As symbolized by the Fugaku computer, massively parallel and exhaustive computation is actively used for solving problems in materials science in recent years. In fact, computer-aided science has been providing answers to many problems ranging from the most fundamental ones, such as critical phenomena in quantum magnets, superconductors, and superfluids, to the ones with direct industrial applications, such as semiconductor devices and electrode chemical reactions in batteries. Due to the recent hardware trends, it is now crucial to develop a method for breaking up our computational task and distribute it to many computing units. In order to solve these problems in an organized way, we, as the major contractor of several national projects such as Fugaku Computer Project and the DxMT project, coordinate the use of the computational resources available to our community, including Fugaku and ISSP supercomputers. In addition, we also operate the web site, MateriApps, which offers easy access to various existing codes in materials science, and in order to develop human resources for the doctoral program, we promote the Advanced Human Resource Development and Industry-Academia Matching Program for Computational Materials Science.
