While Fedora 21 is planning for open-source OpenCL support "out of the box", the same can't be said for Ubuntu 14.10. Ubuntu developers aren't looking for any stock OpenCL support be made available in the next distribution release.
While more OpenCL software is offering code-paths for OpenCL support from LibreOffice to The GIMP for faster processing by leveraging GPUs, there apparently isn't a compelling enough reason for Canonical to support OpenCL out-of-the-box on Ubuntu Linux quite yet. The open-source driver support for OpenCL continues to improve with Intel's Beignet and the OpenCL Gallium3D state tracker for the Radeon/Nouveau drivers, which can now run Bit Coin miners, etc.
Hewlett-Packard (HPQ) signaled its endorsement of Canonical's Ubuntu Linux as a platform for deploying the OpenStack cloud operating system with the release this week of a new reference architecture, which provides detailed instructions on setting up an OpenStack cloud using Ubuntu and other tools from Canonical, such as Juju and MAAS.
In 2013, Canonical - the company behind Ubuntu - attempted to raise $32m via crowdfunding for its Ubuntu Edge smartphone. It didn't make it, but the Ubuntu phone isn't dead. In fact, development is well under way and the Ubuntu phone operating system is very much alive. If you're brave enough, you can download and install the developer version on certain Android smartphones and tablets by following the instructions here.
Kubuntu14.10 Alpha 1 (Utopic Unicorn) is based on KDE 4.13.2, but the developers are tracking the upcoming KDE Frameworks 5, which is now in the works. It's been a long time since a Kubuntu development version didn't integrate an unstable version of KDE, but it looks like users will still be able to test what the makers of this distro are preparing.
“Plasma 1 is our recommended stable offering and what you get from the default download, but is now in maintenance mode. It runs the software you are familiar with and will be getting updates and bugfixes but not new features from now on.
The first alpha of the Utopic Unicorn (to become 14.10) has now been released!
This alpha features images for Kubuntu, Lubuntu Ubuntu GNOME,
UbuntuKylin and the Ubuntu Cloud images.
Pre-releases of the Utopic Unicorn are *not* encouraged for anyone
needing a stable system or anyone who is not comfortable running
into occasional, even frequent breakage. They are, however,
recommended for Ubuntu flavor developers and those who want to
help in testing, reporting and fixing bugs as we work towards getting
this release ready.
Unlike the previous development branch for Ubuntu 14.04, fewer developers chose to participate in the first Alpha release of 14.10. This is not something to worry about and it's likely that the second Alpha will have more exposure.
Canonical stopped releasing Alpha versions for its operating system for some time now, and only a few of the flavors have decided to keep doing this kind of releases. Ubuntu 14.10 will only get a Beta version right before launch so, until then, users can only expect the flavors to have intermediary builds.
