    Return the absolute position of the current thread in the entire grid of
    blocks.  *ndim* should correspond to the number of dimensions declared when
    instantiating the kernel. If *ndim* is 1, a single integer is returned.
    If *ndim* is 2 or 3, a tuple of the given number of integers is returned.

    Computation of the first integer is as follows::

        cuda.threadIdx.x + cuda.blockIdx.x * cuda.blockDim.x

    and is similar for the other two indices, but using the ``y`` and ``z``
    attributes.

    Synchronize all threads in the same thread block.  This function implements
    the same pattern as barriers in traditional multi-threaded programming: this
    function waits until all threads in the block call it, at which point it
    returns control to all its callers.
