A parallel algorithm is presented which merges two sorted lists represented as 2–3 trees of length m and n (m≦ n), respectively, with at most 2m processors within O(log n) time. The consideration for the time complexity includes comparisons, allocation of processors, and construction of an output 2–3 tree. The algorithm is performed without read conflicts.
