CUDA Timeout? Options

[yahastu]

Is there some kind of built in timeout period in CUDA that prevents you from calling long-running kernels?

I've written a function that does a large amount of processing in a loop. I compiled the function with both __device__ and __host__ qualifiers, so that I can test it from the cuda kernel as well as on the cpu (the only difference is that I pass a ptr to device memory vs a pointer to host memory). I've tested the function and it works properly, but if I increase the number of processing iterations too high, on the device version the screen goes black and the kernel fails with unknown error.
