by Jeff Scheel, IBM Linux on Power Chief Engineer A great blog entry floated through my email inbox this week that raised a broader discussion topic for me: folks may have heard about the OpenPOWER Foundation, but may not know where to read the latest information. So, I thought I'd provide a few pointers. The OpenPOWER Foundation website is the starting point for all information about the foundation. When all else fails, start there. Under the site " News/Events " link at the top of the page, you will... [More]
By: Bill Buros. Saw this over on the IBM Research blog. Very nice! The IBM Power 775 is an amazing server. In this publish, Redhat Linux Version 6.2 is used. IBM’s Power 775 wins recent HPC Challenge Starting out as a government project 10 years ago, IBM Research’s high performance computing project, PERCS (pronounced “perks”), led to one of the world’s most powerful supercomputers, the Power 775. This July, the Power 775 continued to prove its power by earning the top spot in a series of benchmark components of the HPC Challenge... [More]

By: Jeff Scheel. From time to time, we have posted "expert" blogs in the PowerLinux community. I did the original "Experts" posting on August 1, 2011. Since then, we've also had postings by Bill Buros, Performance Architect, and Steve Munroe, Toolchain Architect . As we add more, we will make sure to tag them all with an "experts" tag such that you will always be able to find them easily in the blog. Here is a quick link that will always work. In the case that you are looking for an expert who has not been... [More]
The common standard benchmarks By: Bill Buros. After we have a new Power7 system installed and configured, we generally will run a set of performance benchmarks on the system to confirm that it's running things as we expect it to. In a performance lab like ours, we have the luxury of access to SPEC.org benchmarks, the latest IBM XL C/C++ and Fortran Compilers, the latest gcc-based Advance Toolchain libraries, and the full suite of performance tools and profilers installed on our systems. On a new system, we will regularly install,... [More]
Currently if you are planning to use docker on RHEL 7.1 LE, then one of the option is to download pre-built binary by following the instructions mentioned here . The other option is to build from source. Building from source is the preferred option if you want to use the latest upstream docker features. Building from source is pretty straight forward and this article will provide the detailed steps. The primary tool-chain for building Go programs on Power platform is GCC-GO. This is available starting GCC version 5 onwards. While GCC 5 is not... [More]
If you are running Ubuntu, there is a cgroup hotplug issue to consider when changing SMT modes. You may need to take steps to ensure that SMT threads are being used properly, see this article for more info.
Going to LinuxCon North America the week of the 17th in Vancouver? Wish I was.... By: Robert MacFarlan. Power Linux will be getting a bit of love at LinuxCon this year. IBM is sponsoring an extended Birds of a Feather / Beverage Social. Did you secretly want to be on Jeopardy and compete against Watson? You can at LinuxCon. There will be a "Mini Watson" demo outside the doors of the beverage social Did you know Watson ran on Power Linux? Paul Mackerras, PPC Maintainer for Linux, will also be demoing an interesting lab project... [More]
We've had recent reports that SLES 11 SP3 won't install on a POWER8 system. The install fails 5 seconds into the process with "Can't allocate memory for kernel image !" and stopping at the open firmware prompt. We're hunting down the root cause information (being in development makes me very curious about these things). But in the meantime, our esteemed colleague Nigel Griffiths nicely hunted down the work-around which is available on SUSE's web site... [More]
This topic came up again today - how can "I" <fill in your name> get a quick and easy Power Linux cloud deployment image up and running - using POWER8 systems and the latest Ubuntu 14.04 release? I've reported on this earlier - before the POWER8 systems actually became available - here on the DeveloperWorks community. May 15th 2014: SiteOx.com. My own Ubuntu on Power guest. May 16th 2014: SiteOx.com. Day two. I am impressed. Fast forward to today.... [More]
Alphabet Soup: xCAT By: Heather Crognale. When you're ready to provision a system in your cloud or cluster, you can go through each step on your own, or you can use the xCAT: Extreme Cloud (or Cluster) Administration Toolkit . The xCAT is a collection of tools, most of which are script-based,
that you can use to build, configure, administer, and maintain Linux clusters. You can use xCAT on any cluster, but it works particularly well on high-performance clusters, horizontal-scaling clusters, and administrative clusters. The xCAT can be used... [More]
By: Jessica Erber-Stark. Need a quick reference for setting up your Power Linux system? See Getting started with Linux on Power Systems Servers . After your system is up and running, use the IBM Installation Toolkit Simplified Setup Tool to easily configure open source workloads . Many of our Power Linux users also asked for a concise guide about setting up virtualization on their system. The Getting started with virtualization using PowerVM topic provides an overview of the roadmap for virtualizing your system, specifics about the... [More]
By: Ricardo Marin Matinata. 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... [More]
By: Brent Baude. Fedora 17 is now generally available for ppc64. The release notes are available at -> https://fedoraproject.org/wiki/Fedora_17_PPC_release_notes While Fedora 17 offers a ton of new features itself, some of the key features specifically for ppc64 are: Switched to grub2 from the traditional yaboot bootloader Updated to Firefox v12 Fixed multipath install issues in Anaconda Added feature to automatically set the install disk as the priority boot device Added the ppc64p7 subarch to yum and rpm, which allows for building...

by Rafael Folco <firstname.lastname@example.org>, OpenStack CI Engineer I've just published an article discussing some basic ideas for building a 3rd party Continuous Integration system. It covers important aspects to plan, install and configure a 3rd party CI environment to test OpenStack upstream patches. The article also explains how the CI services interact each other and what kind of customization you need to test your platform or driver on OpenStack patches. For more information about IBM PowerKVM refer to the Redbook .
