CUDPP 1.1.1

April 29th, 2010

The CUDA Data Parallel Primitives Library (CUDPP) is a cross-platform, open-source library of data-parallel algorithm primitives such as parallel prefix-sum (“scan”), parallel sort and parallel reduction. Primitives such as these are important building blocks for a wide variety of data-parallel algorithms, including sorting, stream compaction, and building data structures such as trees and summed-area tables. CUDPP runs on processors that support CUDA.

CUDPP release 1.1.1 is a bugfix release with fixes for scan, segmented scan, stream compaction, and radix sort on the NVIDIA Fermi (sm_20) architecture, including GeForce 400 series and Tesla 20 series GPUs.  It also includes improvements and bugfixes for radix sorts on 64-bit OSes, and fixes for 64-bit builds on MS Windows OSes and Apple OS X 10.6 (Snow Leopard).  Change Log.
