The guest OS can run on the VM as though the VM were a real physical machine. Popular hypervisors used widely for personal and cloud computing include VMware
Different goals and algorithms characterize process scheduling in real-time operating system. Schedules may or may not exist that satisfy the given timing
developing a technique which will separate important SMS files into a different priority inbox Android operating system uses O (1) scheduling algorithm.
In this paper I propose a MLP aware operating system (OS) scheduling algorithm for Multithreaded Multi-core processors. By observing the MLP available in
A Unitary standard that must be accomplished through scheduler is reducing the average waiting time for the processes entirely [9]. The operating system. Page 2

Multi-Processor Scheduling There are two approaches Asymmetric: one processor does the scheduling and other kernel jobs (no need to synchronize) Symmetric: each processor is self scheduling This is more complex as all processors need to access shared data Most systems do Symmetric Multi-Processing with either A global ready queue
2 SCHEDULING: INTRODUCTION afully-operational scheduling discipline1 We will make the following assumptions about the processes some- times calledjobs that are running in the system: 1 Each job runs for the same amount of time 2 All jobs arrive at the same time 3 Once started each job runs to completion 4
UNIX scheduling • Canonical scheduler is pretty much MLFQ – 3-4 classes spanning ~170 priority levels • timesharing: lowest 60 priorities • system: middle 40 priorities • real-time: highest 60 priorities – priority scheduling across queues RR within • process with highest priority always run first
Schedulers Decides which process should run next Aims Minimize waiting time Process should not wait long in the ready queue Maximize CPU utilization CPU should not be idle Maximize throughput Complete as many processes as possible per unit time Minimize response time CPU should respond immediately Fairness Give each process a fair share of CPU
