For this project we'll be building a simple process scheduler that takes in a file containing example processes, and outputs a schedule based on the three different schedule types:
First Come First Serve (FCFS) [already done]
Shortest Job First (SJF) preemptive
SJF Priority
Round-robin (RR)
Assume that all processes are CPU bound (they do not block for I/O).
The scheduler is written in Go (a skeleton main.go is included in the project repo).
Steps
Clone down the example input/output and skeleton main.go:
In your go.mod, replace "jh125486/CSCE4600" in the module line with your GitHub username and repo, e.g.:
"module github.com/jh125486/CSCE4600" changes to "module github.com/CoolStudent123/ShweetScheduler"
The processes for your scheduling algorithms are read from a file as the first argument to your program.
Every line in this file includes a record with comma separated fields.
The format for this record is the following: <ProcessID>,<Burst Duration>,<Arrival Time>,<Priority>.
Not all fields are used by all scheduling algorithms. For example, for FCFS you only need the process IDs, arrival times, and burst durations.
All processes in your input files will be provided a unique process ID. The arrival times and burst durations are integers. Process priorities have a range of [1-50]; the lower this number, the higher the priority i.e. a process with priority=1 has a higher priority than a process with priority=2.
Start editing the schedulers.go and add the scheduling algorithms:
Implement SJF (preemptive) and report average turnaround time, average waiting time, and average throughput.
