Questions tagged [cudafy.net]

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.
