Assignment 1 in High Performance Computing (Parallel Processing)

• Using MPI_SEND & MPI_RECV ONLY.
• Running the C code on Ubuntu terminal on virtual box
• Must install MPI first

Problem 1:

Develop a parallel program that outputs max number in a given array.

-> Note:
Size of array may not be divisible by number of processes. So, this case must be handeled

Example where array size is divisible by number of processes

Problem 2 (Matrix Multiplication)

• Write a matrix multiplication program, Matrices’ dimensions and values are taken as an input.
• Take input from console and from file.
• Must use dynamic allocation.
