Access violations when using CUDA3.0 with VC++2008

[y09]

Hi everyone,

I’m using VC++2008 and CUDA3.0. I can compile and run the SDK stuff just fine, but now I have created a small application that computes some stuff which has both a CPU and a GPU computation option. It compiles without errors or warnings. Whenever I run it though, I get the following access violations (regardless of whether I’m running it as Administrator or as a normal user). These happen before the program even does anything (I set a breakpoint in the first line of main(), but the violation happens while loading libraries, it seems).

I really don’t know why this happens. When I take out the GPU stuff (i.e. when I remove the GPU code and don’t link cudart into the project) everything is fine and works as expected. I have compared my build configuration with the ones that the SDK projects have and the only thing that’s different is that I’m using CLR (Common Language Runtime) since I’m using Windows Forms (and hence .NET), but that shouldn’t hurt, right?

Any help/ideas are appreciated a lot.

Usually an access violation is triggered when you are trying to read memory where you are not supposed to do so. So in order to find the problem, I suggest that you comment all the CUDA code out, but keep the #include files, and then try adding the CUDA code line by line. See if you can find the line that it is causing the problem.

Beyond the acces violation, to solve probleme with Heap Line 1511 the solution for me was to change Application setting from WindowsForms Application to Console under Liner->System->SubSystem
