Version HistoryVersion 1.0: GPUSort1.0
Requires a programmable NVIDIA Graphics Card (NVIDIA GeForceFX series, GeForce 6 series, and GeForce 7 series), latest NVIDIA drivers (7772 or higher), and GLUT libraries .
Note: We will support ATI GPUs in future releases. The current NVIDIA linux drivers (7664) are not fully optimized and have some performance overhead. Performance will also vary with the GPU used, and for reasonable performance, we recommend a PC with AGP8X or PCI-Express NVIDIA GeForce 6800 GT or faster cards. Our future releases will also include stencil optimizations for better performance. Performance is also higher for 16-bit floats in comparison to 32-bit floats.
Version 2.0: GPUSort2.0
Uses better memory representations and cache optimizations to achieve higher performance ~ 1.5x faster than version 1.0 on most cards. For 7900GTX GPU, use a TILE_SIZE of 128 in GPUSort.cpp. This version only performs key-pointer sorts. Requires a programmable NVIDIA Graphics Card (NVIDIA GeForce 6 series, and GeForce 7 series), latest NVIDIA drivers (7772 or higher), and GLUT libraries .
Alexander Gress indicated that the following two initialization lines in the init function (GPUSort.cpp) are missing in the latest version (GPUSort2.0)
This issue is fixed on Oct 26, 2006.
