Topic: Parallelizing an application

Pick another parallel application, not covered in the text, and less than 7 years old, and describe the various steps in parallelizing it (decomposition, assignment, orchestration, and mapping). You may use an example from the peer-reviewed literature, or a Web page. You do not have to go into great detail, but you should describe enough about these four stages to make the algorithm interesting.

LAMMPS Algorithm:

The LAMMPS(Large Scale Atomic/Molecular Massively Parallel System) algorithm is a classical molecular dynamics code developed at Sandia National Labs, New Mexico. This algorithm models the ensemble of particles in a solid, liquid or gaseous state.

Sequential Algorithm: The initialization step sets up the various parameters for the atom like number of particles, initial velocity, temperature etc. This algorithm is performed for every atoms.
