Visual scheduling simulator.

Process scheduling algorithms:

• FCFS (first come first serve)
• SJF (shortest job first)
• SRTF (shortest remaining time first)
• RR (round robin)

Disk scheduling algorithms:

• FCFS (first come first serve)
• SSTF (shortest seek time first)
• SCAN
• C-SCAN
• EDF (earliest deadline first) - real time
• FD-SCAN (feasible deadline SCAN) - real time

Page replacement algorithms:

• FIFO (first in first out)
• OPT (optimal)
• LRU (least recently used)
• ALRU (approximate least recently used / second chance)
• RAND (random)

Frame allocation algorithms:

• Equal
• Proportional
• Page Fault Control (tries to keep fault frequency between set bounds)
• Locality Model (Polish: Model strefowy)

Load distribution algorithms:

• Random queries (N tries)
• Random queries until success
• Random queries until success + offloading

Installation

Install NodeJS (tested on v18.15.0). Run:

$ git clone https://github.com/brun0ne/scheduling-sim

Then in each of the src directories:

$ npm install
$ npx webpack -w

Motivation

I completed these simulations as assignments for my Operating Systems ("Systemy Operacyjne") course.
