Apocrita
Also known as QMUL Apocrita; Queen Mary HPC
Operated by Queen Mary University of London .
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 | - NVIDIA GPU nodes: 2 ddg (Volta), 2 sbg (Volta), 1 sbg (Ampere) | NVIDIA | - | Reported | docs.hpc.qmul.ac.uk |
| CPU | - Intel nodes: 167 ddy, 52 sdx, 8 smf, 2 srm, 4 vhm and GPU hosts | Intel | - | Reported | docs.hpc.qmul.ac.uk |
| CPU | - AMD ehc nodes, 12 nodes of 384 cores | AMD | - | Reported | docs.hpc.qmul.ac.uk |
The read
Apocrita is the HPC cluster at Queen Mary University of London. The node-overview page tabulates the open-access nodes at 250 nodes, 15,224 cores (hyperthreading disabled) and 163 TB of RAM: 167 ddy and 52 sdx Intel nodes, 12 ehc AMD nodes of 384 cores each, 8 smf, 2 srm and 4 vhm large-memory nodes, and GPU nodes (2 ddg Volta, 1 sbg Ampere, 2 sbg Volta). Some further nodes are restricted by funding source and are outside that total. Operator documentation only, so the tier is reported.

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 |
