Ubuntu released OpenJDK 7 packages based on IcedTea 2.5.0 (ie. JIT enabled for PPC64 and PPC64LE). Many thanks to Matthias Klose. ^_^

As of now they are being build for Ubuntu 14.10 only - on Ubuntu 14.04 they have to be downloaded and installed manually (tested and working with Ubuntu 14.04 dependencies).

For a minimum JRE environment the following two DEB packages are needed:
http://launchpadlibrarian.net/179468194/openjdk-7-jre-headless_7u60-2.5.0-1ubuntu3_ppc64el.deb http://launchpadlibrarian.net/179468195/openjdk-7-jre_7u60-2.5.0-1ubuntu3_ppc64el.deb

For a SDK environment also install:
http://launchpadlibrarian.net/179468193/openjdk-7-jdk_7u60-2.5.0-1ubuntu3_ppc64el.deb

Or simply run:
$ wget http://launchpadlibrarian.net/179468194/openjdk-7-jre-headless_7u60-2.5.0-1ubuntu3_ppc64el.deb http://launchpadlibrarian.net/179468195/openjdk-7-jre_7u60-2.5.0-1ubuntu3_ppc64el.deb http://launchpadlibrarian.net/179468193/openjdk-7-jdk_7u60-2.5.0-1ubuntu3_ppc64el.deb


$ sudo dpkg -i openjdk-7-jre*.deb

If the above links do not work they might have released newer binaries, look for them at (top items in the "Publishing history", the link is at the "version" column):
https://launchpad.net/ubuntu/utopic/ppc64el/openjdk-7-jre-headless
https://launchpad.net/ubuntu/utopic/ppc64el/openjdk-7-jre
https://launchpad.net/ubuntu/utopic/ppc64el/openjdk-7-jdk

Please let me know if you have any troubles or need additional help
getting those to work. Enjoy!

Matthias Klose has now backported JDK7 and JDK8 to Trusty (Ubuntu 14.04) as well. You can get those from this PPA: https://launchpad.net/~openjdk-r/+archive/ubuntu/ppa

Or simply run:

$ sudo add-apt-repository ppa:openjdk-r/ppa

Is this a reaction from Intel on the #OpenPOWER announcement by us?   Hmmm....
Summary: To ensure that ARM or other alternative architectures don’t gain ground in the data center, Intel is launching a customizable chip that marries its Xeon CPUs with an FPGA.

IcedTea 2.5.0 has been released!

This release brings JIT support to PPC64 and PPC64LE - we are talking about 30-100+ times improvements on compilation and runtime speeds compared to Zero (interpreted mode only) . Now it's up to your preferred GNU/Linux distro to pick up the new release. Hopefully we will be seeing it being packaged by distros in the upcoming weeks.

Kudos to Andrew Hughes for coming up with such cool version name: "POWER to the People!" He nailed it!

+Dinar Valeev I asked at the ppc-aix-port-dev mailing list and they answered that the ppc port currently uses the c++ interpreter - for which there's no support for class data sharing. The template interpreter does have it and they are working on it. See http://mail.openjdk.java.net/pipermail/ppc-aix-port-dev/2014-June/002029.html

A nice overview of both C++ and Template interpreters is available at https://today.java.net/pub/a/today/2009/05/21/zero-and-shark-openjdk-port.html#the-interpreter

Those of you looking for more technical information on #PowerKVM from IBM, here is the link to draft Redbook.  Our very own +Dinar Valeev from +SUSE, and +Breno Leitao from #PowerLinux community have been participants in this book.  Nice work, gentlemen!

Hot off the presses:  "SAP and IBM continue to collaborate closely with the intent to enable SAP HANA to run on the IBM Power technology, including POWER7+ and the newly introduced POWER8 system on Linux. The companies ultimately aim to benefit customers that run their mission-critical SAP applications on IBM Power Systems. SAP and IBM today announced a limited test and evaluation program for SAP HANA on IBM Power Systems, allowing selected customers to test SAP HANA on IBM POWER Systems with Suse Linux, leveraging existing IT infrastructure investments while driving innovation using technologies such as SAP HANA...."

All on Linux on POWER. Tested on POWER8.
 
I just posted my patch for MySQL 5.6 to work on POWER (including POWER8) and the tale of what I had to do to make it work correctly and well.

Had the pleasure of talking about #OpenPOWER Foundation at #LinuxCon Japan, last week in Tokyo.  Lots of interest and good questions.

Everywhere I went with the IBM Team, everyone wanted to know more about the foundation.  I can't tell if it's the "Google mystic" or if something else is exciting people.

Regardless, I shared the slides with the link below.  Feel free to share with me your thoughts as to the motivation behind everyone's interest...

For those HW junkies, here's a great article that shows both the Tyan board and the Google board.  Notice that Tyan states their board is intended for developers.  (And you folks thought I hadn't been listening...geez, I'm just slow, not stupid.  ;-)

Anyone doubt that we're transforming the Power business still?
EnterpriseTech told you a few months ago that Google was working on its own server motherboards based on IBM’s Power8 processor and at the Impact2014 confe

Because #PowerKVM is new and brought to market on a short schedule, we've not been able to test all I/O adapters supported by +IBM Power Systems in the KVM host image.  As such, here's a link to the Knowledge Center article where we detail the supported list of adapters for PowerKVM.

Just saw a very nice demo of #PowerKVM and the Kimchi interface.  Passing this along for those of you trying to understand the differences between KVM and PowerVM or for those trying to get a feel if KVM on Power behaves differently than x86.

Enjoy!!!

Unofficial packages for OpenJDK 7 build from IcedTea 2.5.0 (indeed, JIT enabled!) are available for SLES 11 on PPC64 thanks to the great +Open Build Service (OBS) at build.opensuse.org

The easiest way is using zypper to add my repository and install:
$ zypper addrepo http://download.opensuse.org/repositories/home:tdaitx/SLE_11_SP3/home:tdaitx.repo
$ zypper refresh
$ zypper install java-1_7_0-openjdk

OpenJDK 7 packages can also be downloaded directly from https://build.opensuse.org/package/binaries/home:tdaitx/java-1_7_0-openjdk?repository=SLE_11_SP3

Please do get in touch in case of any problems.

Note: additional packages from either my home project [1], OBS [2], or SUSE official repositories might be needed depending on your particular system.

Note 2: I'm looking for a way to provide those same packages to RHEL 6 users, but so far I haven't found a public build server for it. The EPEL6 repositories for Koji at Fedora cannot be used since their policy forbids building packages that are officially available on RHEL repositories and COPR does not support PPC64. RHEL6 support for PPC64 at OBS is also lacking and currently lots of OpenJDK dependencies are not available there. If you know of any alternatives, please get in touch. ^_^

I'm closing in a build for RHEL6, thanks to +Dinar Valeev! Knowing that OBS had packages from DVD1 made my life much easier, and he has been a great help over IRC. ;-)

Now the last hurdle is that there's no package providing gnative2ascii on RHEL - by default it's provided by some gcc derived package, but RHEL's spec file just deletes the binary instead of packaging it. If anyone knows an easy way to get gnative2ascii (or it's alternative, native2ascii) up and running on OBS, please let me know.

Hey +Dinar Valeev, anytime I provide projections externally, because they can always change I use dates that should be attainable and hopefully will be exceeded.  We certainly recognize that LE on PowerVM (thus IFLs and larger systems) is high priority requirement.

The upcomming [1] IcedTea 7 version 2.5 [2] will finally bring JIT support to Java 7 in both PPC64 and PPC64LE systems by default - this is a merge from the great work done by the PPC-AIX-Port team [3 and 4]. For those that can't wait, grab your towels and build your own directly from the upstream IcedTea 7 sources:

$ hg clone http://icedtea.classpath.org/hg/icedtea7/
$ cd icedtea7
$ ./autogen.sh
$ ./configure
$ make

Of course, you will have to deal with all the required dependencies for your particular distro. Get in touch if you need help.

FYI IcedTea packages OpenJDK in a GNU/Linux friendly way, Andrew Hughes, IcedTea maintainer, has put it in much better words at his blog [4]. All known GNU/Linux distributions rely on IcedTea to provide their OpenJDK packages - if the IcedTea brand name is not shown in the package name, you might at least see which IcedTea version that was used; for JDK 7, the current IcedTea version is 2.4. Also, IcedTea major version indicates which OpenJDK is being packaged: IcedTea 1.x packages JDK 6, IcedTea 2.x packages JDK 7, and the upcoming IcedTea 3.x will package JDK 8.

A great video from  +Kangaroot Linux Solutions on their open source experience with postgresql detailing how #PowerLinux is on average 25% better with POWER7 than x86 servers.  I look forward to their update on POWER8!

I get questions all the time about mysql and keep pointing people to +MariaDB.  Articles like this and the actions to which they point set a clear picture of a trend in my mind.

Anyone else see this trend and care to share?

 A great whitepaper about #SAP on +PowerLinux!!!  You would not believe how often people are surprised to find out that SAP runs on Linux on Power.

One comment: the server used in this whitepaper is an S822 because when you run the Oracle DB you must use AIX.  If you wish to implement with DB2, you can buy an "L box" such as an S822L and run everything on Linux.  And do not forget that DB2 license is just 70 PVUs for Linux on Power.  Nice way to save some money!!!
