Beowulf Cluster Computing with Linux, Second Edition
Beowulf Cluster Computing with Linux provides a well-balanced discussion that covers the basic design and construction of a Beowulf cluster, as well as how to manage and effectively use one. The breadth of the discussion is the book's only weakness—a lack of depth. The book touches on several topics from networking to programming, but you're going to need other sources on each subject for in-depth discussions. This book can help you define what other resources you need, though.
This book is valuable for three audiences: management, system administrators and developers. For management, it provides enough information to become familiar with the concept of a Beowulf cluster and determine whether the effort and cost of a cluster is worthwhile. It provides you with enough information to evaluate vendor proposals, and it should provide enough information to assist in making the build/buy/lease decision.
System administrators can learn what is needed to build a cluster, as well as what is available for administering and maintaining it. The book has enough solid information to assist you in designing the right kind of cluster for your organization. It also can help you “right-size” your cluster as well as design a good evolution plan that allows your management to be confident in both your initial cost proposal and your ability to estimate the ongoing costs.
Developers can learn what tools and skills they need to make effective use of a cluster. The book offers a good foundation on how to develop applications that effectively use such a powerful tool. A lot of effort is required to develop a good application that effectively can use the potential of a cluster. This book provides you with enough information to determine whether your application is a good fit and how to move forward with the effort if it is. The book also contains basic information on the principle tools for developing for Linux clusters, as well as example code and guidance on application design.
Overall, this is an excellent book. Beowulf Cluster Computing with Linux was written for a broad audience and is well worth the money, even if you simply want to learn about Beowulf clusters. On the down side, Beowulf Cluster Computing with Linux is not the only volume you will need to buy to take full advantage of your new cluster.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
