In recent years with the advent of programming techniques, parallel programming consumes less execution time as compared to sequential. The odd-even merge sort algorithm was developed by K.E. Batcher. It takes two sorted array and merge them into a single sorted array. In this paper, the authors have implemented this algorithm in three different modules and compared the performance of sequential with parallel. Parallelism is achieved by using #pragma parallel in openmp, using message passing in MPI and by using threads in concurrent java.
