Question

Write an MPI program that implements the hypercube bitonic sort algorithm. The program should be tested using a sequence of 64 integers

(from 1 to 64, initially not sorted) and 8 processes. The number of elements assigned to each process is 8.

Answer 1

The hypercube bitonic sort algorithm is used to sort elements using a hypercube network topology. Each process performs comparisons and swaps based on its rank and position. To implement it using MPI, you would create a hypercube communication structure and divide the elements evenly among processes.

Step-by-step explanation:

The hypercube bitonic sort algorithm is used to sort elements using a hypercube network topology. In this algorithm, each process performs comparisons and swaps based on its rank and the position of the elements in the hypercube.

To implement the hypercube bitonic sort algorithm using MPI, you would need to create a hypercube communication structure and divide the elements evenly among the processes. Each process would compare and swap its assigned elements based on their ranks and positions in the hypercube. Finally, you would merge the sorted elements to obtain the completely sorted sequence.

For the given scenario of 64 integers and 8 processes with 8 elements each, you can think of the sequence of integers as a 2D grid with 8 row processors and 8 column processors. Each processor would be responsible for sorting its row or column. After sorting each row and column individually, you would merge the sorted rows and columns to obtain the completely sorted sequence.
