Campy. is an API for GPGPU programming for C#, and modeled after Microsoft's C++ AMP. Campy uses unattributed, anonymous C# lambda functions for GPU code, providing a solution to the problem of locality of declaration of GPU kernel and caller. In other words, GPU and CPU code can be co-mingled, and there is no tagging of GPU code. The goal will be to use a unified memory model in order to provide automatic synchronization/shared GPU/CPU memory data structures, with an interface similar to the System.Threading.Tasks.Parallel class.
Campy uses LLVM for code generation, currently targeting 64-bit Windows with CUDA Maxwell or new GPUs. There is currently no release as it is still under development.
Campy is under GIT version control in https://github.com/kaby76/campy.
