How to read this finding
This counts the GPUs in the Booster’s standard compute nodes, not every processor or login node in the wider system. A GPU inventory is also different from a supercomputer performance ranking such as TOP500.
How many GPUs does Europe’s JUPITER supercomputer have?
By Nathan Benaich (Air Street Capital)Index cutoff · October 1, 2026
The index records 23,536 deployed GH200 GPUs in JUPITER’s Booster module at Jülich. The operator specifies 5,884 compute nodes, each with four Grace-Hopper Superchips, matching that count.
