There was an interesting question on Gamedev.net today asking about whether there is an API in C# for querying information about the GPUs installed. Apparently, GPU-Z uses the CUDA API to get information about an NVIDIA GPU, and GPUPerfAPI for the AMD GPU. However, a good alternative to those APIs is OpenCL, a platform independent framework to …

Lately I have been converting some GPGPU algorithms from CUDA into C# and the Task Parallel Library, e.g., tiled reduction. However, I noticed a significant problem in the efficiency of the System.Threading.Barrier class for task synchronization. This problem was also noted by Andrea Esuli here, who proposed an incomplete solution. As stated in the documentation, “[Barrier] enables multiple tasks …
