There’s been some work on porting FreeBSD over to run natively on top of OPAL, that is, on bare metal OpenPower machines (not just under KVM). This is one of four possible things to run natively on an OPAL system: Linux hello_world (in skiboot tree)…

A second STAC benchmark on #PowerLinux , this time the A2 (http://bit.ly/1Moafo5).

Perhaps instead of people asking me "why use Linux on Power?", I need to start asking, "why NOT use Linux on Power?"
Newly published STAC-A2 benchmarks show POWER8 outperforming x86 servers on standard financial industry workloads.

Are you looking for access to +IBM Power Systems to use to port your opensource project?  Have you tried our labs at Oregon State University in the U.S. or UNICAMP in Brazil but find the access to have too much latency?

If so, perhaps the new OpenPOWER HUB in Brno, CZ would meet your needs.  This is the 3rd lab WW to provide free access to opensource developers who want to port their applications to #PowerLinux .  It's a collaboration with +Redhat and Brno University of Technology.
Red Hat in the Czech republic, Faculty of Information Technology at the Brno University of Technology and IBM Linux Technology Center have partnered to provide access to POWER based servers to enable an open platform for innovation to the open source community.

I missed this article in late April from The Platform. 

Gotta love the quote from Urs Hölzle, Senior Vice President of the Technical Infrastructure Team: "People ask me if we would switch to Power, and the answer is absolutely,”

I also appreciate the explanation of how little endian helped them.

Can #PowerLinux help you?
For most companies in most industries, riding down the Moore's Law curve to get more compute power for the same money is good enough. But for the few dozen

+IBM participation in +OpenStack, especially in the area of #KVM on #POWER8 is an area which frequently comes up with technical customers.  It's a little known "secret" that IBM has a Continuous Integration (CI) system on Power that runs OpenStack tests.  It's an ongoing project that started over a year ago focused on Nova, but continues to evolve with more components all the time.

If you 'd like to engage, or simply know more, feel free to check out the project link below...
Overview. This is the IBM PowerKVM CI status page. For questions and more information, please contact kvmpower@linux.vnet.ibm.com. You can also ping rfolco or mmedvede on OpenStack IRC channels @Freenode. PowerKVM CI currently runs Openstack Icehouse release. Devstack-gate jobs run Fedora 20 as ...

In the last 2 days I've found 2 new cloud images for Power:
http://download.cirros-cloud.net/0.3.4/ ; and
http://ppc.koji.fedoraproject.org/compose/22_TC2/22_TC2/Cloud_Images/

Nice to have options!

Thanks for posting, +Tony Breeds!  The first images look suspiciously "old" due to the name of "powerpc".  I worry they are from the old Mac ecosystem.

However, the Fedora images indeed are part of our ecosystem efforts.  We're trying to get groups like Fedora who are doing cloud image builds to include Power as part of their builds.

I WHOLE heartedly agree that options are good.  That's what Linux is about -- CHOICE!

For those of you who don't like formal IBM press releases, here's a write-up on +SAP HANA on #PowerLinux that's alot more consumable from +eWEEK.com.

Personally, I like the Charles King quote as it's matches what I've been saying: IBM Power hardware architecture is perfect for thread hungry workloads.  Linux is just the enabler, it's really about the hardware and the application.

SAP HANA + POWER is a perfect pair.

Back in about 2010, I was working on a highly custom supercomputer research project with about 2.2 million cores called Cyclops64. It was a joint project between the University of Delaware, IBM and the NSA. It was interesting in a lot of respects, but what its most unusual feature was its networking.

Anyone interested in code coverage for OpenPower firmware? Well, we are :)
 
For skiboot (which provides the OPAL boot and runtime firmware for OpenPower machines), I’ve been pretty interested at getting some automated code coverage data for booting on real hardware (as well as in a simulator). Why? Well, it’s useful to see that…

Do you know if IBM employees (working in their own time) are eligible to receive the bounty?

Checkout the great work by +Dinar Valeev from +SUSE on Power!
 
+openSUSE Tumbleweed for #powerlinux is tested by #openQA I'm hacking on to add PowerVM and PowerNV platforms + CPU/Mem/PCI hotplug tests
openQA is a testing framework mainly for distributions

Some of the crazy grads at +OzLabs started a POWER technical blog called: Store Half Byte-Reversed Indexed. +Daniel Axtens wrote a great post on CAPI with some nice analogies.
(I wrote this blog post a couple of months ago, but it’s still quite relevant.) Hi, I’m Daniel! I work in OzLabs, part of IBM’s …

Great blog post by Richard Jones about his work on virt-builder.

I contemplated correcting his statement about pricing of Power servers, but I'm fighting a perception issue that's hard to battle.  Folks really need to price an S812L or S822L server for themselves.  Telling them that they start around $10k list price just seems too good to be true...
