"... if you thought that your new 802.11ac router’s maximum speed of 1,300Mbps was already fast, think again. With 802.11ac fully certified and out the door, the Wi-Fi Alliance has started looking at its successor, 802.11ax — and it looks pretty enticing. While you may have a hard time getting more than 400Mbps to your smartphone via 802.11ac, 802.11ax should deliver real world speeds above 2Gbps. And in a lab-based trial of technology similar to 802.11ax, Huawei recently hit a max speed of 10.53Gbps, or around 1.4 gigabytes of data transfer per second. Clearly, 802.11ax is going to be fast. But what is it exactly?"

The final release of Ubuntu 15.04 is now available. A modest set of improvements are rolling out with this spring's Ubuntu. While this means the OS can't rival the heavy changelogs of releases past, the adage "don't fix what isn't broken" is clearly one 15.04 plays to. The headline change is systemd being featured first time in a stable Ubuntu release, which replaces the inhouse UpStart init system. The Unity desktop version 7.3 receives a handful of small refinements, most of which aim to either fix bugs or correct earlier missteps (for example, application menus can now be set to be always visible). The Linux version is 3.19.3 further patched by Canonical. As usual, the distro comes with fresh versions of various familiar applications.

NVIDIA's Maxwell GPU architecture has has been well-received in the gaming world, thanks to cards like the GeForce GTX Titan X and the GeForce GTX 980. NVIDIA recently took time to bring that same Maxwell goodness over the workstation market as well and the result is the new Quadro M6000, NVIDIA's new highest-end workstation platform. Like the Titan X, the M6000 is based on the full-fat version of the Maxwell GPU, the G200. Also, like the GeForce GTX Titan X, the Quadro M6000 has 12GB of GDDR5, 3072 GPU cores, 192 texture units (TMUs), and 96 render outputs (ROPs). NVIDIA has said that the M6000 will beat out their previous gen Quadro K6000 in a significant way in pro workstation applications as well as GPGPU or rendering and encoding applications that can be GPU-accelerated. One thing that's changed with the launch of the M6000 is that AMD no longer trades shots with NVIDIA for the top pro graphics performance spot. Last time around, there were some benchmarks that still favored team red. Now, the NVIDIA Quadro M6000 puts up pretty much a clean sweep.

Data in the Fast Lane: How NVLink Unleashes Application Performance

" ... To avoid “traffic jams” in applications, we invented a fast interconnect between the CPU and GPU, and among GPUs. It’s called NVLink.

It’s the world’s first high-speed interconnect technology for GPUs. NVIDIA NVLink creates a data super-highway in next-gen HPC servers. One that lets GPUs and CPUs exchange data among each other five to 12 times faster than with PCIe."

"RancherOS, the latest minimal Linux-based operating system for running Docker containers, was recently launched by Darren Shepherd, Rancher Lab's CTO. In contrast with Boot2Docker (another lightweight Docker-centric distribution) which openly discourages production use, RancherOS's announcement claims the new OS is production and scale-ready."

"A large amount of numerically-oriented code is written and is being written in legacy languages. Much of this code could, in principle, make good use of data-parallel throughput-oriented computer architectures. Loo.py, a transformation-based programming system targeted at GPUs and general data-parallel architectures, provides a mechanism for user-controlled transformation of array programs. This transformation capability is designed to not just apply to programs written specifically for Loo.py, but also those imported from other languages such as Fortran. It eases the trade-off between achieving high performance, portability, and programmability by allowing the user to apply a large and growing family of transformations to an input program. These transformations are expressed in and used from Python and may be applied from a variety of settings, including a pragma-like manner from other languages."

"Intel is targeting big core performance and intelligence in a microserver form factor with its new Xeon D family of processors, the company's first ever Xeon-based System-on-Chip (SoC) design. The Xeon D line Intel is announcing today is built on their 14nm process technology and combines the performance and features of its traditional Xeon chips with the size and power savings of an SoC. According to Intel, Xeon D delivers up to 3.4x faster performance node and up to 1.7x better performance per watt compared to the company's Atom C2750. The Xeon D is the third generation of the family and it's actually based on Intel's Broadwell architecture. Intel unveiled two new Xeon D processors today, the D-1540 (8 cores, 16 threads, 2GHz, 45W TDP) and D-1520 (4 cores, 8 threads, 2.2GHz, 45W TDP). These chips have memory controllers capable of addressing up to 128GB. They also feature an integrated platform controller hub (PCH), integrated I/Os, and two integrated 10 Gigabit Ethernet ports. Again, all of this is based on Intel's Broadwell core CPU architecture, so performance per watt should be strong."

"Intel just wrapped up an event at a location adjacent to the Game Developers Conference where the company discussed some updates to its 5th Gen Core processor line-up, Intel graphics developments, the Intel Hardware SDK, and its various game developer tools.
...
Chris Silva, Director of Marketing for Premium Notebook and Client Graphics teams, disclosed a few details of a couple of upcoming pieces of hardware. A socketed, unlocked, 65W desktop processor based on Intel’s Broadwell architecture--featuring Iris graphics--is on the way and due to arrive sometime in mid-2015. It’s noteworthy because this will be Intel’s first desktop CPU with Iris Pro graphics and because it is unlocked. It will be interesting to see what Iris Pro can do with some overclocking."

"Gaming enthusiasts have been griping for months that Nvidia's GeForce GTX 970 graphics chip doesn't operate up to snuff, and now someone has taken the company to court over it.

...

Nvidia markets the chip as having 4GB of performance-boosting video RAM, but some users have complained the chip falters after using 3.5GB of that allocation."

3D-Tech News Around The Web / Smart Rendering for Virtual Reality
« on: February 20, 2015, 06:01:24 PM »
"Researchers from Intel have been working on new methods for improving the rendering speed for modern wide-angle head-mounted displays like the Oculus Rift and Google Cardboard. Their approach makes use of the fact that because of the relatively cheap and lightweight lenses the distortion astigmatism happens: only the center area can be perceived very sharp, while with increasing distance from it, the perception gets more and more blurred. So what happens if you don't spend the same amount of calculations and quality for all pixels? The blog entry gives hints to future rendering architectures and shows performance numbers."

"Public clouds are great.  They offer great elasticity and cost savings, and in the case of a PaaS like Bluemix, allows us (developers) to forget about maintaining any infrastructure and focus in on our code.  However we all realize that public cloud can’t be used for everything.  There are some applications and services that must remain in our own data centers on private networks.  The reasons why vary, maybe it is too much work to move the resource to the cloud, or maybe the data in the resource is too sensitive to risk exposing outside of your firewall.  Whatever the reason may be, you are bound to come across a scenario where you need to access private resources in your public cloud applications.  What are your options?  One option is to try to setup some type of VPN and create a secure connection between the public cloud and your private network.  This is probably the route to take if you are using an IaaS provider like SoftLayer to run your application.  With a PaaS this is not possible, you don’t have access to the machine your application is running on or the network it is using, so if you choose Bluemix to deploy your application what are your options?

Luckily Bluemix has a solution for this problem and it is called Cloud Integration."
