 * Description: an implementation of Iallgather using recursive doubling algorithm
 * Limitation: power-of-two number of processes only
 * Time: O(log(comm_size))
 * Schedule length (rounds): O(log(comm_size))
 * Memory: no additional memory requirements beyond user-supplied buffers.
 *
 * Example on 4 nodes:
 *   Initialization: everyone has its own buffer at location rank in rbuf
 *    #     0      1      2      3
 *         [0]    [ ]    [ ]    [ ]

 *         [ ]    [ ]    [2]    [ ]
 *         [ ]    [ ]    [ ]    [3]
 *   Step 0: exchange data with (rank ^ 2^0)
 *    #     0      1      2      3
 *         [0]    [0]    [ ]    [ ]

 *         [ ]    [ ]    [2]    [2]

 *   Step 1: exchange data with (rank ^ 2^1) (if you can)
 *    #     0      1      2      3
