New IBM XL compiler versions now available!
By: Bill Buros.
IBM has released the IBM XL C/C++ Version 12.1 and IBM XL Fortran V14.1 products for use on PowerLinux systems.
Over on developerWorks, there are two good articles on "what's new" with these new versions.
IBM provides run-time libraries and add-on packages as well.

On May 11th, Fedora announced a beta for F17 for ppc64. This is another milestone in the march towards Fedora 17 for the powerpc architecture.
The beta announcement itself can be found here ->
Yeah, lots of packages have been updated and so forth but there are two interesting pieces I'd like to draw some attention towards. Firstly, adoption of grub2 continues in the beta. We smoothed out some of the rough edges since the alpha timeframe and have a number of additional patches we'll push as well.
Secondly is that rpm and yum now are equipped to deal with a ppc64p7 subarch. I'll write up more on this topic as we near or pass Fedora 17 General Availability, but the basic function is that we have a POWER7 subarch (akin to i686 for x86) where certain optimizations are passed to the binary rpms. This is an exciting time for the architecture and Fedora!
Stay tuned as we catch our breath and begin to share more!

|System Backup for IBM PowerLinux |
By: Bill Buros.
Thought I'd take a minute to post a quick pointer to a system backup product that can be used on Power systems running Linux - the Storix System Backup Administrator (SBAdmin).
It's good to see a product specifically targeted at our PowerLinux customers!
By: Jeff Scheel.
It's been a few weeks since I have posted. I was on-the-road, doing what I affectionately call "dog on pony shows" where I am "just a dog." The trip started with 4 days of business meetings in Birmingham, UK. Most of these included presentations at the IBM STU on PowerLinux Trends and Direction as well as the IBM Software Development Toolkit. Following the event, we met with various customers, business partners, and system integrators in Bracknell, UK; Amsterdam, NL; and Brussells, Belgium.
Let me show my engineering background and provide my thoughts as a list (Sorry, Mom, I know paragraphs are preferred forms of writing, but as you know, I didn't did better in Engineering than English classes):
- The new PowerLinux servers are a great conversation starter. The competitive Total Cost of Acquisition (TCA) story eliminates the largest barrier to starting any discussion. If you have not already priced one out, pick your solution and learn more here.
- Many customers and partners are excited about emerging solutions in the area of Big Data Analytics. While they may not yet be implementing solutions, they all agree they have large volumes of unstructured data from which they will be attempting to learn in the coming years. The knowledge that PowerLinux is already focused on this solution space provides assurance of a roadmap forward.
- PowerLinux has made a program commitment to providing value-add that is resonating with who appear tired of owning the integration and support for separate hardware and software components. IBM's commitment begins with our investment in Linux as a technology lead by the IBM Linux Technology Center. To us in IBM's LTC, Linux is much more than software which runs on IBM HW: Linux is a vibrant community creating industry leading software based on values of open source software. On top of this foundation, PowerLinux delivers additional value to customers and partners through many aspects including delivering systems pre-installed with Linux, providing an optional Installation Toolkit for customers unfamiliar with Linux Installation, maintaining a YUM repository of value-add tooling for Linux-savvy customers, documenting extensively Linux use on Power Systems and PowerLinux servers through the IBM Information Center, facilitating application creation and porting through the PowerLinux Software Development Kit (SDK), supporting PowerLinux with IBM's world-class support capabilities just like our other Power operating systems, and committing to a technical community (this one) where all of these programs can be anchored, organized, and shared.
- The PowerLinux commitment to an SDK will be instrumental to the application ecosystem beyond what even I imagined. Our goal remains to provide a single integration point for PowerLinux application development on x86 hardware that is friendly and recognized to Linux application developers (Eclipse). We've only just begun this journey, but our tools which today are still running natively on PowerLinux are providing such dividends that customers are starting to ask if they should do their Linux and AIX application development with them. So, if you and/or your company have Linux applications (homegrown or formal offerings), be sure to take a look at our toolkit. It's free and we'll take your feedback on the community message board! Here's a link to the session presentation detailing many of the features of the toolkit.
That's all for now. As usual, comments, feedback, and questions are always welcome.

Today's acronym IPL
Given the announce of PowerLinux, you might actually hear us start to use this acronym more frequently as a reference to the IBM PowerLinux program. This is an unofficial, not sanctioned by the Big Blue Zoo, use of an acronym. But, it indeed is one worthy of tucking into your Rosetta Stone should you meet one of us on the street and we slip up.
I would like to point out, that this acronym does have an official use inside IBM for I
oad which basically means "booting" as in "starting". Those of you with AS/400 or mainframe heritage, will recognize that term. Detailed reading
on the topic can be found in the IBM Power System Information Center.
If you have heard an acronym and want us to explain, feel free to let us know.

For those who want to use Hadoop in a PowerLinux cluster to process large sets of data, this tutorial helps building the last Hadoop release from Community (1.0.3) and how to install it.
More information on Hadoop:
From the Apache web page, Hadoop is defined as "a framework that
allows for the distributed processing of large data sets across clusters
of computers using a simple programming model. It is designed to scale up
from single servers to thousands of machines, each offering local
computation and storage. Rather than rely on hardware to deliver
high-availability, the library itself is designed to detect and handle
failures at the application layer, so delivering a highly-available
service on top of a cluster of computers, each of which may be prone to

Life as the PowerLinux Chief Architect involves answering many questions, some of which need lengthy explanations. One such example is whether PowerLinux is a Power operating system or a Linux operating system. In some ways this discussion reminds me of the campfire scene from the 1986 movie Stand by Me
where the boys deeply contemplate Disney characters. Essentially the discussion went this way: Mickey's a mouse, Donald's a duck, Pluto's a dog, what is Goofy? The discussion about PowerLinux generally follows similar flow: IBM i OS is a business operating system, AIX is a UNIX operating system, Linux is an open source (x86) operating system, what is PowerLinux?
Ironically, one of the answers to the "What is Goofy?" question, is "He can't be a dog. He drives a car and wears a hat." That sounds like some reactions we get to PowerLinux: it can't be industry standard because it runs on the Power platform. It must be IBM's own Linux. Pardon the pun, but many people believe that PowerLinux must be "Goofy".
Simply put, PowerLinux strives to be "a Linux" first. To break this premise would invalidate the core value of Linux as the most prolific, cross-platform operating system. PowerLinux supports this premise so confidently that we've included it in our value proposition: Industry standard Linux, tuned to the task. As I've discussed in previous blog entries, PowerLinux is the same Linux operating system by Red Hat and SUSE, built from the same source, comprised of the same package versions, and delivered on the same schedule. IBM embraces this commonality and further works to actively eliminate as many barriers as practically possible. For example, we are actively working in the grub2 community to enable Power as a supported platform. This will enable us to use the same bootloader as x86 in future Linux releases. While most end users will never see the bootloader, PowerLinux remains committed to keeping Linux standard.
In some specific instances we extend Linux capabilities with Power operating system capabilities. Examples of this scenario include tools which are common to other Power operating systems like the rsct tools for HMC-client OS communication, drmgr for dynamic LPAR operations, and lsvpd for reporting device information. Most of these tools have software that is enabled more efficiently by having a common interface. None of these tools replace existing Linux tools.
Where I draw the line in being a Power operating system is in areas which clearly have Linux equivalents. For example, installation from NIM servers is an area where PowerLinux has traditionally not invested. While it is possible to perform such installs and some folks have graciously documented how to do so, IBM invests very little in ensuring this capabilities work. Instead, we focus on Linux installation through kickstart, yast, and anaconda as enabled by the Linux vendors.
So, with those examples, I hope you now have a greater appreciation for PowerLinux and agree that we are a "Linux," not a "Goofy".

One of the key aspects of Linux that runs on IBM Power Systems is it relies on industry standard Linux. In other words, there's a lot of investment in good cooperation with the Linux community, as well as with our distribution partners, such as your "Linux" install experience, for instance, is pretty much like Linux on other platform.
This specifically means if you are no stranger to Linux, or even if you already hold investments on top the existing installation technologies like Red Hat's Anaconda, or SUSE's Yast, you will find yourself in a familiar territory.
In addition, there's always a great focus on how much time does an IBM Power Systems customer takes to get productive, therefore you will also find IBM providing advanced service and productivity tools, as in the PowerLinux Service and Productivity portal
. As you will be able to observe, there are tools ranging from exploitation of advanced RAS and DLPAR capabilities on Power Systems, configuration and initial tuning of open source workloads and convenient access to useful software such as IBM's JVM.
From there, you will also be able to spot another interesting resource, the IBM Installation Toolkit
, whose goal is to further simplify the Linux installation process, specially for those new to Linux, while delivering all the added value service and productivity tools at the same time.
Last, but not least, IBM also provides customers with a nice Linux pre-load offering, meaning you can order your shiny new IBM Power machine and request that it comes pre-installed with your choice of RHEL or SLES, plus all the nice goodies from the Serviceability and Productivity portal.
But since with great flexibility, comes great responsibility, one of the questions people usually ask around is how to make the best use of all those nice aids IBM puts together, to help you become productive faster. Certainly a fair question, and the answer depends on a few factors:
- If you are just about or planning to acquire a new IBM Power System, usually the Linux pre-load option offers you a good value. The small "gotcha" is that it may not be available in all geographies/markets, at this moment.
- If you already have Power Systems around, and hold investments on Linux installation technology, or even are a Linux savvy individual or organization, simply check out Red Hat's and SUSE's documentation on the subject, in addition to the POWER7 System documentation, and you should find all you need to get Linux going. After you are done with those, you will find useful to check out the instructions on how to hook up your system, in to the IBM PowerLinux Tools YUM repository. You will get the Service and Productivity tools, the Linux way.
- If you are new to Linux, or would like to try something a bit faster to get both Linux and the service and productivity tools, all together, then I'd refer you to IBM's nice and free PowerLinux installation helper tool, the IBM Installation Toolkit. It nicely front-ends Linux installation, as well as packs all the important service and productivity tools, so you get to the up and running system, with fewer steps.
Hopefully, with all of that, you will have the right pointers to get you productive as fast as possible with Linux running on IBM Power Systems. So time to give a try to one of these options and drop your comments. You can certainly count that IBM will try to go above and beyond the commodity space.

Thibaud, great question. I copied the question over to the Message Board
where it will be easier to have a conversation.
I installed Fedora 17 on a POWER7 blade with virtual DVD from IVM. It ran smoothly, but IP address is provided by DHCP, which I want to change.
For some reason, I can't edit
because / is mounted in read-only mode. How come ? Of course, I am logged as root...
Please advise on how to fix this.
