Jean Zay V100

Also known as Jean Zay (2019); Jean Zay HPE SGI 8600

Operated by GENCI at IDRIS .

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: 4.48 PFlop/s
Rpeak: 7.35 PFlop/s
Rmax ÷ Rpeak: 61.0%

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

The original Jean Zay at CNRS IDRIS, procured by GENCI as an AI-capable convergence machine: an HPE SGI 8600 with 1,528 CPU nodes and 261 GPU nodes (four Tesla V100 each), dual Xeon Gold 6248 per node, quad-rail Intel Omni-Path at 400 Gb/s and a 1 PB DDN Spectrum Scale flash tier. TOP500 lists 93,960 cores, Rmax 4.48 and Rpeak 7.35 PFlop/s, debuting 42nd in June 2019; it is a separate row from the later Jean Zay H100 extension.

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.
