By: Anibal Carvalho . One of the
main new features of IBM® Installation Toolkit for PowerLinux version
5.3 is the support for facilitating Linux installations, on top of multipath devices. Multipath I/O Linux layers can be enabled on IBM PowerLinux servers with multiple physical paths to storage devices (through SANs or direct attached), where they can be used to increase storage path redundancy, as well as to enhance server performance though typical features, such as: Dynamic load balancing Traffic shaping Automatic path management...

By: Beth Taylor and Walt Madden. Several previous blog posts have told of the
advantages of IBM ®
Advance Toolchain for PowerLinux for application performance analysis on IBM
Power Systems ™
servers. Likewise, you've heard about
IBM Software Development Kit for PowerLinux ™ , which combines C/C++ source
development with the Advance Toolchain and classic Linux debugging and
performance analysis tools like OProfile. Recently, the IBM InfoSphere Streams development
team has had the positive experience to give credit to these claims... [More]
By: Bill Buros. Within the Linux open-source community, and across the Power systems, there are a number of new, emerging, and in some cases maturing technologies actively being worked on, prototyped, and prepared for enterprise-class deployment. Members of the IBM Linux Technology Center around the world are involved with these projects, collaborating with peers across the open-source community. Over the coming weeks and rolling into next year, here on the PowerLinux Technical Community we plan to begin highlighting these technologies in... [More]

By: Rafael Folco. Practical experiences with setting up a cluster
I recently have had the opportunity to work with the IBM InfoSphere BigInsights product on PowerLinux. From these experiences, I created a wiki page which describes some hints and tips on setting up a cluster for BigInsights. The BigInsights product provides for serious hadoop-based processing and is available on the PowerLinux base. If you have questions on taking advantage of BigInsights and hadoop on Power systems, ask a question on the PowerLinux message... [More]

Besides the unique location, this event really forced me to consolidate my thoughts into a concise message on PowerLinux. Here were the 3 main points (all good things come in three's...it's the "magic number"): PowerLinux... [More]

Today's common question comes to us from many different sources. What prompts the write-up today is a nice description I recently saw in an email. Question: How hard is it to migrate applications to PowerLinux?
Answer: It depends on the characteristics of the application, but generally speaking migration is simple and straightforward. Post migration, the real work can be in tuning performance sensitive applications which typically contain more assembler and non-portable, platform-unique code, two attributes which... [More]

By: Jeff Scheel. As I've often mentioned in my blogs, I like to answer questions which I've been very asked frequently. Today's topic provides more details about our marketing slogan "Industry standard, Tuned to the task". We've worked so hard to eliminate the myth that PowerLinux is different (see my blog What does IBM mean when it says, "PowerLinux?" ) that we're now getting questions like:
Will my (x86) Linux application just run on PowerLinux? Can I use the same DVDs to install my PowerLinux or Power System server... [More]
By: Jessica Erber-Stark. They say a picture is worth a thousand words. If that's true, how many words is an information-packed video worth? The PowerLinux team has been hard at work, creating several videos to educate you on many aspects of the PowerLinux product. From product overviews to detailed technical demos, we can almost guarantee that you'll come away from these videos saying, "I didn't know I could do that with PowerLinux!" Check out the videos in the wiki at the PowerLinux videos page. We'd also love to hear your... [More]
By: Steve Champagne. Thanks to all who participated in the Kernel notifications for RHEL 5 running on 7R2 thread in the Message Board! Your conversation and insights led to the following new topic in the Linux Information Center: Diagnosing RTAS events .
By: Steve Champagne. For information about performance tuning on your PowerLinux system, be sure to see the A Tuning Guide for PowerLinux section of Performance Rocks - Best Practices . I added three new sections there today:
