CUDAfy.NET allows easy development of high performance GPGPU applications completely from the Microsoft .NET framework. It's developed in C#.

Modern graphics cards provide the potential of massive speed increase over CPUs for non-graphics related intensive numeric operations. Many large data set operations such as matrices can see a 100x or more speed up.

CUDAfy allows .NET developers to easily create complex applications that split processing cleanly between host and GPU.

Copy unmanaged System.IntPtr byte vector into GPU row of 2D device byte array

I am using C# and CUDAfy.net (yes, this problem is easier in straight C with pointers, but I have my reasons for using this approach given the larger system). I have a video frame grabber card that is collecting byte[1024 x 1024] image data at 30…
