The Supercomputer Center (SCC) operates a supercomputer system available to all researchers of condensed matter physics in Japan. One can submit a proposal for a User Program to the Supercomputer Steering Committee, and once granted he/she can use the facility with no charge. The supercomputer system consists of two systems: The main system (System B (ohtaka)) and the sub-system (System C (enaga)). In addition to maintaining high performance of the hardware in cooperation with the venders, the SCC also responds to questions and inquiries from users on a daily basis. In 2015, aiming at more efficient usage of the supercomputer systems, we started a new program PASMUS for developing 2 or 3 applications annually based on proposals from the ISSP supercomputer users.

System B (ohtaka) : 1680 CPU nodes (Dell PowerEdge C6525, AMD EPYC 7702 (64 cores)) + 8 FAT nodes (Dell PowerEdge R940, Intel Xeon Platinum 8280 (28 cores) ×2) (total theoretical performance = 6.881 PFLOPS) System C (enaga) : 252 nodes (HPE SGI 8600, Intel Xeon 6148 (20 cores) ×2) (total theoretical performance = 0.77 PFLOPS)
