Help on my OS assignment!!
Hie,
Does anyone fimiliar in writing a program on cpu schedulling in C++
mainly on SJF, Round Robin and Priority!!..im a newbie in C++ so i
need guidance on doing this program... Hope that anyone is kind
enough to help me...
Thanks...
The Assignment goes like this:
Project 1
Develop a program to simulate a computer using a Round-Robin
scheduling algorithm with a time slice of 10 milliseconds and with a
ready queue but no device queue. Assume that each process has a
random service time of 1 to 9 seconds. Accept processes over a 20
seconds period but continue the simulation until all processes are
complete.
Project 2
Develop a program to simulate a computer using a preemptive Shortest
Job First scheduling algorithm with a ready queue but no device
queue. Assume that each process has a random service time of 1 to 9
seconds. Accept processes over a 20 seconds period but continue the
simulation until all processes are complete.
Project 3
Develop a program to simulate a computer using a scheduling
algorithms based on a preemptive Priority scheduling. Each process
is assigned a random integer priority from 1 to 8. In case two
processes have the same priority, the first process submitted
executes first. Assume that each process has a random time of 1 to 9
seconds. Suppose the execution time is never more than the
exponential of the priority.

Hello friend ,
I have not done CPU Schedulling but we have done memory
mgmt in C++ long back (as our MCA II nd Sem Assginment ). Check it if
it can help you .
Keep posting

What grade of program do you want? Just simulation? Or
a routine to be plugged into a kernel? Please tell us
in details, probably then a solution can be thought
of. BTW, if C (not C++) will suffice, you can take a
look at the scheduler of the Linux kernel
(www.kernel.org).
Regards,
Shantanu
