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]

Exciting times for Linux and for POWER.
Earlier in the week, a new POWER and Linux consortium was announced - the OpenPOWER consortium. IBM's Tom Rosamila posted his views on the SmarterPlanet blog .
Open and Collaborative Development is the Future of Open Computing
(I added some bold emphasis in the clipped pieces below - see the blog post for more of the details)
Under the OpenPOWER initiative, IBM will license the core intellectual property for our POWER... [More]
At the Red Hat Summit this week, in one of the opening keynote presentations, Arvind Krishna (the IBM General Manager for Development and Manufacturing in the IBM Systems & Technology Group), presented a good summary and strategic view of IBM's continuing contributions to open-source communities, technologies, and customer solutions.
The video of his presentation is available here
Near the end of the video (right before the 23:00 mark), Arvind makes two announcements which help demonstrate the continuing excitement and... [More]
Over on Google+ , Jeff Scheel pointed out how easy it is to get access to a partition for PowerLinux testing in the Open Source Lab at Oregon State University (OSU). Check it out!
Jeff followed that post with another open question for community developers and projects that may need a PowerLinux loaner. If the OSU lab doesn't fulfill what you are looking for, you might ask Jeff to consider a loaner for your project. Follow-up over on Google+ if you are interested.

PowerLinux is Linux, one of several hardware platforms that Linux supports. Other Linux platforms include S390, ARM, Intel IA32 and x86_64, and a wide variety of the special purpose or embedded use processors.
When I work with customers and independent software developers, this concept of being the same (Linux is Linux) and simultaneously different (platform) can be confusing. Some want to be reassured that PowerLinux is “standard Linux”; to that, the short emphatic answer is yes .... [More]
In the category of learning something new on a regular basis, over the last week I discovered some commands on Linux running on Power systems which were new to me. Turns out "lparstat" has been implemented, and a colleague here in the LTC pointed out two commands "lscpu" and "lsblk" which I hadn't seen before.
Trying these out on a system with POWER7,
# cat /etc/*release*
SUSE Linux Enterprise Server 11 (ppc64)
VERSION = 11
PATCHLEVEL = 2
# rpm -qf `which... [More]
Over in the openSUSE realm, the "Open Build Service" (OBS) recently was updated with new IBM PowerLinux 7R2 servers. A recent news update was posted on news.opensuse.org .
"To ensure continued Power and Linux compatibility going forward, IBM and SUSE recently partnered to add more build capability to the openSUSE Build Service. The openSUSE Build Service is a service which offers an automatic, consistent, and reproducible way to build and distribute Linux packages from source code to multiple... [More]
By: Kersten Richter. In the PowerLinux world where the installation choices are seemingly endless, a clear path for installing Linux on a PowerLinux server can be somewhat difficult to find. In late January, Steve Champagne and I (Kersten Richter) traveled to Rochester, Minnesota for our own installation experience. We received an IBM PowerLinux 7R2 (8246-L2C) still in the shipping box. We spent several days exploring various installation scenarios and, based on our experiences, have recently published several resources to use for... [More]
By Rafael Folco From the Linux Technology Center, a team focused on Power I/O Performance just released a performance report with recommendations and basic performance characteristics of the ConnectX EN 10GbE adapter for Power Systems servers running Linux. This adapter is a popular and common dual-port 10Gb Ethernet adapter for IBM's Power systems. The report covers the basic features of the adapter and driver, provides some example performance results with suggestions on how to validate the results yourself with a workload called... [More]
By Jenifer Hopper. On POWER7+ systems, a new processor chip packaging scheme has emerged which combines two processor chips into a single module, which in turn plugs into a single socket on the system. Along those lines, a n ew article on POWER7+ SCM and DCM Systems has been published. IBM® recently announced new updates for the IBM Power 750 Express server and the IBM Power 760 server, both of which are now based on the newly introduced POWER7+™ processor packaged on a dual chip module (DCM). Earlier POWER7® systems were based on... [More]

I've just released a white paper with some info on using the encryption and random number generation hardware accelerators in the POWER7+ CPU in Fedora Linux. It covers a few areas:
1. Background on the hardware and software architecture
2. Setting up Fedora to use the accelerators for disk encryption and IPSec
3. How to monitor that you're really getting hardware acceleration
Hope you find it useful, and don't hesitate to send me questions or... [More]
