LARGE-SCALE MOLECULAR-DYNAMICS SIMULATION OF 19 BILLION PARTICLES

Large-scale Molecular-dynamics Simulation of 19 Billion Particles

We have performed parallel large-scale molecular-dynamics simulations on the QSCmachine at Los Alamos. The good scalability of the SPaSM code is demonstrated together with its capability of efficient data analysis for enormous system sizes up to 19 000 416 964 particles. Furthermore, we introduce a newly-developed graphics package that renders in a very efficient parallel way a huge number of s...

Large Scale Simulation of Parallel Molecular Dynamics

This paper aims to describe the implementation of TAKAKAW, an efficient parallel application for the simulation of molecular dynamics designed to handle large proteins in biology. The implementation is based on the multi-threading parallel programming environment, called ATHAPASCAN 1 which allows to implement and evaluate easily several load-balancing strategies. Some experiments run on one of ...

Large Scale Molecular Dynamics Simulation of Aqueous NaCl Solutions

The understanding of aqueous solution properties is recognized as being important in many areas of physical chemistry and molecular biophysics. Computer simulation has become an important tool in understanding the structure and dynamics of aqueous electrolyte solutions at the atomic or molecular level. Many works of molecular dynamics (MD) simulations have been carried out to investigate hydrat...

Removal of Heavy Metal Particles by LTJ, ANA, SVR, BEC and MER zeolites particles: A Molecular Dynamics Simulation Study

In present study, molecular dynamics simulation of Cadmium (II), Lead (II) and Copper (II) removal from aqueous electrolyte solutions using the ion-exchange process with the zeolite particles was done. The results showed that, most of the particles had the highest affinity of ion exchanging with Lead (II) and the lowest affinity with Copper (II). The calculated mean ion-exchange ratios showed t...
