Hi all pls help me with the soln to this probelm, the catch is the interface (menu) needs to be Built in C as well. Any suggestions would be of great help as well. Thanks It is a system written using a structured programming language (e.g. C, Turbo C) that simulates the following CPU Scheduling Algorithms:. First Come First Serve. Shortest Job First.
Srtf Cpu Scheduling Code In C Codes and Scripts Downloads Free. Bluedoc is a Tool for generating documentation in HTML format from doc comments in source code in C and C++.
Round Robin. Shortest Remaining Time First The user must be given the option to choose from any of the algorithms (Menu). Jobs arrive in the queue through manual input with the following required information: Job No. CPU Burst Time Arrival Time Status 1 2 3 4 5 Status can be Pending, Processing, Finished. The system should be able to check for invalid inputs and provide appropriate error messages to the user. The system then shows the movement of each job in the system (from the ready queue up to when it exits the system) plus drawing the GANTT Chart simultaneously. At the end of the simulation, the system displays the following information:.
Waiting time for each job;. Turnaround time for each job;. Average waiting time for the system; and. Average turnaround time for the system. The system then asks the user if he wants to simulate the same algorithm, simulate another algorithm, or to quit the system.
Here you will get C/C program for first come first served (fcfs) scheduling algorithm. What is First Come First Served (FCFS) Scheduling Algorithm? First Come First Served (FCFS) is a Non-Preemptive scheduling algorithm. FIFO (First In First Out) strategy assigns priority to process in the order in which they request the processor. The process that requests the CPU first is allocated the CPU first. This is easily implemented with a FIFO queue for managing the tasks. As the process come in, they are put at the end of the queue.
As the CPU finishes each task, it removes it from the start of the queue and heads on to the next task. Also Read: C Program. ↓. tina Hi Neeraj. Thanks for your helpful example here. Im trying to program for FCFS. All related examples online I found are for 1 server (machine) N processes (job).
Like in your example, 3 process would be processed in sequence by one server. However, in my case, I have several servers (let’s say I have 10 machines) and 100 processes (jobs).
I know about the arrival time of each job, i know how long each job would be finished (all machines have the same speed). Now I need to get a machine-job match based on FCFS. The difference of my case with yours is that I cannot assignment all jobs to a single machine. The constraints in my case is that for each job, it has its own several specific machines MAC to be assignment to. (1 job – 1 machine (this machine should be from MAC). So in my case, firstly I would make a list of jobs based on their arrival time; Then I would assign the first job with earlier arrival time to one of its suitable machines; Do the same to the second coming, the third and more.
I’m new in programming and wondering if you have programmed for similar cases. Any suggestions would be greatly appreciated.
