Operated by SciNet .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

The read
SciNet's Tightly Coupled System, a cluster of fat IBM Power 575 nodes with 4.7 GHz POWER6 processors (32 cores and 64 SMT threads, 128 GB RAM per node, two nodes with 256 GB, running AIX) on InfiniBand, reserved for jobs needing large memory and low latency. SciNet gives installation as January 2009 and decommissioning as 29 September 2017 and an approximate 3,000 cores; TOP500 lists 3,328 cores, Rmax 48.93 TF, Rpeak 62.57 TF and 531 kW, an installation year of 2008, and entries from Jun 2009 (rank 80) to Jun 2011 (rank 325), with rank 115 in Jun 2010. The 2008 versus 2009 start differs between the two sources. Sibling of scinet-gpc, which handled the throughput workload.

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 |
|---|---|---|
| scinethpc.ca | names system only | - |
| top500.org | does not name this system | - |
