AMD announced its third annual Developer Summit last week. Dubbed “APU13,” the upcoming summit is the AMD equivalent to NVIDIA’s GTC and is an annual event that brings together industry analysts, researchers, programmers, academics, and software/hardware companies pursuing heterogeneous computing technologies.

In previous years, the AMD Developer Summit has been the launchpad for C++ AMP and the HSA Foundation. This year’s Summit will continue that trend towards heterogeneous computing as well as look back over the year and provide updates on where the various HSA member companies are at as far as goals to move towards standards-based heterogenous computing.

In addition to keynote speeches from AMD and some of its partners, expect a great deal of presentations and workshops from researchers and programmers that are working on new programming models and hardware solutions to efficiently use CPU and GPU processors. More information on hUMA is one of the likely topics, for example. Discussion about upcoming hardware, process nodes, and products may also be on the table so far as it relates to the HSA theme. Considering the summit is called “APU13,” I also expect that AMD will reveal additional details on the company’s Kaveri APU as well as a look into its future product road map.

AMD is currently asking for presentation proposals from researchers in a number of HSA and technology-related fields including heterogeneous computing, cloud computing, web technologies, programming languages, gaming and graphics technologies, and software security. The lineup of presenters for the summit is still being worked out, and proposal papers will be accepted until May 10th with the winners being notified over the summer.

In all, AMD’s APU13 should be an exciting and intellectual event. Last year’s AMD Fusion Developer Summit (AFDS) was an interesting and fun event to cover, and I hope that APU13 will keep up the same momentum and interest in heterogeneous computing that AFDS started.

hUMA has come with a weapon to slay the memory latency dragon

AMD may have united GPU and CPU into the APU but one hurdle had remained until now, the the non-uniformity of memory access between the two processors.  Today we learned about one of the first successful HAS projects called Heterogeneous Uniform Memory Access, aka hUMA, which will appear in the upcoming Kaveri chip family.   The use of this new technology will allow the on-die CPU and GPU to access the same memory pool, both physical and virtual and any data passed between the two processors will remain coherent.  As The Tech Report mentions in their overview hUMA will not provide as much of a benefit to discrete GPUs, while they will be able to share address space the widely differing clock speeds between GDDR5 and DDR3 prevent unification to the level of an APU.

Make sure to read Josh's take as well so you can keep up with him on the Podcast.

"At the Fusion Developer Summit last June, AMD CTO Mark Papermaster teased Kaveri, AMD's next-generation APU due later this year. Among other things, Papermaster revealed that Kaveri will be based on the Steamroller architecture and that it will be the first AMD APU with fully shared memory.

Last week, AMD shed some more light on Kaveri's uniform memory architecture, which now has a snazzy marketing name: heterogeneous uniform memory access, or hUMA for short."

New Ubuntu 13.04 Release Upgrades Unity, Ditches Wubi, and Updates Applications

Subject: General Tech | April 30, 2013 - 12:57 PM | Tim Verry

Canonical released its the Ubuntu 13.04 “Raring Ringtail” Linux distribution earlier this week. The updated operating system incorporates a new Linux kernel, newer pre-installed applications, and a tweaked Unity desktop environment. Enterprise and server users also have updated server software stacks to look forward to, including the latest juju and OpenStack (Grizzly) releases.

Ubuntu 13.04 continues in the direction of convergence set in motion by Canonical and its founder Mark Shuttleworth. It is the first step towards Ubuntu running on many types of devices (including mobile) as it includes an updated Unity interface. The 13.04 release still uses the X window system, but Canonical has made tweaks to Unity and is offering up an optional download of the new Mir display backend that users can install. Mir is the display server that Ubuntu will be switching to with its next LTS release and that will reportedly enable a cross-platform Ubuntu/Unity experience. The Unity tweaks include disabling Workspaces and the “show desktop” button on the desktop (though they can be re-enabled in settings). There have also been tweaks to Ubuntu’s Dash UI, including a typo-tolerant search function and new result sorting options. It will not be until the next release that users will really start to see Ubuntu’s plans of convergence come together (heh), but even with the small changes present in 13.04, the traditional desktop OS is making considerations for mobile devices.

While the visual changes are minimal on Ubuntu 13.04 compared to 12.10, the new release does update a lot of the underlying software.At least on the outside, Ubuntu 13.04 has not changed much from its 12.10 predecessor. Ubuntu 13.04 is based on the upstream 3.8.8 Linux kernel, and incorporates a number of updates to the pre-installed applications and core software. The updates include Unity 7, LibreOffice 4, and Python 3.3 (future versions of Ubuntu will remove Python 2 completely, though it will still be available as a downloadable package). Gwibber has also been replaced with a new service called “Friends” that takes all of your social networking accounts and combines them under your Ubuntu Online account.

Additionally, Ubuntu 13.04 also no longer includes the Wubi installer, which allowed users to install Ubuntu as a program within Windows and got around the need to mess with partitioning. Although there was a bit of overhead in doing the install this way, it was noticeably easier for new users than other methods. Canonical suggests that users interested in trying out the new operating system should simply use the live media, but installing it in a VM such as VirtualBox or VMWare may be more appropriate as some of the functionality is missing from the Live DVD environment in my experience (at least if you also want to try out functionality or other Linux software that would require a restart). Canonical has also cut the support time in half for Ubuntu 13.04 (and all future interim releases) from 18 months to 9 months. Hopefully the development team puts the reduced support workload to good use by investing the time in quick and stable releases.

So far, Ubuntu 13.04 has been getting positive reviews, though some users have run into issues running the operating system on their particular hardware (a bit of instability is expected with a new release, however).

If you are interested in Ubuntu 13.04 “Raring Ringtail,” you can read more about the changes in the official release notes and grab a download of the OS from the Ubuntu website or the updater if you are currently running Ubuntu 12.10.

New Linux Kernel 3.9 Adds New Features Including KVM on ARM and SSD Caching Support

Subject: General Tech | April 30, 2013 - 09:46 AM | Tim Verry

Linus Torvalds recently released a new version of the Linux kernel -- version 3.9 -- that advances the core of the GNU/Linux operating system with a number of new features. Among other tweaks, the new kernel rolls in new drivers, improves virtualization support, adds new hardware sleep modes, and tweaks file system and storage support.

The new kernel has added quite a few new experimental features, but developers/enthusiasts will no longer have to employ the CONFIG_EXPERIMENTAL flag when compiling the kernel in order to enable them. The kernel development team has decided to remove that option, enable the features by default, and merely tag those experimental features in the documentation. One of the experimental features is SSD caching that allows a solid state drive to cache both reads and writes. The SSD can cache frequently accessed data on the faster solid state drive as well as take the write cached data and write it to the hard drive when the IO subsystem isn’t being heavily utilized. The feature is not new to Linux distributions, but the caching support has now been moved to the kernel. Furthermore, the kernel is now RAID-aware when using the btrfs file system and RAID 5 or RAID 6.

On the driver front, Linux Kernel 3.9 now supports Intel’s upcoming 802.11ac Wi-Fi adapters, improved HD audio codec, AMD’s Oland (8500/8600) and Richland GPUs, and additional NVIDIA GPU support. The new kernel also rolls in a power-optimized driver for Intel’s Haswell GPU and several more track pads.

Kernel 3.9 also adds a new suspend/sleep mode. It will use more power than the traditional S3 (suspend to memory) sleep mode because components are not completely powered down (merely at their lowest sleep mode), but the system will be almost-instantly accessible upon exiting the new suspend mode as a result. According to H-Online, this "lightweight suspend" mode would be ideal for mobile devices or hardware used in network appliances. Also interesting is support for a KVM hypervisor on ARM Cortex A15 SoCs as well as some software tweaks to the kernel to improve web server workloads by allowing multiple networking sockets (and associated CPU processes) to listen on the same network port.

In all, version 3.9 looks to be a worthy upgrade, and one that I hope Linux distro makers will opt for in upcoming releases. I think the new drivers and the SSD caching being rolled into the kernel are the most important features for desktop users, though the networking stack improvements also sound interesting.

For more details, Thorsten Leemhuis has written up an extensive article on the new kernel.

Can you go too far with a gaming mouse? The Shogun Bros Ballista MK-1 Pro

Tagged: Shogun Brothers Ballista MK-1 Pro, input, gaming mouse

Gaming mice continue to evolve as the market has become saturated, with companies striving to stand out in the crowd but Shogun Brothers may have taken this a bit far.  While having 8200 DPI and 12000 FPS is impressive, being able to set the X and Y sensitivity separately seems excessive.  The ability to save five different profiles for button programming is impressive but when the mouse is capable of displaying the name of that profile you have perhaps reached a new level altogether.  Perhaps the most telling is that the mouse is clearly labelled with a warning not to even attempt to use the mouse without reading the instructions first.  However, if this sounds like the mouse of your dreams, head to eTeknix to see this mouse in action.

"For the last couple of days I have been spending my evening gaming and putting the Ballista MK-1 gaming mouse from Shogun Bros through its paces. Until a few weeks ago I had never even heard of Shogun Bros and give that the gaming peripheral is somewhat dominated by a few big brands it can be hard for another name to squeeze through. Yet a quick look online has shown that products like the Ballista and other products from Shogun Bros have been getting a lot of attention and a lot of love from both review media and the gaming community, so what is all the fuss about?"
