   Thanks @rahul003 for looking into this. This is used for a specific purpose --- running Signum over multiple GPU (and multiple machines) and illustrating the communication savings of this algorithm.  The convergence is guaranteed because it is not an approximation to other algorithms, it is the exact algorithm that we analyzed theoretically.
