The numbers of algorithms are proposed to schedule real time transactions in order to produce the overall performance. 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...
SCAN scheduling algorithm is also called the elevator algorithm because in such kind of algorithm arm behaves just like an elevator for building the way. In the SCAN algorithm, the arm will start at the one end of the disk and then move towards another end of the disk. At the last end,...
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调度算法,对于磁盘...
12.The method of claim 11 wherein the disk scheduling algorithm continuously adjusts the values for C and L to optimize the writing of data to the disk. 13.The method of claim 12 wherein the value for C is taken to be the minimum of all observed writes to the disk. ...
7. A tangible machine readable medium embodying computer program instructions for executing an application in a virtual machine running on a local user system, wherein the virtual machine accesses a virtual disk, the computer program instructions causing the local user system to perform a method com...
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...

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 ...
