Efficient parallel prefix algorithms on fully connected message-passing computers

The multi-mesh of trees (MMT) is an efficient interconnection network, which is a hybrid product of multimesh and mesh of trees networks. Several parallel algorithms have been efficiently mapped on this architecture for various problems including root finding, langrage interpolation, matrix multiplication and parallel sorting. In this paper, we propose a parallel algorithm for prefix computation for N = n 4 data on an N-processor multi-mesh of trees which takes 3.75 log N + 6 time for N data points. This can be compared with parallel prefix on the similar architecture, i.e., multi-mesh (MM) which requires 13N 1/4 + log N -1 time.
