Also known as TIGRIS
Operated by Rochester Institute of Technology .
Researched with AI assistance, checked by scripts. These rows were researched by AI agents reading public operator, laboratory and vendor sources, appended by scripts and checked by automated validation; no subject-matter expert has reviewed them (how this site is made). A mechanical second-reader pass has since fetched every cited source: 1350 of 1540 systems have a readable citation that names them, and 64 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.

The read
Rochester Institute of Technology's research cluster, launched in summer 2026 as the successor to the university's earlier SPORC cluster. RIT says Tigris delivers three times SPORC's CPU performance and seven times its GPU performance, and that average job waits fell from about 6 hours to about 18 minutes; it was built with Nvidia, Supermicro and Chilldyne using liquid cooling, and RIT Research Computing (executive director Matangi Buch) serves colleges across the university with work in black-hole merger modelling, genomics and fuel-cell materials. RIT reports 302nd on the June 2026 TOP500 (list full for our table, so no list row) and 82nd on the Green500. TOP500 lists a Supermicro ARS-111GL-DNHR-LCC with NVIDIA GH200 (GH Superchip 72C 3 GHz), InfiniBand NDR400, Red Hat Enterprise Linux, 31,296 cores, Rmax 5.08 and Rpeak 9.27 PFlop/s, 132.87 kW and HPCG 59.725 TFlop/s. RIT's article gives no node, GPU or CPU counts and does not say where the machine is housed, so site is blank.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
| Cited source | Result | Found on the page |
|---|---|---|
| rit.edu | names system only | - |
| top500.org | names system and part | NVIDIA InfiniBand NDR (Quantum-2) |
