First release of Campy.NET

The first release build of Campy.NET, v0.01.0000, has been uploaded to To install, download the file, unzip, then execute setup.exe. Campy only works on Windows 8 or 10, and you will need to install Visual Studio Express for Windows Desktop. (Note, VS Professional or Ultimate will also work.) You won’t need to set the CAMPYNETROOT environmental variable mentioned previously, nor download ILSpy or Uncrustify, since these are now installed by the setup program. This release is built with debugging.

To run the code, create a small “Hello World” program, e.g.:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Campy;
using Campy.Types;

namespace ConsoleApplication10
    class Program
        static void Main(string[] args)
            int size = 10;
            int[] data = new int[size];
            for (int i = 0; i < size; ++i) data[i] = 2 * i;
            Extent e = new Extent(size);
            Array_View<int> d = new Array_View<int>(ref data);
            AMP.Parallel_For_Each(d.Extent, (Index idx) =>
                int j = idx[0];
                d[j] = size - j;
            for (int i = 0; i < size; ++i)

Then, in the Solution Explorer, add references to all the DLLs in the Campy.NET installation directory. Finally, build and run the program. Please note: Campy compiles on the fly as the program executes. If you previously built and ran your program, then make changes, Campy will need to rebuild the GPU code. Your program will stop, and prompt you to restart your program in order for Campy to finish rebuilding the GPU code.

Any questions or problems, let me know!

Next, I will be working on enhancing control flow analysis so that function calls of any form will be converted into GPU code. The goal is for programmers to have no need to annotate GPU code using attributes or modifiers. The compiler should be able to do that.
