cuda.net

I'm trying to write a childish app with CUDA.Net, but I'm out of luck. I've figured out to: using GASS.CUDA; // ... var c = new CUDA(); // c.Launch(myfunc); // ???? how ??? myfunc apparently should be of type GASS.CUDA.Types.CUfunction but I didn't find how to define one. First you need a .cu file with your kernel (function to be executed on a GPU). Let's have a file mykernel.cu : extern "C" __global__ void fooFunction(float4* data) { // there can be some CUDA code ... } This have to be compiled into a .cubin file with the nvcc compiler. In order to let the compiler know of the Visual C++

When writing CUDA applications, you can either work at the driver level or at the runtime level as illustrated on this image (The libraries are CUFFT and CUBLAS for advanced math): (source: tomshw.it ) I assume the tradeoff between the two are increased performance for the low-evel API but at the cost of increased complexity of code. What are the concrete differences and are there any significant things which you cannot do with the high-level API? I am using CUDA.net for interop with C# and it is built as a copy of the driver API. This encourages writing a lot of rather complex code in C#

I'm trying to set my simulation params in constant memory but without luck (CUDA.NET). cudaMemcpyToSymbol function returns cudaErrorInvalidSymbol. The first parameter in cudaMemcpyToSymbol is string... Is it symbol name? actualy I don't understand how it could be resolved. Any help appreciated. //init, load .cubin float[] arr = new float[1]; arr[0] = 0.0f; int size = Marshal.SizeOf(arr[0]) * arr.Length; IntPtr ptr = Marshal.AllocHGlobal(size); Marshal.Copy(arr, 0, ptr, arr.Length); var error = CUDARuntime.cudaMemcpyToSymbol("param", ptr, 4, 0, cudaMemcpyKind.cudaMemcpyHostToDevice); my .cu
