Minimum CDT based Scheduling Algorithm versus FCFS in Grid Environment

To achieve the promising potentials of tremendous distributed resources, effective and efficient scheduling algorithms are fundamentally important. Unfortunately, scheduling algorithms in traditional parallel and distributed systems, which usually run on homogeneous and dedicated resources, e. g. computer clusters, cannot work well in the new circumstances. In this research paper, MJ_CDTmin [1]...

Disk Scheduling: Selection of Algorithm

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 algorithms” in particular. Key word: Disk scheduling, Selection of algorithm.

An improved parallel disk scheduling algorithm

We address the problems of prefetching and I/O scheduling for read-once reference strings in a parallel I/O system. Read-once reference strings, in which each block is accessed exactly once, arise naturally in applications like databases and video retrieval. Using the standard parallel disk model with D disks and a shared I/O buffer of size M , we present a novel algorithm, Red-Black Prefetchin...

A New Heuristic Disk Scheduling Algorithm

Since the invention of the movable head disk, people have improved I/O performance by intelligent scheduling of disk accesses. Processor speed and memory capacity are increasing several times faster than disk speed. This disparity suggests that disk I/O performance w ill become an important bottleneck .Methods are needed for using disks more eff iciently. Past analysis of disk scheduling algori...

A Disk Scheduling Algorithm Based on ANT Colony Optimization

Audio, animations and video belong to a class of data known as delay sensitive because they are sensitive to delays in presentation to the users. Also, because of huge data in such items, disk is an important device in managing them. In order to have an acceptable presentation, disk requests deadlines must be met, and a real-time scheduling approach should be used to guarantee the timing requir...
