This paper considers 2-dimensional mesh-connected computers with multiple broadcasting (2-MCCMBs). A 2-MCCMB is constructed by augmenting a 2-dimensional mesh-connected computer with broadcasting features in each row and each column. One property of the modified mesh is that rectangular 2-MCCMBs, instead of square ones, are the best form for several algorithms. For the median problem of N numbers, a previous algorithm with time complexity O(N 1 6 ( log N) 2 3 ) was developed on an N 1 2 × N 1 2 2-MCCMB. This paper shows that the time complexity can be reduced to O(N 1 8 log N) if an N 5 8 × N 3 8 rectangular 2-MCCMB is used. Using the above result, we further develop algorithms for two-variable linear programming on an N 5 8 × N 3 8 2-MCCMB, where N is the number of constraints. In addition, to achieve better performance on the N 5 8 × N 3 8 2-MCCMB, we further modify a previous prune-and-search strategy for solving the problem and eventually obtain a parallel algorithm with O(N 1 8 log N) time on an N 5 8 × N 3 8 2-MCCMB. |
