Just in time before many of NVIDIA's engineers leave for the holidays, the first beta of CUDA 2.1 has been released. The beta for version 2.1 of the Compute Unified Device Architecture
brings a few changes to both the SDK and Toolkit.
The only major change in the CUDA 2.1 Beta Toolkit is improved OpenGL interoperability by only copying shared buffers through the host memory when CUDA and OpenGL are running on different GPUs. The CUDA 2.1 Beta SDK brings smokeParticles for volumetric particle shadows samples and a cutil_inline.h header file.
This beta release isn't particularly interesting and what it also lacks is any support for OpenCL
layered atop CUDA. Though CUDA 3.0 is already being worked on for introduction in 2009.
