Highlights for Linux on POWER
There's a lot of interesting projects going on with the Linux on POWER and OpenPower initiatives this year and into next year. But first, a brief introduction of myself..
My name is David A. Desrosiers (no, not THAT David Desrosiers, make sure you use the "A." in the middle if you Google me), and I've been working with Linux and Open Source since 1992/1993 and AIX before that. Several years ago, I used to work for Linuxcare in their Research group with some brilliant and very well-known Open Source developers. Now, several years later, I work for IBM with the title of "Linux on POWER Developer Program Manager".
I'm also the maintainer of a few embedded projects you might know about. pilot-link is probably the most well-known out there. Its the glue between your PalmOS handheld and your PIM data. Lots of projects rely upon the code in pilot-link to function.
Plucker is another one I contribute to heavily (as well as hosting and designing the website, cvs and other facilities). There are 9 of us in the core team, distributed worldwide.
Developing in very constrained environments such as handhelds and PDAs is a stark contrast to developing on something as vast and "virtual" as POWER.
My focus within IBM is to help bridge the gap between the Open Source development community and the IBM development process. Some of my tasks include helping to provide remote access to POWER-based hardware for developers (and budding developers) to use to learn, test, debug and develop new or existing applications on the POWER platform. There are some subtle differences and having access to real hardware is important. I'll go into some detail on that a bit later...
If you're interested in checking out what the POWER systems actually feel like under the hood, you can log in remotely to one of the University systems we've set up at the University of Augsburg and Peking University. Create an account, pull over some source code from your favorite projects and try building and testing it under the POWER architecture. Each server offers its own configuration and options with your remote (non-root) shell account.
University of Augsburg, in Augsburg Germany (Debian Testing/Unstable)
Peking University, Peking China (SuSE 9.1)
There's quite a few other things going on that I'll elaborate on later. I'm doing my best to learn as much as I can about the POWER architecture (its new to me too!), and splitting my duties between being an interpretor for the Open Source community and for IBM as well. Its all great fun
Feel free to comment or ask me any questions you might have about how you can get involved, and I'll do what I can to get you the answer, or point you to the right people who can get you the answer.
Interesting times are ahead..!
Did you see that on Nov 17th Oracle announced the availability of Oracle Database 10.2 for Linux on POWER?
They announced support for the Enterprise and Standard Edition of Oracle DB.
Now application developers and customers can use scalable applications that utilize Oracle DB, and still take advantage of the capabilities of POWER5 based servers. This includes full application 64-bit implementations, Advanced POWER Virtualization with micro-partitioning, and the Virtual I/O Server. Using APV and VIOS, you can consolidate a firewall server, Web server, application server, and database server into one POWER5 system. This can even be done on a small System p5 or OpenPower server!
Oracle also announced the availability of Oracle Database 10g Client Release 2 and Oracle Clusterware Release 2.
Oracle Clusterware can be used when creating a Linux cluster solution. Linux clusters are becoming popular as a method to provide a high-performance, low-cost data warehousing solution.
Information on this announcement, including some of the features and advantages, can be found in the awareness white paper:
Oracle Database 10g Release 2 for Linux on POWER - Awareness document
(click on the Full text white paper - View Arcobat link)
Oracle provides downloads at the Oracle Database 10g Downloads Web site:
Select Oracle Database 10g Release 2 (10.2.0.1.0) for Linux on Power New! (17-Nov-05)
This will give you access to downloads for the following:

Seems there is a website with the Top 25 reasons for choosing Linux (http://www.bellevuelinux.org/reasons_to_convert.html)
Take a look. I think there is overemphasis on the "no cost" which is not really true in most enterprise environments. If you get it free from the kernel.org site, it is free but it is not a total os. But, places like Debian do provide a "free" version of an OS but usages is lower than RH and SUSE.
but anyway...I think a missing point is the ability to be consistent within an enterprise so you have consistent procedures, levels, security, etc. and you can match it to the platform that best matches the applicaiton need.
what do you all think the top reason why you choose Linux?[Read More]
As you are probably aware, IBM spends a lot of time and money on working with our commerical software partners. What many people do not realize is there is a lot of energy put into finding ways to better support and foster a self-sustaining Open Source developer community for Linux on POWER.
BTW - "Linux on POWER" is an umbrella marketing term used w/in IBM to cover Linux running on a number of PowerPC and POWER-based systems, spanning embedded to the largest POWER5-based servers. I tend to think of Linux across the broader range processors from IBM and our competitors as LinuxPPC or LinuxPPC64. That seems to be more broadly understood in the community.
Some of the ongoing community programs include...
As mentioned in an earlier post, we are working w/ Universities world-wide to enable them to contribute and engage more with the development community by hosting POWER5-based servers available to anyone that wants to use them for Open Source Projects that meet the Universities acceptable use policy. The Open Source Development Lab also has 3 OpenPOower 720, so be sure to ask to be able to use those when working there.
We have run a couple of contests now. These have generated a lot of interest and provided a resaon for developers to get hands on experience w/ LinuxPPC. For those interested enough to successfully port specific applications, they have been awarded w/ PowerPC-based workstations and other prizes with which they can continue to exlore LinuxPPC. And yes, the contests have had some warts, but we try to make them as interesting as possible.
A number of the more popular community distributions are now providing support for POWER5 including Gentoo and Debian with others to follow through collaberative work IBM has done with them. Gentoo is now hosting their entire CVS tree on an OpenPower system.
IBM has worked closely w/ internal and external technical content providers to supply high quality and and easy access to the kinds of information developers need. there is a lot of good quality information on developerWorks and another one of my favorite sites is PenguinPPC.org.
These are a few of the programs focusing IBMs attention on the LinuxPPC development community. As the strategist trying to develop these programs, I am always listening for and trying to generate new ideas/ways for us to get involved. If you have any, I'd love to hear them.[Read More]
We all know that Linux is a cool operating system, open, sometimes free (yea right!) and is rapidly growing acceptance. With the 2.6 kernel, the ability Linux to support workload with higher requirements (performance, reliability, security, etc) is now a reality. There are several Linux Distributors "shipping" the 2.6 kernel such as RedHat, Novell SUSE, Debian, etc. One might think that these distributions are all the same but upon closer inspection we can see the kernel is made up of architectual specific code to exploit certain server families. The API of the OS is the same so the ability for applications to run on the various architectures is preserved (as long as you compile the application to the proper instruction set and have the proper run time library support and device drivers). So is it all the same then? I think the answer is a resounding NO. It seems these architectual specific nuances can lead to very dramatic differences in application performance and reliability and sometimes even the ability to run at all.
When the Linux Distributors create a distribution, the major ones today tend to implement a common build process. This is good and if I were them I would do the same. However this may lead to differences and non-optimal execution of programs if you wish to run the application on different architectures. Consider one point only: I/O buffer sizes. If there were a popular architecture that shared memory and I/O over a single bus, I would choose a buffer size that would allow the minimal I/O "interference" with memory access. This usually would mean a relatively small size. If I were then to compile the Linux Kernel for a differnet architecture using the same "defaults", but where the "other" architecture had a separate I/O "bus" and memory "bus", it would not be optimized to the architecture. At least with either a recompile of the kernel or a change to the run time environment, I could move the "standard distribution" to a higher performing version by simply changing the I/O buffer size default. Upon inspection there are several instances where the default build parameters for one architecture will not be optimal on another architecture.
This is just one of several examples of where Linux is Linux is Linux, but it is not the same. In future discussions I will go into more details on these and the relative impact of them....and if you want to get a little more performane out of your Linux Kernel, take a look and see how many print daemons exist for printers you do you run....if you turn them off, you will get a little more performance. I wonder why all these print daemons are really in there anyway?[Read More]
In an article by Phil Hockmuth, he reports that Microsoft commissioned a survey that showed that Linux required 68% more maintenance time then Windows. Wow! what a suprise!!
(elsewhere, a survey said that opensource developers claim they can fix any security bug in less than 8 hours).
I love surveys. Especially ones that show results favoring the commissioning body. Phil, I love, apparently agrees and says "Don't pay too much
attention to industry surveys; do your own lab evaluations,
tests and pilot deployments, and see for yourself what works best" and "should be taken with a unit of sodium as large as a farm animal's salt lick."
Apparently Redhad and Novell agree.
We all know that email is now becoming the peanut butter that is gumming us all to a stop. I wonder how much productivity is lost in companies the create FUD and force others to respond.
Maybe there should be a law..oh I take that back since now the government might get involved. argh...[Read More]
Linux on POWER is fully supported by the IBM Advanced Power Virtualization capabilities….depending on a few things.
First you have to be running Novell SUSE SLES 9 or RedHat AS 4 to be enabled for all the virtualization capabilities on POWER. This includes LPARs, DLPARs, V I/O, VLAN, and micro partitioning and shared pools. What does not work, and this is not a limitation of Linux on POWER, but rather a limitation of LINUX 2.6 kernel: Dynamic memory (you can re assign memory to a partition, but it must be rebooted before the memory change is recognized) and Partition Load Manager (this requires hooks in Linux which do not exist yet…..) Other than that, the 2.6 kernel is fully enabled to support the full virtualization..and you can also be running AIX (or on selected models, iOS also).
Now if you choose to run the 2.4 kernel of Linux, it has less functional support of Advanced POWER Virtualization since it is missing the pre-emptive capabilies of 2.6. This means you loose the ability to run dynamic device add/delete (as in disk adapters) and you also loose DLPAR since these obviously need a stop/restart capability in the kernel. Other items of the 2.4 kernel are supported such as LPAR, VLAN, micro partitioning, shared pools…and although not related, also SMT (but that is a different story).
Remember that on the POWER5 systems you can only boot SLES 9 (hence the 2.6 kernel) and RH AS 3 (with limitations above since it is not a preemptive kernel but even though it is 2.4, certain functionality of 2.6 was back ported..such as SMT support), and RH AS 4. Cool…
Now Xen…well it is currently not under development nor test nor porting for POWER. So it appears to be an x86 only application at this time. It is fully capable of being POWER enabled, but the plan does not exist yet for the possible code changes, testing, and etc. Some argue that this is not needed since we have Advanced POWER Virtualization which will have far greater capabilities than Xen for quite a while. But Xen is free, but limited, and APV costs a little. Interesting…less filling costs less, versus, more filling costs more. What do you think we should do with Xen on POWER? Push for availability since it will drive up virtualization of Linux on POWER or continue with the APV plan (which we will do anyway..)?

Very nice new results posted this month using the latest SLES 11 enterprise operating system running on a 64-core IBM Power 595 system. Ideas International helps keep track of the overall Top 10 lists for workloads like SPECint_rate2006 and SPECfp_rate2006.
For "fp" workloads, the SLES 11 result is the #2 result of the overall SPECfp_rate2006 "peak" results published.
For "int" workloads, the SLES 11 result is the #5 result of the overall SPECint_rate2006 "peak" results published.
These results are based on an IBM Power 595, POWER6, 5.0GHz, 64 cores (32 chips, 2 cores/chip, 2 threads/core), 512GB Memory, demonstrating superior scalability that comes with SLES 11.
Links to the published files:
Based on published results as of 4/14/09.
SPEC results source http://www.spec.org. See http://www.spec.org/spec/trademarks.html
Novell has officially released the latest SUSE Linux Enterprise version of their SLES operating system product, which for the Linux on Power team is the culmination of months of focused efforts and improvements.
Many of the key features being introduced or updated with SLES 11 will be described in more detail in the coming weeks over on the DeveloperWorks wiki pages:
Several of us work on performance so we are particularly interested in scalability and performance. The Linux on Power support in SLES 11 includes features like an improved scheduler, 64KB page support, a significantly updated Linux kernel base, improved HPC clustering and Infiniband support, newer version gcc and glibc, and more. Of course, there's much more to the operating system than just performance enhancements, check out the Novell web sites for more information![Read More]
One system. Half a Teraflop. Linux.
Recently the IBM Linux Performance team submitted a LINPACK HPC result of 500 GFlops (half a teraflops!) on a single IBM Power 575 compute node. These water-cooled systems pack significant compute power and memory into a dense form factor.
This result was produced using the 32 4.7GHz POWER6 cores with 128 GB DDR2 533 MHz of memory and the latest RHEL 5.2. Other software includes IBM XL Fortran V11.1 & IBM XL C/C++ V9.0 for Linux Compilers, IBM Engineering Scientific Subroutine Library (ESSL) V188.8.131.52 for Linux on Power, libhugetlbfs v1.0.1 (transparent 16MB large pages) and Open MPI 1.2.5. Compared to non-super computing systems, this was the best result published on a 32 core system as of May 30, 2008, impressive for a dense 2U form factor.
With the introduction of 64KB memory page size support for the Power processors in RHEL 5, applications benefiting from larger page sizes now realize significant performance gains right out of the box. See 64KB pages on Linux for an introduction on how Linux leverages the alternative page sizes provided by the POWER hardware. As usual, performance gains obtained are dependent on the application, software used, and tunings leveraged.
Top 500.org and LINPACK
LINPACK has been a highly respected and utilized benchmark metric for more than 20 years. It was developed to target highly vectorized supercomputers. The following is the description of the LINPACK benchmark from http://www.netlib.org/linpack.
The Rpeak of the IBM Power 575 4.7GHz is 602 GFlops, which is the theoretical limit the system can achieve. The Rpeak is calculated by taking the number of cores times the CPU frequency times the number of floating point operations/second. In this case, 32 * 4.7 * 4 = 601.6. At 500GFlops, this combination of RHEL 5.2 and other software on the IBM Power 575 system achieved an impressive 83% performance of the systems maximum capability.
A complete listing of published LINPACK results can be found at http://www.netlib.org/benchmark/performance.pdf.

Linux on PPC Community News... Robert MacFarlan
While PPC-based game consoles and eval boards abound, there hasn't been much thought given to a PPC-based Linux developer optimized platform since Apple bailed on PPC, until now. Terra Soft Solutions are offering a 2.5GHz PPC97MP-based development platform dubbed YDL Powerstation featuring four cores, Open Source firmware which in theory also provides access to Open Source virtualization technologies on PPC, Open Source graphics drivers, Open Source operating system and even the chassis is easy to open. :-) I am told the system is incredibly quiet which is also a bit of a strange twist for a Power compatible system with a price point of less than two grand. I can't wait to get one.
You know you've hit geek'ish mainstream when you are featured in Popular Mechanics. This months magazine features an article of how to install and boot Linux on a PS3 - "Turn Your PS3 into a Computer". They also have an article - "How the PS3 Helped Build the World's Fastest Supercomputer" referring to IBM provided "Roadrunner" hybrid AMD and Cell Broadband Engine cluster delivered to Los Alamos National Lab. Doesn't get much more mainstream than that!
Community work on PPC has continued as well. A fair number of the major community-based distributions have continued or added support for PPC. Some support levels have changed a bit, but it continues to be the 3rd major architecture receiving support from the likes of Debian, Fedora, OpenSuSE, Gentoo, Slackware and even after all of the controversy, Ubuntu still carries "community supported" PPC and PS3 images for their latest releases. Last I checked CentOS was adding 64-bit support for PPC as well.
Key Open Source projects that have historically been a gap for PPC have released support in the last year or so - some examples include Gnash, OpenVZ, ffmpeg, LSB testing suite, to name just a few.
So my friends, while Linux on PPC may have seemed to have gone quiet, there has actually been a lot going on and people continue to innovate.[Read More]

Whew. Over two years have flown by since anyone has posted here.
Recently several of us got together and decided it was high time we got this blog active again.
Linux continues to mature at an amazing rate and the world of Power continues to grow and expand. Since the last posts back in 2006, Red Hat has shipped RHEL 5, which is already on its second update. Novell has shipped SLES 10, which is also already on its second update. Underlying it all is the rollout of Power based systems and solutions.
So what's new? Here's some example obvious pieces.
On the Linux side...
Brian Warner has started a Planet LTC web site which consolidates various public bloggings from LTC Linux advocates across a gamut of topics. Good regular reading.
Here on this LinuxOnPower blog we'll try to stay on top of things happening in the marketplace which people might be interested in. There are a lot of good things continuing to flow from the Linux community, customers and software vendors, and the POWER hardware and solution teams around the world.
IBM POWER6 is out and is featured across the IBM Power system products. Today many of us are working on Linux running on the new IBM Power 575 system, a sweet water-cooled technology base designed for clusters, and the IBM Power 595 system, which supports up to 64 cores and all of the technology advances inherent in the POWER6 technology base.
My focus these days is on Linux Performance and I'll be highlighting performance, scalability, HPC, energy/performance trade-offs, and other related topics. In particular, there's some cool things emerging from a strong focus on the HPC front, some examples are covered in a recent article seen on HPCwire. Check it out.

Hey there - Did you read about Open Invention Network? Check this out on CNN: http://money.cnn.com/2005/11/10/technology/linux.reut/index.htm
IBM has partnered with Sony, Phillips Red Hat and Novell to create Open Invention Network. (OIN) Quoting the article linked above, "If OIN's approach to managing intellectual property wins acceptance, it could overcome a big stumbling block to wider corporate adoption of Linux and pose challenges for major opponent Microsoft Corp. (Research), which has argued that relying on "open source" software poses legal risks."
Ok, so not so sure that there is a stumbling block to corporate adoption of Linux - you have seen the growth rates but clearly this is another step of broadening the market for Linux.
Hope you are enjoying the beautiful fall weather and note that more change is in the air! Stay tuned!

Long time, no blog. Yes, I'm guilty. I admit it. I've been hunkering down, focusing on some project work, ramping up for the new year and trying to focus on coming up with some creative new initiatives.
I spent a few days down in Austin, TX meeting some of my remote colleagues face-to-face. Robert, Hayden, Tiffany, Helen, Kathy and others. I had a great time overall. It was great to see the IBM campus, get lost on Loop 1 several times, meet people I've only seen in email, and accomplish much more in-person than we could have ever done through email or phone calls. Put everyone in the room, lock the door, and let the brains and neurons heat up.
To summarize Austin in a few sentences:
1.) LOTS of driving, loooooong commutes
2.) Mediocre food and restaurants (but I didn't explore much)
3.) Very friendly people in every corner of the city
4.) Great weather all around! What? No snow?!
I'm from the Northeast, we invented bad weather, bad driving, bad attitudes and bad spending habits. Austin was a breath of fresh air, literally and figuratively.
As for the new initiatives, I can't tell you what they all are yet, but they will be really interesting and engaging for everyone in the community; developers, users and other supporters. We're still building that "Linux on POWER Ecosystem" I've mentioned previously, and putting a lot of resources behind it to keep it "moving forward". We believe in it, and we're committed to it.
As Helen mentioned, there's a new'ish portal open now for public use at OpenPowerProject, which has lots of links to resources and access to remote machines you can use to test-drive PowerPC/POWER architecture. There are a few new universities coming online along with the two pillars that have been there since the beginning; Augsburg and Peking. University of Portland is also online and we're working on at least two more in Russia and India.
There's also quite a few new public events happening out in the community: OLS, linux.conf.au, Linux Kongress and others. We're trying to see what we can do (budget allowing, of course) to help support the community at these events, through either face-to-face meetings, BoFs, or outright presentations. If you've got any ideas we haven't thought of, throw them my way (firstname.lastname@example.org).
The other initiative that's getting off the ground, is the Linux on POWER Advisory Council. This has been a bit slow to get moving, and the legal entanglements aren't speeding things up, but it looks like all of the proposed candidates have accepted and are routing their paperwork back to us so we can get started.
The purpose of the "LoPAC" as I affectionately call it, is to help us oversee the various materials, collateral and initiatives we're targeting to deliver or publish in the community to make sure we're conveying the right message.
There's a lot more to it that I can't go into, but you can be sure we're taking their ideas, and the suggestions of the broader community, to heart. Each candidate represents a country of interest, including the US, Uk, Germany, Japan and Brazil. We may add additional countries and members if the need grows, but this should work for now. Baby steps.
The holidays are upon us, and that means working double-time to get things done, closed-off, signed-off, and in-progress before the new year begins. 2006 promises to be a very "interesting" (and I say that lightly) year with IBM, Linux, technology in general, and the rest of our friends and competition.

Did you see that Redhat said that with the emphasis on XEN work, they MAY also move to a model where you do not get charged per instance. That's good...and what Novell SUSE is doing now. This could close a sore point for RH users.
But remember, you could probably always make a volume agreement with Redhat..but what if you were a small company, 1 server and want to run 4 partitions. This could save you money! Unless you are in Europe where there is alreay a 10 -1 promotion for Redhat Linux. URL for promo:

Wow...some people drink funny stuff...or are starting to do reporting like CNN. So at http://www.computerworld.com/softwaretopics/os/story/0,10801,105786,00.html?source=NLT_ES&nid=105786
SUN is more open and more of an OS than Linux. The argument is that Open Solaris is an OLD OS that is only made with one stem. On the otherhand, Linux has lots of distributors and they create the Linux DISTRIBUTION differently and hence create all different version so Linux OS. Wow...The linux kernel has the same root in all of the various distributions and the flexibility lets people use and build what they want. Now you are saying that is bad...funny, ISVs can write to the same API and get the same functionality, users have choice of which distribution to use and there are THOUSANDS of contributors to advance the kernel and surrounding suppport code.
Open Solaris (yeah right!) has how many people contributing? and I bet the whole opensource community is dropping support for Linux and moving to extend Solaris. And I am sure you can just compile Solaris is the GCC compilers to run on any platform..and I bet Redhat and Novell will soon create Open Solaris distributions and provide support for them...and Open Solaris will integrate XEN and have all device drivers you want...
Yeah that's it...that's a leg up.[Read More]

"The p5 servers have already delivered benchmark performance more than double that of HP Itanium II-based servers and as much as three times the performance of HP PA-RISC and Sun UltraSparc-based systems." Oh yeah!
In addition to the performance we have virtualization. For anyone who doesn't know about virtualization - it allows you to run multiple operating systems per processor. This will enable you to replace several smaller servers (even running differant OS) on one more powerful, higher performing server. Efficiencies that benefit you as an IT manager, that's a novel concept, huh?
Now, about Linux....yes that is my focus. So now we have systems for many workloads. We have Linux based systems to support your infrastructure with workload solutions for file and print, web serving and more. We have application based Linux servers for DB2, Websphere and even Sybase. High performance computing on Linux is a growing focus with solutions in Bioinformatics, Proteomics and Computational Chemistry. Check out these solutions: http://www-03.ibm.com/systems/linux/power/solutions/index.html
Yahoo - more products supporting Linux to meet your growing demand!

Did you see that Novell made a great step forward by offering a license and single price for all the Blades in an IBM BladeCenter chasis. This is a tremendous possible saving for customers with bladecenters. Regardless of blade type, POWER, intell, etc, a single license charge supports the full population. Not to try and sell you on anything...but check it out if you have a bladecenter..you might save up to $17,000 for your company.

Did you happen to catch the latest interview with Linus Torvalds? Very interesting....talks about enforceing trademarks of Linux which he owns. He says this is nothing new from his standpoint. Also comments (although he ducks saying he will leave this to the lawyers) on a possible re-write of the GPL...

If you look at the Novell site http://www.novell.com/products/linuxenterpriseserver/powerpromo.html
it tries to tell you that SUSE is better the RH for Linux on POWER...why? Price and licensing. That is kind of true for sure, but is not why it is better for POWER..unless you think Price is the main driver. Also on the site is a paper by an analyst that is also kind of high level and content free.
Isn;t it about time that someone just points out that the base kernel is the same but there are differences like RAS support, default performance setting (for those who never bother to change the defaults and run slower than they can), admin tools, maintenacne techniques, switching costs,and support! These should be explained in a table with RH and SUSE as the columns..then we would have something.
.....and I might just do that..but the lawyers would go nutz and RH and SUSE would claim foul...wonder what we should do to get a valid comparison??
