| Summary: | Molecular dynamics is a method to simulate movements of atoms or particles
in a system. The simulation is computationally complex and the performance
heavily depends with the computer. As such, a high performance computation
system is necessary to achieve the optimal eciency. One of the solutions is by
using parallel computation to speed up the simulation running time. In this
research, we use CUDA API developed by Nvidia, to create a parallel molec-
ular dynamics simulation with the help of Nvidia's own GPUs. The system
used in this simulation is the noble gas particles, i.e. Helium, Neon, Argon,
Krypton, Xenon, and Radon. Interactions between particles is modeled by us-
ing Lennard-Jones potential and the equations of motion which are integrated
with velocity Verlet method. The system is then benchmarked by making com-
parisons of the execution time between the serial, parallel simulation GPU on
CUDA cores, and parallel simulation CPU with OpenMP. The running time
of the parallel simulation is faster than the serial one. |
