Function launch_kernel 

pub unsafe fn launch_kernel(
    func: CudaFunction,
    grid: Dim3,
    block: Dim3,
    args: &mut [*mut c_void],
    shared_mem: u32,
    stream: CudaStream,
) -> CudaRtResult<()>

Launch a CUDA kernel.

Mirrors cudaLaunchKernel (with explicit function handle).

Parameters

• func — compiled kernel function (from module_get_function).
• grid — grid dimensions.
• block — block dimensions.
• args — mutable slice of pointers to kernel arguments; each element must point to the actual argument value, as required by cuLaunchKernel.
• shared_mem — dynamic shared memory in bytes.
• stream — CUDA stream on which to enqueue the launch.

Safety

• func must be a valid kernel handle.
• Each args[i] pointer must point to a value whose type matches the kernel’s i-th parameter.
• shared_mem must not exceed the device’s maximum shared memory per block.

Errors

Propagates driver errors.
