Question

Write the main function for a manager-worker program that performs matrix-vector multiplication using the MPI framework. Put the following blocks of pseudocode in the correct order:

a. Initialize the MPI program.
b. Determine the size and rank of the current process.
c. Call either the manager or worker function depending on the rank of the current process.
d. Finalize the MPI program.

Answer 1

The main function for a manager-worker program performing matrix-vector multiplication using the MPI framework consists of initializing the program, determining the process size and rank, calling the manager or worker function, and finalizing the program.

Step-by-step explanation:

1. Initialize the MPI program.
2. Determine the size and rank of the current process.
3. Call either the manager or worker function depending on the rank of the current process.
4. Finalize the MPI program.

In a manager-worker program that performs matrix-vector multiplication using the MPI framework, the main function should consist of these steps. First, the MPI program is initialized. Then, the size and rank of the current process are determined. Depending on the rank, either the manager or worker function is called. Finally, the MPI program is finalized.
