Process Manager (psmgmt)

Overview

The Process Manager (psmgmt) is designed to simulate an operating system's process scheduling and inter-process communication using shared memory. This simulation includes a "simulated system clock" and a process table consisting of Process Control Blocks (PCBs) for each process. The latest update introduces advanced resource management and deadlock detection mechanisms to psmgmt, enhancing its ability to simulate real-world operating system behaviors.

Quick Start Guide 🚀

LOG_LEVEL is controlled in src/globals.c, but this will soon be commandline option.

Compile the Program

Compile both the psmgmt and worker executables by running:

make

Running psmgmt

The psmgmt program supports several command-line options to customize the simulation:

• -n <total_processes>: Set the total number of processes to spawn.
• -t <time_limit_for_children>: Set the time limit (in seconds) for each child process's lifespan.
• -i <interval_in_ms_to_launch_children>: Set the interval (in milliseconds) between launching child processes.
• -f <logfile>: Specify the log file for psmgmt output.

Example Command:

To launch a simulation with the updated features:

./psmgmt -n 10 -t 7 -i 100 -f psmgmt_log.txt

Cleaning Up

To clean up and remove all compiled files, run:

make clean
