NASA has nearly completed what will be the world’s largest high-resolution display, dubbed Hyperwall-II, according to Rupak Biswas, chief of advanced supercomputing at the NASA Ames Research Center. The display should be operational within the month, Biswas said. Biswas spoke yesterday at the High Performance Computer and Communications Conference, held in Newport, R.I., this week. The Hyperwall-II will be made of 128 LCD monitors, arranged in an 8-by-16 matrix. Collectively, they will generate 245 million pixels, making it, Biswas said, the world’s largest screen. At least, it will be the largest display for unclassified material.
