ISM SGI 8600

Also known as Institute of Statistical Mathematics HPE SGI 8600 (2018)

Operated by Institute of Statistical Mathematics .

Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1263 of 1345 systems have a readable citation that names them, and 56 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

Measured performance

Rmax: 941.28 TFlop/s
Rpeak: 1.33 PFlop/s
Rmax ÷ Rpeak: 70.9%
Cores: 13,824
Power: 268.49 kW
Per watt: 3.5 GF/W

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.

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

HPE SGI 8600 cluster at the Institute of Statistical Mathematics: Intel Xeon Gold 6154 18-core 3 GHz processors, 13,824 cores, EDR InfiniBand and Red Hat Enterprise Linux. TOP500 gives 941.28 TFlop/s Rmax, 1,327.10 TFlop/s Rpeak and 268.49 kW, ranked 462nd in November 2018, its only appearance (https://top500.org/system/179562/). TOP500 is the only source, and the institute's own specification page was not found, so the tier is reported and status is held as of that list.

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.

Every source cited on this page was readable, and none of them mentions this system. They are cited at page granularity, normally because no stable deep link could be found. That is a real weakness in this row and it is why the system carries a confidence tier below verified. See how this check works.
