Genkai Supercomputer System (Research Institute for Information Technology)
Kyushu University's research computing service, operated by the Research Institute for Information Technology (RIIT) around the Genkai supercomputer. Three machine-facing portals run on the university's own hpc.kyushu-u.ac.jp domain and all answered HTTP 200 on 2026-09-01 — a user application portal, a reservation portal and an Open OnDemand instance — but every one of them is a login wall, with access granted through an application and fee process rather than by issuing API credentials. No public API, no token format and no scope list is published. Recorded as an institution-operated surface with an honest note that it is auth_required, not as a callable API. RIIT also maintains the associated open-source work in public: the WHEEL HPC workflow system and CBrick, in the RIIT-KyushuUniv GitHub organization.
