Summary
Implementing a parallel molecular dynamics as a parallel application presents some unique load balancing challenges. Non-uniform distribution of atoms in space, along with the need to avoid symmetric redundant computations, produces a highly irregular computational load. Scalability and efficiency considerations produce further irregularity. Also, as the simulation evolves, the movement of atoms causes changes in the load distributions. This talk describes the use of an object-based, measurement-based load balancing strategy for a parallel molecular dynamics application, and its impact on performance.
