Maverick (TACC)
Also known as Maverick
Operated by Texas Advanced Computing Center at Texas Advanced Computing Center .
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 Maverick (TACC), and those in USA. 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 | 158.10 TFlop/s | #221 of 245 · bottom 11% | #239 of 332 · bottom 29% |
| Rmax ÷ Rpeak | 63.8 % | #201 of 243 · bottom 18% | #258 of 331 · bottom 23% |
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
TACC's interactive visualization and data-analytics resource, announced 19 Nov 2013 with HP and NVIDIA for deployment in January 2014 to replace Longhorn (longhorn) and complement Stampede (stampede). The announcement describes 132 HP ProLiant SL250s Gen8 compute nodes plus 14 management, login and Lustre-router servers in five racks; each compute node has two 10-core Xeon E5-2680 v2 CPUs, one NVIDIA Tesla K40, 256 GB of DDR3-1866 memory and Mellanox FDR InfiniBand, attached to the 20 PB Stockyard global file system. The TOP500 entry (Jun 2014 rank 397, Nov 2014 rank 474) lists 4,620 cores, Rmax 158.1 TF and Rpeak 247.9 TF and points to TACC's Maverick user guide. The announcement gives January 2014 as the planned deployment month and no later page confirmed the production date, so only the year is recorded.

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.
