The 5th Russian Supercomputing Days Conference (RuSCDays’19) was held Sep-tember 23-24, 2019, in Moscow, Russia. It was was dedicated to the 85th anniversary of academician V.V. Voevodin, the outstanding Russian mathematician who made a valuable contribution to the parallel computing theory and supercomputing technologies. The conference was organized by the Supercomputing Consortium of Russian Universities and the Russian Academy of Sciences. The conference organization coordinator was Moscow State University Research Computing Center. The conference was supported by the Russian Foundation for Basic Research and our respected platinum educational partner (IBM), platinum sponsors (NVIDIA, T-Platforms, Lenovo), gold sponsors (Mellanox, Xilinx, AMD, RSC, Intel, Dell), and silver sponsors (NEC, EAS, DDN). The conference was organized in a partnership with the ISC High Performance conference series. The conference series was born in 2015 as a union of several supercomputing event series in Russia and quickly became one of the most notable Russian supercomputing international meetings. The conference caters to the interests of a wide range of representatives from science, industry, business, education, government, and students – anyone connected to the development or the use of supercomputing technologies. The conference topics cover all aspects of supercomputing technologies: software and hardware design, solving large tasks, application of supercomputing technologies in industry, exaflops-scale computing issues, supercomputing co-design technologies, supercomputing education, and others. All papers submitted to the conference were reviewed by three referees in the first review round. The papers were evaluated according to their relevance to the confer-ence topics, scientific contribution, presentation, approbation, and related works de-scription. After notification of conditional acceptance, the second review round was arranged aimed at the final polishing of papers and also at the evaluating authors’ work based on the referees’ comments. After the conference, the 60 best papers were carefully selected to be included in this volume. The proceedings editors would like to thank all the conference committees mem-bers, especially the Organizing and Program Committee members as well as the refer-ees and reviewers for their contributions. We also thank Springer for producing these high-quality proceedings of RuSCDays’19.
