SWARM (Wuhan University)
Also known as SWARM
Operated by Wuhan University .
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 SWARM (Wuhan University), and those in China. 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 | 1.40 PFlop/s | #190 of 230 · bottom 18% | #15 of 27 · bottom 47% |
| Rmax ÷ Rpeak | 45.6 % | #213 of 224 · bottom 6% | #26 of 27 · bottom 5% |
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
GPU cluster of the Wuhan University supercomputing centre. TOP500 lists SWARM as Supermicro/Dell EMC C4130/1028GQ servers with Xeon E5-2640v4 10-core 2.4 GHz, Intel Omni-Path 100G and NVIDIA Tesla V100 SXM2 under CentOS, installed 2019, with 32,640 cores, Rmax 1.40 and Rpeak 3.07 PFlop/s and no power figure; it ranked 297th on its first list in June 2019 and 479th on its last, November 2020. The centre's resources page (in Chinese) lists a gpu partition of 125 Supermicro/Dell GPU servers, each with two Xeon E5-2640 v4 (20 cores) and four Tesla V100 16 GB (500 GPUs) on 100G Omni-Path, alongside Omni-Path CPU partitions (30 Lenovo SD530 and 28 Supermicro H240 nodes with Xeon Gold 6248 and 6248R, and 168 Xeon Phi 7250 KNL nodes) and several InfiniBand CPU partitions. The page does not use the name SWARM, gives no performance figure and is undated, so the match between the TOP500 entry and the 125-node partition rests on identical CPU, GPU and fabric; the tier is reported. The operator is the university's supercomputing centre; no street address or in-service date is stated, so the site is left blank.
