C# OpenCL bindings ready for testing

Hi,

I have download the AMD Stream SDK at : http://developer.amd.com/gpu/ATIStreamSDKBetaProgram/Pages/default.aspx#...

I have download this one : "ati-opencl-beta-driver-v2.0-beta4-xp.zip (109MB)"

But I can't find any OpenCL dll !!!! Even during installation I can't find any option regarding OpenCL :-(

After adding <dllmap os="osx" dll="opencl.dll" target="/System/Library/Frameworks/OpenCL.framework/OpenCL"/> to OpenTK.dll.config the VectorAdd Sample seems to work correctly on my Snow Leopard system. It outputs correct sums of random integers.

Hello,

My system is an AMD Phenom2 X4 940 with 3 * 4870 1GB (they are in crossfireX) on Vista x64, i am running the recently released 9.12 hotfix drivers and i have installed the ati-stream-sdk-v2.0-beta4-vista-win7-64.exe (59.3MB).
I am using VSExpress C# 2008 with the OpenTK-0.9.9-3 and running the VectorAdd from trunk I am seeing the following error (i added additional Error checks after each setting of error):

Launching sample: "Vector Addition"
 
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Exception: InvalidKernelName

Pointing at this :

            CL.BuildProgram(hProgram, 0, (IntPtr[])null, null, IntPtr.Zero, IntPtr.Zero);
 
            // create kernel
            cl_kernel hKernel = CL.CreateKernel(hProgram, "vectorAdd", out error);
            if (error != ErrorCode.Success)
                throw new Exception(error.ToString());
 
            // allocate host  vectors

I see your comment on the Invalid Kernel Name exception above but that was back in late October and i was hoping this was addressed by these latest drivers. Is there anything i should check on my end to see if something is not setup properly?

A friend of mine suggested I put a line here, given the amount of people (inluding him) ending up reading this thread and never finding the oo wrapper mentioned above. So here goes:

Cloo, the .NET, object oriented OpenCL API wrapper, is finally available and can be downloaded from its sourceforge pages.

What is the OP?

Edit: Original Post, got it.
