Change quantum value in cloudsim stimulator

Question

It is possible to change the quantum value when I use the CloudleschedulerTimeShared in order to apply Round robin algorithm for scheduling the tasks.

Answer 1

Such a feature is not implemented in CloudSim. If you try CloudSim Plus, it has an implementation of the Linux Scheduler that defines the quantum based on the priority you give to Cloudlets. Check the CloudletSchedulerCompletelyFair class.

You just need to create VMs, set this scheduler and define priorities for your Cloudlets. In this case, the priorities must lay between [-20 and 19]. Below is an example snippet:

vm.setCloudletScheduler(new CloudletSchedulerCompletelyFair());
for(int i=0; i < 10; i++){
    Cloudlet c = new CloudletSimple(CLOUDLET_LEN, CLOUDLET_PES);
    c.setPriority(i);  //you must define the priority in your own way
    cloudletList.add(c);
}
