CRIEPI HPE Cray XD225v
Operated by CRIEPI .
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 1581 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.

How it compares
Ranked against the other machines in this dataset that report the same figure: those that first came into service within two years of CRIEPI HPE Cray XD225v, and those in Japan. Computed from our tables; a metric is ranked only when at least eight peers report it.
| Metric | Value | Against its era | Against its country |
|---|---|---|---|
| Rmax | 2.37 PFlop/s | #225 of 234 · bottom 5% | #53 of 131 · top 40% |
| Rmax ÷ Rpeak | 91.5 % | #15 of 231 · top 6% | #14 of 130 · top 10% |
Every metric is ranked largest-first, so a high power-draw rank means a big power draw, not a good one. Rmax ÷ Rpeak uses HPL-measured results only. Rankings move as machines are added; they describe this dataset, not the world.
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
HPE Cray XD225v / ProLiant DL380 Gen10 cluster of the Central Research Institute of Electric Power Industry, installed 2024 and entered at rank 466 on the November 2024 TOP500 with 57,408 cores of AMD EPYC 9654 96-core processors, HDR200 InfiniBand, RHEL and AOCC/AOCL/OpenMPI 4.1.6, 2.37 PFlop/s Rmax and 2.59 PFlop/s Rpeak. Rmax is about 92% of Rpeak. TOP500 lists no power figure and no later appearance was found, so status_as_of stays at November 2024. It succeeds CRIEPI's 2012 SGI ICE X (criepi-sgi-ice-x); no CRIEPI page describing the machine's research role was fetched.
