Kraken-Fregata
Also known as TASK Kraken Fregata partition
Operated by CI TASK at CI TASK Data Centre (Gdansk) .
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.

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 Fregata partition of Kraken at the Centre of Informatics Tricity Academic Supercomputer and networK (CI TASK) of Gdansk University of Technology, installed in 2024. TOP500 lists an HPE Cray XD665 system with AMD EPYC 9334 32-core 2.7 GHz CPUs, NVIDIA H100 94 GB SXM5 GPUs and InfiniBand NDR200 under Rocky Linux: 21,904 cores, Rmax 5.98 PFlop/s, Rpeak 10.02 PFlop/s. TASK describes 80 CPU nodes (HPE Cray XD220v, 56-core Xeon Platinum 2.0 GHz, 512 GB) and 37 GPU nodes (HPE Cray XD665, EPYC 9334, four H100-94 SXM5 each, 768 GB), an InfiniBand NDR200 fat tree and 10.6 PFLOPS of computational power. TOP500 ranks: 154th (June 2024), 185th (November 2024), 217th (June 2025), 248th (November 2025) and 272nd (June 2026).

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 |
|---|---|---|
| task.gda.pl | names system and part | AMD EPYC 9004 (Genoa), NVIDIA H100 SXM5 94GB, NVIDIA InfiniBand NDR (Quantum-2) |
