Lattice Study of QCD Properties at the “Govorun” Supercomputer

Abstract

This report is devoted to Lattice QCD simulations carried out at the “Govorun” supercomputer. The basics of Lattice QCD methodology, the main Lattice QCD algorithms and the most numerically demanding routines are reviewed. We then present details of our multiGPU code implementation and the specifics of its application on the “Govorun” architecture. We show that implementation of very efficient and scalable code is possible and present scalability tests. We finally relate our program with the goals of the NICA project and review the main physical scenarios that are to be studied numerically.
