Issues addressed and main goals of research: Carrying out paramount advanced research in computational mathematics and physics, directed to the creation of new mathematical methods,
algorithms, and software for the numerical or symbolicnumerical solution of topics arising in experimental and theoretical physics studies.
This subject area includes a wide spectrum of investigations approved for completion in JINR within the seven year period 2017–2023 in high
energy physics, nuclear physics, physics of condensed matter and of nanostructures, biophysics, information technologies, the solution of
which is inseparable from the use of computing. Such subject matters of the outmost importance in JINR are the NICA project, the neutrino
program, the superheavy and exotic nuclei physics, the neutron based investigations. The needed numerical or symbolicnumerical computing
will be done on the Multifunctional Information and Computing Complex (MICC), primarily the HybriLIT heterogeneous computing platform which
involves the training and test cluster HybriLIT and the "Govorun" supercomputer and the emerging Big Data distributed infrastructure. The
research teams include both experienced scientists with outstanding scientific achievements and enthusiastic young scientists and engineers.
The requested financing will cover salaries, participations in scientific conferences, scientific visits and the acquisition of a minimal
number of personal computers and licenses, within the approved resources for LITJINR. A distinctive feature of this research is the close
cooperation of the Laboratory of Information Technologies (LIT) with research groups from all JINR laboratories and Member State
institutions.
