REX Computing is developing the future of massively parallel and high density computing systems that target the high performance computing (HPC) and server marketplaces. REX has developed a new highly scalable processor and system level compute node architecture with a focus on providing superior energy efficiency (performance per watt) in comparison to solutions provided by both market incumbents and competing startups alike. Our architecture relies on densely packed, custom processor chips and is designed to enable a large amount of computing performance while offering extreme power efficiency, scalability, and practical programmability.
