High-Performance Computing: Application to Ab-Initio Simulations of X-Ray Absorption Spectra From Nanoparticles
Overview High-Performance Computing (HPC) is associated with the use of high-end computer systems, so-called 'Supercomputers', for solving complicated computational problems. Today HPC infrastructure is a critical resource for research and development as well as for many business applications. The standard tasks, which are addressed by HPC systems, require normally hundreds or even thousands of processor hours to complete. Therefore special approaches, based on dedicated software and hardware components, have to be used. This paper discusses basics of high performance computing on the example of the LAtvian SuperCluster (LASC), installed at the Institute of Solid State Physics of the University of Latvia. The application of LASC to ab-initio simulations of x-ray absorption spectra from nanoparticles is considered as a particular case.
