Conte

Also known as Purdue Conte community cluster

Operated by Purdue University at Purdue RCAC (West Lafayette) .

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: 1092 of 1153 systems have a readable citation that names them, and 40 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: 976.76 TFlop/s
Rpeak: 1.34 PFlop/s
Rmax ÷ Rpeak: 72.8%
Cores: 77,520
Power: 510 kW
Per watt: 1.9 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

Purdue's flagship community cluster, built with HP and Intel as 580 ProLiant SL250 Gen8 servers each carrying two Xeon E5-2670 8-core CPUs and two Xeon Phi 5110P coprocessors, 34th on the November 2013 TOP500 (28th in June 2013, the highest campus system). TOP500 lists 77,520 cores on InfiniBand FDR at 976.76 TFlop/s Rmax, 1.341 PFlop/s Rpeak and 510 kW, on every list from June 2013 to November 2018. Purdue's RCAC page independently confirms the HP and Intel collaboration, dual 8-core Xeon E5 CPUs and two 60-core Xeon Phi per node, FDR10 InfiniBand and a service period from 30 July 2013 to 1 August 2018. TOP500 is the only source for Rmax, Rpeak and power, so the tier is reported.

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
top500.org	names system and part	Intel Xeon E5-2670, Mellanox InfiniBand FDR
rcac.purdue.edu	names system and part	Intel Xeon E5-2670, Mellanox InfiniBand FDR
