Mathematical modeling and supercomputer technologies (MMST'2024) Within the International Congress Russian Supercomputing Days Lobachevsky State University of Nizhny Novgorod will hold the Conference and School "Mathematical modeling and supercomputer technologies". The Conference (November 18-19) and School (November 20-21) will further promote the synergy between two priority areas of science and technology - mathematical modeling and supercomputer technologies.The topics of the Conference and School cover a wide range of problems of mathematical modeling of complex processes and numerical methods of research, as well as new methods of supercomputing to solve actual problems in various fields of science, industry, business, and education. The Conference program also features lectures by guest experts, reports by famous scientists and engineers, and presentations by young researchers. The School will include seminars and workshops on the application of state-of-the-art tools and technologies. In general, the Conference and School will provide excellent interaction and networking opportunities for famous scientists and specialists and young researchers who are just beginning their scientific careers.The Conference and School are held under the auspices of the Supercomputer Consortium of Russian Universities. The Conference is organized by the Mathematical Center "Mathematics of Future Technologies" and Volga Research and Educational Center of Supercomputer Technologies of the Lobachevsky State University of Nizhny Novgorod.
