Small Systems and Big Iron: Linux on Non-x86 Computers
Of the platforms discussed in this article, Power and especially Itanium both have a questionable future. Although IBM and Intel are committed to developing future generations of their products, the market for high-end proprietary processors has been somewhat eroded by increasingly fast and cheap x86 processors. Many analysts felt that the Tukwila Itanium was underwhelming in comparison to both Power7 and high-end x86 server processors, such as recent Xeon and Opteron chips. IBM expects Power to be a viable platform for a long time, because it still is substantially faster than the x86 alternatives, but even for them, competition is closer than it once was. As a result, Linux support for these platforms probably is going to decline over time, although as long as there is hardware using these architectures, people will be using and developing Linux on them, as has happened with “dead” architectures, such as the DEC Alpha and the HP PA-RISC. ARM, on the other hand, has a bright future, having been dominant on low-power systems for decades and starting to become popular on consumer computer hardware, with constantly improving Linux support.
Kira Scarlett has been using Linux for eight years. She frequently ends up owning strange and unusual computer hardware, and she has used Linux on almost every major processor of the last 20 years. She also is interested in graphic design and is an avid hockey fan. Kira can be reached at firstname.lastname@example.org.
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
