Free tier	Large allocations from 125,000 to 500,000 SUs on Horizon and up to 50,000 SUs on Vista for six months, with submissions opening 15 April 2026 and rolling review from 15 May 2026, on a system carrying 4,750 Vera CPU nodes and 2,000 Grace-Blackwell GPU nodes. unit none; metered on wall-clock; merit-reviewed allocation

Composes with	The non-US route is as a collaborator with substantive intellectual participation by the US partner, which is the same shape as the ACCESS escape hatch and equally dependent on a US collaborator existing.
Reliability	no reliability event recorded
Notes	The largest US number found after INCITE: 500,000 SUs on the newest NSF leadership system. SUs are a site-defined service unit, not GPU-hours or core-hours, so converting them would be invention. Recorded as a refutation of the idea that the newest NSF hardware is open to anyone: it requires a US base and existing peer-reviewed funding.
