This assignment will introduce you to CPU scheduling.

Specifications

You are to simulate the execution of processes by a computer system with a large

memory, one terminal per user, a CPU, and one disk drive. Each process will be

described by its class $($REAL$-$TIIE or INTERACTIVE$)$ and its start time followed by a

sequence of resource requests.

These resources requests will include CPU requests $($CPU$),$ diak reads $($DISK$)$ and

terminal accesses $($TTY$).$ In addition, all real$-$time processes will have a DEADLINE, by

which they must complete.

Your input will be a sequence of pairs as in:

All time will be expressed in milliseconds.

Your program should maintain separate ready queues for real$-$time and interactive

processes and give absolute priority to real$-$time processes over interactive processes:

a$)$ Your scheduler should never allocate the CPU to an interactive process as long as

there are one or more real$-$time processes in the ready state.

b$)$ When a real$-$time process returns to the ready queue and finds that the CPU is

currently allocated to an interactive process, the scheduler should take the CPU away

from the interactive process and give it to the real$-$time process. The pre$-$empted

process should return to the end of the ready queue for interactive processes. When

this is the case your program should update the duration of the CPU request by

subtracting from the original duration the time the process has already spent in the

running state.

Disk scheduling will be strictly first$-$come forst$-$senved $($FCFS$)$ without any distinction of

process classes.

To simplify your life, we will also assume that:

a$)$ there is enough memory space for all processes,

b$)$ context switch times can be neglected,

c$)$ user think times are included in the terminal access times, and

d$)$ each process reads and writes to a different terminal.

Your program should read its input file name through input redirection as in:

$./$a$.$out $$ input. txt

If by accident, two resources allocations need to be made at the same time, you should

allocate the CPU first then the disk and then the terminals.

Your program should have one process table with one entry per process containing a

process sequence number, the process class, its process arrival time and its current status

$($READY$,$ RUAMSING, WAITING$).$

It should print out one line of output every time a process starts or terminates. This line

should include the process sequence number, its class and the current simulated time in

milliseconds.

When all the processes in your input stream have completed, your simulator should print

a summary report listing:

a$)$ the number of real$-$time processes that have completed,

b$)$ the percentage of real$-$time processes that missed their deadline,

c$)$ the number of interactive processes that have completed,

d$)$ the total number of disk accesses,

e$)$ the average duration of a disk access $($including the waiting time in the disk queue$),$

f$)$ the total time elapsed since the start of the first process,

g$)$ the CPU and disk utilizations, that is$,$ the fraction of time the CPU or the disk was
