We present a new optimal deterministic parallel algorithm for merging two sorted arrays A = (a0, a1, ? ? ? , an1-1) and B = (b0, b1, ? ? ? , bn2-1) of integers. The elements of two sorted arrays are drawn from a domain of integers [0, n - 1], where n = Max(n1, n2). The algorithm takes O(log n) time and O(n) space using n/ log n processors on EREW PRAM. Also, the algorithm is stable.
