This white paper describes how GPGPU technology supports unprecedented processing density in Commercial Off The Shelf (COTS) computing systems. GPGPU technology enables system designers to massive processing power into small spaces. The paper illustrates a very compact VPX configuration with a floating point performance of 766 GFLOPS in less than 0.4 cubic feet. With configuration control and lifecycle management from leading COTS suppliers, these technologies are clearly ready for duty.
