At the KVM Forum 2013...
Paul Mackerras provided some technical insights into what's going on with POWER8, KVM support, the OpenStack project with nested virtualization considerations, Guest PCI hotplug primarily for virtio devices, hardware error detection and recovery, and answering various questions.
This is a technical forum.. not a product discussion, so you get a good sense of the technology investments continuing around Power systems and Linux.
Paul's 30 minute talk is available on youtube from the KVM Forum... [More]
Linux on Power for ISVs Technical Symposium

Everyone remembers Cheers , the 1980s television sitcom that included the well-dressed, but slightly funny looking Norm who always entered the bar as everyone called out "Norm!" I suspect that most of us can remember several lines from the theme song, "...Where everybody knows your name, And they're always glad you came..." But, If you can't remember the them, I know that ALL of us who watched the show want to be Norm and have our name called out as we enter the room.

Several IBM SDK for PowerLinux videos were recently published in the PowerLinux YouTube channel . The IBM Software Development Kit for PowerLinux is a free, Eclipse-based Integrated Development Environment (IDE) that integrates C/C++ source development with the IBM Advance Toolchain for PowerLinux, Post-Link Optimization, and classic Linux performance analysis tools, including Oprofile, Perf, and Valgrind.
Here are the links to the specific videos:

One of the interesting discussions going on right now across some of the teams around Linux and Power systems is around the ability to trace what's happening in the kernel and across the operating system.
The reasons are many... what's going on in the network stack? where are unexpected delays (latencies) happening around high speed transactions? where can we optimize the operating system better? is the behavior of the OS really doing what we think it's designed to do? etc etc etc
By: Ralph Nissler. IBM is putting its money (US$1 billion to be exact) where its mouth is (if you don't yet know what I'm talking about, check out the ZDNet article ) and as part of that, has recently launched the dedicated Power Systems Linux centers.
Currently, there are four in Beijing, Austin, New York, and Montpellier, France. They're there to provide training on programming, porting and optimizing Linux on Power Systems, with porting/optimizing probably being the big hitters. Especially for those porting from... [More]
By: Neli Momtaheni. Have you ever gotten the memram error during a Linux installation? Several factors can cause this error, but often it is related to the operating system you previously had installed on your server or logical partition. Based on my experience, I get this error when I try to install Linux on a server that had been running the AIX OS. To correct this error and move on with your installation, simply issue the following commands.
The boot process resumes,... [More]
Many technical advances continue in the realm of classic compiler choices for Linux and for POWER systems.
In the open-source community, the gcc.gnu.org community continues to drive technology improvements into the gcc, g++, and gfortran compilers. GCC 4.8 has recently been announced and is available for use across many industry platforms.
With IBM's assistance on POWER systems, the latest GCC compilers can provide outstanding performance on the latest POWER systems, including POWER7, POWER7+, and... [More]
