Light–matter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes these limitations.
Researchers led by the University of Tsukuba present an improved way to model interactions between matter and light at the atomic scale TSUKUBA, Japan,

Abstract:
Researchers from the HSE International Laboratory for Supercomputer Atomistic Modelling and Multi-scale Analysis, JIHT RAS and MIPT have compared the performance of popular molecular modelling programs on GPU accelerators produced by AMD and Nvidia. In a paper published by the International Journal of High Performance Computing Applications, the scholars ported LAMMPS on the new open-source GPU technology, AMD HIP, for the first time.
Open-source GPU technology for supercomputers: Researchers navigate advantages and disadvantages

The scholars thoroughly analysed the performance of three molecular modelling programs - LAMMPS, Gromacs and OpenMM - on GPU accelerators Nvidia and AMD with comparable peak parameters. For the tests, they used the model of ApoA1 (Apolipoprotein A1) apolipoprotein in blood plasma, the main carrier protein of good cholestero
