Rocket Cluster
Also known as UT Rocket
Operated by University of Tartu at University of Tartu HPC Centre .
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.
| Role | Part | Supplier at build | Quantity | Confidence | Source |
|---|---|---|---|---|---|
| Accelerator | - 2 machines with 4x NVIDIA H200 NVL 141GB PCIe each (Firefly nodes), joined by 200 Gbps InfiniBand | NVIDIA | 8 reported | Reported | hpc.ut.eehpc.ut.ee |
| Accelerator | NVIDIA Tesla V100 Accelerators CUDA (Volta GV100) · 5,120C · 1.53 GHz · 12 nm · 300 W 44 NVIDIA Tesla V100 GPUs (16-32 GB) on Falcon nodes 1-6 | NVIDIA | 44 reported | Reported | hpc.ut.ee |

The read
The University of Tartu HPC Center's flagship heterogeneous cluster, the main academic HPC and AI resource in Estonia, open to third parties via the national ETAIS system. The centre's own Rocket page lists 50 compute nodes (40 AMD EPYC CPU nodes, 10 GPU nodes) and headline totals of almost 12,000 cores, just over 5 TB of memory and 64 GPUs on 100-200 Gbps InfiniBand, with two GPFS file systems of 4.7 PB and 5.9 PB. GPU nodes carry NVIDIA V100, A100 and, since August 2025, two 4-GPU H200 NVL 141 GB machines bought for Estonian-language model training, linked by 200 Gbps InfiniBand, alongside eight NVIDIA L40S GPUs in the university's cloud. Both cited pages are published by the operator, so confidence is reported; no LINPACK or peak FLOPS figure is published, so FLOPS and an exact core count are left blank.

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 |
|---|---|---|
| hpc.ut.ee | names system only | - |
| hpc.ut.ee | names system, part and count | NVIDIA Tesla V100, AMD EPYC 7763 (Milan) · counts: 44 |
