How can we specify the execution time for any virtual machine (vm) in cloudsim simulator

Question

if we have 50 cloudlets/tasks and 1 virtual machine (vm) how can we make vm to run for specific time in order to apply RR method and cloudelts are run in time slice or quantum

Answer 1

In fact, CloudletSchedulers in CloudSim don't implement the concept of time slice/quantum.

If you need to assess Cloudlets' preemption process, you can check CloudSim Plus, it's a full-featured, state-of-the-art, completely re-engineered and actively maintained CloudSim fork. It provides an implementation of the Completely Fair Linux Scheduler that performs actual preemption and considers a time slice/quantum to run Cloudlets. Check the CloudletSchedulerCompletelyFair and the LinuxCompletelyFairSchedulerExample.
