Blasting through lattice calculations using CUDA

Understand

Modern graphics hardware is designed for highly parallel numerical tasks and provides significant cost and performance benefits.

• Graphics hardware vendors are now making available development tools to support general purpose high performance computing.
• Nvidia's CUDA platform, in particular, offers direct access to graphics hardware through a programming language similar to C.
• Using the CUDA platform we have implemented a Wilson-Dirac operator which runs at an effective 68 Gflops on the Tesla C870.
