eServer Developer Domain: Advantages of OpenMosix on IBM xSeries [Parts 1-3]

Dec 18, 2002, 05:30 (4 Talkback[s])
(Other stories by Daniel Robbins)

From Part 1:

"In this three-part series, I will introduce you to a clustering technology for Linux called openMosix. As you may know, clustering technologies allow two or more networked Linux systems (called "nodes") to combine their computing resources to solve computing challenges faster than would be possible if they were tackling the problem on their own. Choice of hardware is flexible of course, and openMosix is not limited to any single hardware platform, but clusters built on IBM xSeries servers running Intel® Xeon™ processors will have some unique advantages. Making use of performance-enhancing technologies such as Intel's Hyper-Threading Technology, now supported under Linux, improves the performance of multi-threaded applications by allowing a single Xeon processor to appear to the operating system as two virtual processors. By taking advantage of Hyper-Threading, you can benefit from having multiple physical and/or virtual processors and also enjoy the benefits of openMosix itself. As this series progresses, I'll guide you through the process of setting up your own openMosix cluster. By the end of the series, you'll have your own openMosix mini-cluster up and running and will be ready to use it to effectively accelerate your computing tasks.

"In this first article, I'll provide you with a very clear and understandable introduction to the current clustering technologies available for Linux and then introduce you to openMosix. I'll also explain how openMosix compares to other more traditional Linux clustering technologies, as well as point out differences and similarities between openMosix clusters and multi-processor computers. By the end of this article, you'll have all the necessary background to prepare you for setting up your own openMosix cluster. As you might guess, I'll show you how to do that in part 2 of this series..."
