SYSC 4001 Assignment 3 Part 2: Concurrent Processes

• Student 1: Justin Morrison (101302852)
• Student 2: Random Hygaard (101273397)

IMPORTANT

All commits for this repo are under Justin's name, however, Random helped over Discord calls and during the lab, it was just easier to submit on 1 computer.

How to run

Run each part by executing the associated build script with a command line arguement for number of TA processes:

• For Part A run:

bash run_partA.sh <n>

• For Part B run:

bash run_partB.sh <n>

Where n is the number of processes that will be created.

NOTE:

Both parts use the same rubric.txt file located into the top directory. Might want to reset the file if running both back to back.

Report

The report discusisng the design of the program can be found in the file reportPartC.pdf in this repo or submitted in Brightspace.

Example terminal output of running Part B with 4 TA processes
