8K? That’s cute. TACC’s Stallion pushes 597 million pixels • The Register

In the event you thought 8K was excessive res, then this supercomputer lab’s newly revamped Stallion tiled show system invitations you to suppose larger — a lot larger.
The huge show claims a decision of 46,080 x 12,960 pixels. Put one other manner, that works out to simply shy of 600 megapixels, or in TV advertising and marketing converse 46K.
Nevertheless, this is not some stadium Jumbotron or theater projection. As you may count on, Stallion is not one panel, however as an alternative a set of 18 Samsung 8K QLED TV, with every 65-inch display screen organized in a 6×3 grid measuring roughly 28-feet broad by 8-feet tall.

The aim of Stallion, based mostly on the Texas Superior Computing Heart (TACC), is the visualization of enormous scientific datasets. In a current write-up Jo Wozniak, a visualization specialist engaged on Stallion, defined that the upper decision and larger brightness will permit boffins to select particulars that in any other case would have been missed with out the bigger scale.
As an example, one of many first purposes of the up to date array was by the Cosmic Evolution Early Launch Science Survey (CEERS), which used Stallion to visualise knowledge collected by the James Webb House Telescope. One other utility is for high-resolution rendering of fashions.

“Stallion is right for showcasing Digital Angkor, our absolutely realized creation of the Cambodian metropolis of Angkor round 1300 CE,” UT Austin Historical past Professor Adam Clulow defined.

In keeping with Paul Navrátil, TACC’s director of strategic applied sciences, the choice to make use of 8K panels was primarily a future-proofing measure. The upgrades come “originally of a know-how curve in 8K televisions, which is able to permit us to take care of a strong technological foundation.”
It most likely does not damage that 8K TVs have gotten significantly cheaper lately. A fast search of BestBuy reveals fashions as little as $1,299, although it is not clear which mannequin of Samsung tv TACC is utilizing in Stallion.

In some methods the newest iteration of Stallion is definitely simpler than prior to now. The primary technology of the array used 80, 30-inch displays in a 16 broad by 5 broad configuration. However regardless of utilizing extra displays, it provided much less decision — 328 megapixels versus 597 — and was hardwired in such a manner that meant it may solely be used as a single monolithic show.
By comparability, the up to date array is split into six individually addressable columns, three displays tall. These will be mixed right into a single massive panel, or damaged out into smaller clusters, permitting for a number of knowledge sources to be displayed concurrently.

Whereas the 18 high-res shows will be the star of the present, operating knowledge visualizations at these resolutions requires a substantial quantity of computational horsepower.
Stallion is powered by a cluster of 36, hexacore Sandy Bridge CPUs every with an identical Nvidia Quadro K5000 GPU for a complete 232 processor cores, 19TB of disk storage, 1.28TB of reminiscence, and 74 gigabytes of GPU reminiscence.
Visualized knowledge rendered by the cluster are then distributed throughout the shows utilizing software program developed by TACC’s visualization staff known as DisplayCluster and MostPixelsEver: Cluster Version. ®
