NVidia has just announced the new CUDA 2.2 beta, with several new features. Of particular note is the new debugger for linux, similar to gdb, that allows you to debug kernels as they run on the GPU. Some other features:
- Improved OpenGL interop performance
- Texture from pitch linear memory
- Zero-copy support for direct access to system memory
- Pinned shared system memory allows compute kernels to share system memory
- Asynchronous memcopy on Vista
