The Beowulf Project
Beowulf is one of the most exciting projects using Linux today. Originating from the Center of Excellence and Information Sciences (CESDIS) at the NASA-Goddard Space Center in Maryland, the project's mission statement is:
Beowulf is a project to produce the software for off-the-shelf clustered workstations based on commodity PC-class hardware, a high-bandwidth internal network and the Linux operating system.
The Beowulf project was conceived by Dr. Thomas Sterling, Chief Scientist, CESDIS. Donald Becker, a Scientist at CESDIS, wrote the fast-Ethernet drivers needed for the Beowulf-class clusters and incorporated them into Linux. One of NASA's imperatives has always been to share technology with universities and industries. With the Beowulf project, NASA has provided the Linux community with the opportunity to spread into scientific areas needing big computing power.
Our cover is a picture of the Beowulf-class cluster, Loki, used at Los Alamos National Laboratory. For more information about this cluster and the Hyglac cluster at Caltech, see our feature article I'm Not Going to Pay a Lot for This Supercomputer! by Jim Hill, Michael Warren and Patrick Goda. There are also clusters of this type at Drexel and Clemson Universities.
Next month, our focus will be on databases, and we have articles on development, PostgressSQL, SQL in Python and a free database called Qddb. I think you will find them all enlightening. We will also feature an article about Digital Domain, a production studio that does digital special effects for the movies. Digital Domain used 105 Alphas running Linux and connected by fast Ethernet to create many of the effects used in the upcoming motion picture Titanic.
The goal of this symposium is to bring together researchers, practitioners, system programmers and others interested in the latest advances in security and applications of cryptography. This will be a four-day symposium with two days of tutorials, followed by two days of refereed paper presentations, invited talks, works-in-progress presentations and panel discussions. It will be held January 26-29, 1998 at the Marriott Hotel in San Antonio, Texas. For more information contact the USENIX Conference Office via e-mail at email@example.com.
We've updated our Linux Resources web pages—check them out at http://www.linuxresources.com/. In addition to the usual sections pointing to Linux distributions, FAQs, HOWTOs and Newsgroups, we have:
Linux Speaker's Bureau: a list of people willing to give Linux talks and their areas of expertise.
Employment: a place to go to find a job or the right person for a position utilizing Linux.
Business Connection: information on how to promote Linux in the workplace.
Linux Projects: a list of current projects being developed in Linux and a message board for posting ideas for projects.
G.L.U.E.: Groups of Linux Users Everywhere, provides information on starting a LUG, setting up trade shows and more.
Linux Library and News: places to find the latest information about what's happening in Linux.
We also are providing space for people in the Linux community to post their information about Linux, so that it can be found in one area rather than scattered over the web. Write to firstname.lastname@example.org if you wish to make use of this space. Because we wish this Linux Resources area to be a community effort to promote Linux, we have kept it non-vendor specific and advertisement free.
Several months ago a light bulb went off and we had what we thought was a great idea—turn subscriptions over to a fulfillment house. Our Associate Publisher did a lot of research to find companies that performed this service and that could accept e-mail orders. We then picked one that seemed to best fit our needs. In September, we turned subscriptions over to Superior Fulfillment in Duluth, Minnesota, expecting to no longer have to worry about this aspect of the magazine. Well, we were wrong. Murphy's Law took over and everything that could go wrong did. Superior kept delaying the date when they would have all of our orders entered into their system. It was time to get label information to the printer, and we didn't have it. We began to get angry letters from new subscribers. Finally, we had to give up on being able to fix the situation long distance. Superior returned all of the subscription orders to us, and the majority of LJ's staff spent the next couple of weeks entering orders and writing letters to our subscribers. The insert cards in the November and December issues of LJ all have the Duluth, MN address, but now it's back to Seattle.
We are most sorry for the inconvenience that this situation has caused our customers and hope that you will all forgive us. To us, our subscribers are the most important people in the world, and we wish to give you the best possible service. Thanks to all of you who showed us such patience and understanding during the time period when it seemed like all orders were lost.
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
