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)), which started operation in Oct. 2020, and the sub-system (System C (kugui)), which started operation in June 2022. Information about project proposals can be found in the center's web page (https://mdcl.issp.u-tokyo.ac.jp/scc/). 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 a few applications annually based on proposals from the ISSP supercomputer users.

System B (ohtaka): Dell PowerEdge C6525/R940 (1680 CPU nodes of AMD EPYC 7702 (64 cores) and 8 FAT nodes of Intel Xeon Platinum 8280 (28 cores) with total theoretical performance of 6.881 PFLOPS)
System C (kugui): HPE Apollo 2000 Gen10 Plus/HPE Apollo 6500 Gen10 Plus (128 CPU nodes of AMD EPYC 7763 (128 cores) and 8 ACC nodes of AMD EPYC 7763 (64 cores) with total theoretical performance of 0.973 PFLOPS)
