All this information should now be passed to the kernel call, see here: http://documen.tician.de/pycuda/driver.html#pycuda.driver.Function.__call__ CUDA (as of 4.0) has deprecated the stateful launch interface (i.e. "set this, set that, go"). For now, PyCUDA still uses stateful launches under the hood, but I've deprecated stateful launches in PyCUDA's user-facing interface as well. That way, when CUDA does remove stateful launches, I'll be in a better position to also remove the stateful interface in PyCUDA and switch to the stateless one at the same time. HTH, Andreas
