FORTRAN90/OpenMP version 0.10.18
FORTRAN90/OpenMP-Coarray version 0.12.20
A newtonian dynamics program.
written by Ross J. Stewart
This is a molecular dynamic program that is multithreaded for use on shared memory machines. There are two versions of this program, the OpenMP only version in ./src/ and a hybrid parallel version using both OpenMP for shared memory and Open-Coarray-Fortran for distributed memory on massively parallel archetectures in ./src_CAF. Open-Coarray-Fortran (CAF) is in some ways a compiler-level wrapper around the MPI library. The CAF version requires the model domain to be decomposed using the code in ../DomDec. Many of the included examples makes use of the crystal tesselation coce in ../tessel. This code only utilizes particle pair potentials, no multibody potentials like Tersoff or EAM have been enabled.
