[MPI] Solution 1 : Hello World

This material is part of the course Practical Introduction to Parallel Programming and meant for educational purposes only.


Task

Implement a small MPI program that prints the total number of processes and the rank of the current process.


Question 1: Hello World
Question 2: Number of MPI processes

Specify the number of MPI processes (1-64) that should be used for running your program (mpirun -np <nproc>)

Question 3: Command Line Argument

Specify the command line arguments that should be passed to your program when it is run. Arguments must be given in quotes and separated by commas. Leave this filed empty if you do not want to specify command line arguments.

Example: "1","int","arg=2" is interpreted as three arguments 1, int, and arg=2.
