            1 // launch.h -- backend-agnostic kernel launch macro.
            2 // The argument list is passed parenthesized, e.g.
            3 //   KERNEL_LAUNCH(interact, dimGrid, dimBlock, 0, (dev_x, dev_vel));
            4 // so commas inside it never split macro arguments, and templated kernels
            5 // like setNSghostNodes<Float3> work as the kernel argument.
