GridKa

Also known as Grid Computing Centre Karlsruhe

Operated by Karlsruhe Institute of Technology at KIT Scientific Computing Centre (Karlsruhe) .

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.

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

German WLCG Tier-1 centre for particle and astroparticle physics, hosted by KIT's Scientific Computing Center and delivering resources since October 2002. KIT's page (last changed April 2026) states about 740 kHS06 of CPU power, 82 PB of usable disk and about 218 PB of usable tape, with 200 Gb/s to CERN and 400 Gb/s to the German research network; it supports all four LHC experiments plus Belle II, COMPASS, Pierre Auger, IceCube and, since 2023, XLZD, and holds 15 percent of committed Tier-1 CPU. A November 2021 status report from the same group gives the hardware generation then being installed: 196 dual-socket AMD EPYC 7742 nodes with 570 GB RAM and 7 TB NVMe, about 50,000 logical cores and 550 kHS06 in total, 56 NVIDIA V100 GPUs, and 46.4 PB of online disk with a 71 PB tender under way. Core count is left blank because the 2026 page reports only kHS06. It is a distributed high-throughput farm, not an HPL-ranked machine.
