organism primarily results from contact with infected cats and from ingestion of improperly cooked meat. Most adults with toxoplasmosis are asymptomatic. When s

We have performed massively parallel 3D molecular dynamics simulations with up to 35 million atoms to investigate ductile failure, obtaining mechanistic information at the atomistic level inaccessible to experiment. We observe dislocation loops emitt

We have discussed the prospects of applying massively parallel molecular dynamics simulation to investigate brittle versus ductile fracture behaviors and dislocation intersection. This idea is illustrated by simulating dislocation emission from a thr

We present a new scalable algorithm for short-range molecular dynamics simulations on distributed memory MIMD multicomputers based on a message-passing multi-cell approach. We have implemented the algorithm on the Connection Machine 5 (CM-5) and demo

We outline a recently developed short-range molecular dynamics (MD) algorithm for message-passing MIMD computers. Timings and performance numbers are presented for a code, SPaSM, which implements the algorithm on the Connection Machine-5 (CM-5). We d

We have studied brittle and ductile behavior and their dependence on system size and interaction potentials, using molecular-dynamics (MD) simulations. By carefully embedding a single sharp crack in two- and three-dimensional crystals, and using a va
