The 4 Exaflops AI Training system composed of the standard air cooled 32 racks is based on Tachyum Prodigy Universal Processor chip. The single rack supercomputer based on Tachyum reference design will be installed in 2021 at Slovak Academy of Science (SAV) in Bratislava, Slovak Republic. In addition, reference design for the customers will be available at Tachyum locations in Bratislava, Slovakia, and Santa Clara, California, USA. All hardware, software and switch designs will be open sourced allowing end users to build low-cost scalable open systems dramatically reducing cost of acquisition and operation. We would like to present Tachyum universal processor architecture, performance, reference design motherboard, chassis, rack, switches, management software and system software provided by Tachyum.
