CPU调度:调度标准(CPU Scheduling: Scheduling Criteria) There are many different criterias to check when considering the"best"scheduling algorithm, they are: 在考虑“最佳”调度算法时,有许多不同的标准要检查,它们是: CPU利用率(CPU Utilization)
The main objective of this paper is to introduce a new CPU algorithm called CPU scheduling Algorithm which acts as both pre-emptive and non-pre-emptive based on the arrival time. The proposed algorithm helps to improve the CPU efficiency in real time uni-processor, multi-programming operating ...
Multi-level FeedBack queue-scheduling algorithm, however, allows a process to move between queues. The idea is to separate processes with different cpu-burst characteristics. If a process uses too much cpu time, ti will be moved to a lower-priority queue....
The aim of this assignment is to investigate the performance of different CPU scheduling algorithms. You will use a discrete event simulator to conduct experiments on different processor loads and schedulers, and analyse the results to determine in which situations each scheduling algorithm works most ...

Suppose that a scheduling algorithm (at the level of short-term CPU scheduling) favors those processes that have used the least processor time in the recent past. Why will this algorithm favor I/O-bound programs and yet not permanently starve CPU-bound programs? 相关知识点: 试题来源: 解析...

1. First-Come First-Served Scheduling It is a simplest CPU scheduling algorithm. According to this, the process that requests the CPU first is allocated at the CPU first.FCFSis managed with the help of the FIFO queue. When a process enters into a ready queue it will link up at the tail...
