SOFTWARE:

A high performance DFT library on GPUs using the modern compute languages on GPUs with performance up to 300 GFLOPS on a single GPU. Library handles non-power-of-two sizes, multi-dimensional transforms and achieves high numerical accuracy on single-precision inputs. Joint work with Brandon Lloyd, Yuri Dotsenko, Burton Smith and John Manferdelli at Microsoft. Research will be presented at ACM/IEEE SuperComputing 2008.

GPUFFTW: High-Performance Power-of-Two FFT Library using Graphics Processors is released publicly on May 26, 2006. The library is highly tuned for GPUs using compute and memory optimizations and is able to achieve over 15 GFLOPS on large 1D FFTs using a NVIDIA 8800 GPU. More than 4000 download requests at the release and the technical paper appeared in ACM SuperComputing 06 (joint work with Scott Larsen, Jim Gray and Dinesh Manocha).

GPUTeraSort (joint work with Jim Gray, Ritesh Kumar and Dinesh Manocha) is a high performance-price solution for handling hundred gigabyte scale databases! CPU-based sort speeds have plateaued during the past decade (see Jim's commentary). GPUTeraSort shows a significant performance benefit achieving 3x more records/sec. GPUTeraSort is the world's fastest reported performance/price sorting system and is the 2006 Indy PennySort winner. Press releases in NYTimes and Wired Magazine

LUGPULIB : A Fast Dense Linear Solver Library on GPUs released publicly in November 2005. Over 1000 download requests were received.

GPUSORT : A High Performance GPU Sorting Library released publicly in July 2005. Over 3500 download requests were received.
