Module launch_attr 

Extended launch attributes + cudaLaunchKernelEx (cluster launches, programmatic stream serialization, preferred shmem carveout).

Modern launches go through LaunchExBuilder:

unsafe {
    LaunchExBuilder::new(&stream, (32, 1, 1), (256, 1, 1))
        .cluster_dim((2, 1, 1))
        .cooperative(true)
        .launch(kernel, &mut args)
        .unwrap();
}
