This paper presents the overview of existing approaches for scheduling the real- time transactions. Earliest Deadline First (EDF) is a basic algorithm which meets the real time constraints, but it gives poor disk throughput. Adaptive Earliest Deadline (AED) improves the performance ...
422_磁盘调度算法 各位同学大家好,在这个小节中我们会学习一个很重要很高频的考点磁盘调度算法,首先我们会介绍一次读磁盘操作或者一次写磁盘操作到底需要多少时间,我们应该怎么计算。它总共分为寻道时间、延迟时间和传输时间这样三个部分 磁盘调度算法的不同会影响寻找时间的长短,所以选择一个合适的磁盘...
disk schedulingdiscrete firefly algorithmseek timeThis study empirically investigates the usage of a customized discrete firefly algorithm (DFA) for ordering the disk requests to minimize the total access time. The procedure simulates the movement of each firefly within a population towards others using...

In this paper, a new cache-scheduling algorithm for the disk array, called track-based improved LRU algorithm, is proposed. The basic element, during the scheduling, is a track of disk drive. It is the combination of read-ahead caching, fast-write, elevator write-back and LRU replacement ...
We present a real-time disk scheduling algorithm, Concurrent DS-SCAN (CDS-SCAN), which maximizes throughput for modern storage devices by allowing concurrent I/O requests at the device whenever possible. Past real-time disk scheduling algorithms allowed a single request at a time to go to the ...
For high-performance computing, the disk scheduling algorithms also need to be optimized along with optimization of CPU scheduling. The proposed scheduling algorithm improves the performance measure of the disk scheduling algorithm by reducing the seek time, the rotational latency, and the platter ...
The objective of this paper is to take some aspects of disk scheduling and scheduling algorithms. The disk scheduling is discussed with a sneak peak in general and selection of algorithm in particular.doi:10.1007/s12646-015-0323-9Yashvir, S...
