That’s .25 billion pixels people. We’ve got a (smaller) powerwall at my work, and it gets pretty hot. I imagine you’ll have to wear a heat suit to use this thing.
Here is the lede
Developed by scientists and engineers in the NASA Advanced Supercomputing (NAS) Division at Ames, the 128-screen hyperwall-2, capable of rendering one quarter billion pixel graphics, is the world’s highest resolution scientific visualization and data exploration environment.
And some stats
Designed and developed by the NAS visualization team in partnership with Colfax International, Sunnyvale, Calif., the system is powered by 128 graphics processing units and 1,024 processor cores, with 74 teraflops (one teraflop equals one trillion floating point operations per second) of peak processing power and a data storage capacity of 475 terabytes (one terabyte equals one trillion bytes).
