Question

Manager-Worker Framework. For this question, we will be writing some pseudocode for the main function, manager function, and worker function following the manager-worker framework for μltiprocessing to perform matrix-vector μltiplication. For a review of the topics relevant to this question, check out Lecture 28: Process-level programming.

a) Main function -> Matrix-vector μltiplication -> Worker function
b) Main function -> Worker function -> Matrix-vector μltiplication
c) Manager function -> Worker function -> Matrix-vector μltiplication
d) Manager function -> Matrix-vector μltiplication -> Worker function

Answer 1

The correct answer is d) Manager function -> Matrix-vector μltiplication -> Worker function. In the manager-worker framework, the manager function is responsible for task distribution, and the worker function performs the matrix-vector multiplication. This sequence ensures efficient task management and computation.

Step-by-step explanation:

The correct answer to the question is d) Manager function -> Matrix-vector μltiplication -> Worker function.

In the manager-worker framework for multiprocessing, the main function is responsible for creating and managing the worker processes. The manager function handles the distribution of tasks to the worker processes, and the worker function performs the actual matrix-vector multiplication.

By following the sequence of the manager function, matrix-vector μltiplication, and worker function, we ensure that the manager has control over the distribution of tasks and the worker processes perform the desired operation efficiently.
