Graphics processing on a graphics supercomputer

A description is given of the Titan Graphics Supercomputer. The primary design philosophy was to have as little redundant hardware as possible and to make as much of the hardware available to compiled application code as possible. This led to a design with multiple parallel processors, each with an integer unit and a vector floating-point unit. The system provides 3D graphics and image processing, using the main processors for most computations. The graphics subsystem consists of only a frame buffer with rasterization (vector and triangle pixel drawing) support. The Titan architecture provides a very good balance of computation and graphics but to make it more competitive in graphics or imaging-intensive applications, a special-purpose accelerator also fits into the architecture.<>
