Description:
Assignment 2
OS Fall 2001
Multi-level scheduling queue.
Write in C

You are to simulate scheduling jobs in a multi-level queue system.
There are 5 queues corresponding to the different priorities of the jobs.
(A priority of 1 is the highest priority, 5 is the lowest.)
There are 15 jobs, with the following running times and priorities.

job number 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
times 6 4 8 3 8 2 4 8 7 6 3 7 3 4 7
priorities 1 3 1 2 4 3 5 4 1 4 1 3 2 4 1

There are 6 processors and a job can be scheduled in any one of the
processors. There is an internal clock. A scheduled job (process) is given
3 time quantums, at which time the job is given a lower priority and moved to
the end of the queue for the new priority.


The information that you will probably want to keep will be:

int process_number
int total_time_required
int time_to_finish
int slice_remaining
int priority



Suggested logic of the program

Get the data and build the priority queues
start the first group running
display the queues;
display the running processes

repeat
increment 1 time slice
while a process is done or the time quantum has expired
remove the process from the running state
decrease the priority of the process
insert the process into the new wait queue (on the end)
Remove a process form the highest queue with a process waiting
start running the process
end while
display the running processes
display the queues
until all_queues_empty;

while someone is processing
do_one_time_slice;
kill any processes whose time has expired
display the running processes;
end while

I do have the corrected output, I will send it to you once i accept yr bid
