Time out on initializing CUDA It takes too long to start a CUDA program. I don't know why.

Hello everybody,

In the last release of CUDA, that is CUDA 4.1, my programs work well as they did in the past releases, but something weird is happening: it takes too long to start the CUDA program.

When debugging the code, I’ve seen that the problem occurred when the “cudaMallocArray()” function is called the very first time; It takes aproximately 45 seconds to pass through this function.

Can someone tell me why is this happening?

Thanks in advance.
