[SOLVED] Csci 340 scheduling simulation programming project

The goal of this project is to implement a process scheduling simulator for the non-preemptive scheduling
algorithms discussed in the textbook.Your code will simulate the First Come First Served (FCFS), Shortest
Process Next (SPN), and Highest Response Ratio Next (HRRN) algorithms. Your simulator will allow the
user to compare the performance of the different algorithms in terms of average Wait Time and average
Turnaround Time.In addition, you will be required to submit a 2-4 page report explaining the project and addressing the
following items:
• Introduction — describe the project and goals
• Scheduling Algorithms — describe/define the three scheduling algorithms you are simulating. Provide
at least one advantage and one disadvantage of each scheduling algorithm in comparison to the the
other two. Construct and provide one example of scheduling at least 5 processes using each respective
algorithm. Use a table to keep track of the finish time, turnaround time, and wait time, similar to
what the author does in the textbook. Compute the average wait time and average turnaround time.You cannot use the author’s examples — create your own! NOTE: your examples are also great for
testing.
• Performance Metrics — describe/define the two performance metrics we are using.
• Simulation Algorithm — describe in English your simulation algorithm including what data structures
you use, what information you track, and how you keep track of simulation time
• Results — summarize the results of your simulator by comparing the average wait time and average
turnaround time for each of the three algorithms given 1000 processes and using 5 different random
seeds. Succinctly show these results graphically using bar graphs.The file, sched compare.c, contains a stubbed-out main() that you must use as described in the comments.
Any functions you require for your solution can easily be implemented within this file.
In addition, the following files are required by the stubbed-out main(). Don’t modify these files:
• poisson.c and poisson.h: These files are used by procs.c to generate an array of random process
arrival times and service times. If you are curious about the Poisson distribution, google it!
• procs.c and procs.h: These files contain routines to randomly generate process arrival times and
service times, read a list of arrival times and service times from a file, and print an array of process
arrival times and service times. See comments in the main() for how to call them.• procheap.c and procheap.h: These files are optional in your solution, but recommended. It is
useful to be able to sort arriving process according to some comparison criterion. For example, with
SPN, you will need to choose the minimal service time process among a set of processes that arrive
within an interval of time. A heap (priority queue) can be useful in making this determination.
In order to use the heap, you will have to initialize it with a size and value function, value func. An
example value function might be something like this:
1
double myvalue(proc_t *proc)
{
return proc->arrival_time;
}
The process structure, proc t, is defined in procs.h. Processes inserted into the heap initialized with
the value function above, will be prioritized (sorted) based on minimum process arrival time.This is an team assignment. Collaboration is only permitted between team members on the same
team. Plagiarism will not be tolerated. Submitted solutions that are very similar (determined by the
instructor) will be given a grade of zero. Please do your own work, and everything will be OK.
Submission
Create a compressed tarball, i.e. tar.gz, that includes your report in PDF format, the Makefile and all the
.h and .c files needed to compile and execute your program.
The name of the compressed tarball must only be the last name of one team member. For example, ritchie.tar.gz would be correct if the original co-developers of UNIX (Dennis Ritchie and Ken
Thompson) submitted the assignment. Only assignments submitted in the correct format will be accepted
(no exceptions). Only one designated team member will submit the compressed tarball to the Dropbox project folder on OAKS. Your team may resubmit the compressed tarball as needed. I will only use
the most recent submission.
Late assignments will not be accepted. Exceptions will only be made for extenuating circumstances, i.e.
death in the family, health related problems, etc. You will be given two weeks to complete this assignment.
Poor time management is not excuse. Do not email the assignment after the due date, it will not be
accepted.
Please feel free to setup an appointment to discuss this project. I am more than happy to listen to your
approach and make suggestions. However, I cannot tell you how to code the solution. Additionally,
debugging is your job. You may use the debugger (gdb) or print statements to help understand why your
solution is not working correctly.
Grading Rubric
For this assignment the grading rubric is provided in the table shown below.
program compiles 10 points
program runs with no errors 10 points
report 25 points
implementation of FCFS algorithm 15 points
implementation of SPN algorithm 15 points
implementation of HRRN algorithm 15 points
implementation of the main function 10 points
Of course, if your program does not compile, you will miss points for many of the other items.
