When it comes to multi-GPU (mGPU), most developers immediately think of complicated Crossfire setups with two or more GPUs and how to make their game run well on those setups. This is however only one side of the mGPU story – the other one is mGPU during content creation. If you’re a developer working on a game, you should think of using mGPU to make your life easier.


Here is a simple weather station, coded with GeeXLab, that woks with the Raspberry Pi and the Sense HAT:

3D-Tech News Around The Web / NVIDIA Volta GPU thread
« on: April 18, 2017, 02:30:20 PM »
First news about Volta appeared few years ago in 2013:

According to these recent rumors, NVIDIA Volta-based graphics cards (GeForce 20 Series - GTX 2080...) should arrive during Q3 2017:

- NVIDIA to launch next-gen Volta-based GeForce in Q3 2017
- Pascal lineup is complete now that NVIDIA launched Titan Xp and is about to launch GeForce GTX 1030
- Based on their traditional upgrade cycle we should expect Volta by the end of the year or early 2018, but NVIDIA changed plans
- Market situation in Q1-2017 was bad, graphics and other hardware sales in decline, price war, meager profits, sales not increasing the way they want to (vicious circle)
- According to the latest news, NVIDIA plans to release GeForce 20 series in advance, it is now expected to be released in the third quarter of this year
- GeForce 20 series product prices, market positioning will be replanned
- By launching sooner than expected they will be able to increase prices of single cards and increase profits

3D-Tech News Around The Web / AMD Ryzen 5 Processor Series Launched
« on: April 11, 2017, 04:08:22 PM »
AMD Ryzen5:  6-core (12-thread) and 4-core (8-thread) processors launched.


NVIDIA has announced the Tesla P100 (Pascal architecture), the first compute card with 12GB or 16GB of HBM2 stacked memory. AMD has been the first GPU maker to release a card with HBM memory (Radeon Fury) but NVIDIA is the first to release a card with HBM2.

Artificial intelligence for self-driving cars. Predicting our climate's future. A new drug to treat cancer. Some of the world's most important challenges need to be solved today, but require tremendous amounts of computing to become reality. Today's data centers rely on many interconnected commodity compute nodes, limiting the performance needed to drive important High Performance Computing (HPC) and hyperscale workloads.

NVIDIA® Tesla® P100 GPU accelerators are the most advanced ever built for the data center. They tap into the new NVIDIA Pascal™ GPU architecture to deliver the world's fastest compute node with higher performance than hundreds of slower commodity nodes. Higher performance with fewer, lightning-fast nodes enables data centers to dramatically increase throughput while also saving money.

3D-Tech News Around The Web / Let's fix OpenGL
« on: April 10, 2017, 05:38:51 PM »
From windowing systems to virtual reality, real-time graphics code is ubiquitous. Programming
models for constructing graphics software, however, have largely escaped the attention of pro-
gramming languages researchers. This essay introduces the programming model of OpenGL, a
ubiquitous API for real-time graphics applications, for a language-oriented audience. It high-
lights six broad problems with the programming model and connects them to traditions in PL
research. The issues range from classic pitfalls, where established thinking can apply, to new
open problems, where novel research is needed.

DepthOfFieldFX is a DirectX 11 library that provides a GCN-optimized Compute Shader implementation of Depth of Field.

The DepthOfFieldFX library provides a GCN-optimized Compute Shader implementation of Depth of Field using the Fast Filter Spreading approach put forth by Todd Jerome Kosloff, Justin Hensley, and Brian A. Barsky in their 2009 paper – Fast Filter Spreading and its Applications.

The library implements depth of field using a Bartlett and Box filter. There is an option to run the Bartlett at quarter resolution for improved performance in some cases. The advantage of this approach is a fixed performance cost that is not dependent on kernel size. The library takes the scene Color Buffer and Circle of Confusion buffer as input and an Unordered Access View for the final results.


You might have read that Microsoft will stop supporting Windows Vista on April 11. Futuremark will stop supporting two Windows Vista benchmarks, 3DMark Vantage and PCMark Vantage, on the same day.


3DMark Vantage and PCMark Vantage support ends April 11
Our Vantage benchmarks were designed for Windows Vista, an operating system that is over 10 years old and which is now used by only 1.12% of Windows users according to StatCounter.
From April 11, 3DMark Vantage and PCMark Vantage will:
- No longer be sold on our website.
- No longer receive updates, (other than SystemInfo).
- No longer be guaranteed to work with our online services.
- No longer be eligible for customer support.

Alternatives to 3DMark Vantage
3DMark Vantage is a benchmark for DirectX 10, an API which is now two generations old. For benchmarking modern gaming systems, we recommend using the latest 3DMark benchmarks:
- 3DMark Time Spy for DirectX 12 systems.
- 3DMark Fire Strike for high performance DirectX 11 PCs.
- 3DMark Sky Diver for DirectX 11 laptops and mid-range PCs.

Alternatives to PCMark Vantage
PCMark Vantage is a system benchmark for Windows Vista. If your PC is less than seven years old, you will get more relevant results by using a more recent version of PCMark. We recommend:
- PCMark 7 for Windows 7
- PCMark 8 for Windows 8
- PCMark 10, coming soon, for Windows 10.

Legacy benchmarks are free to download
All of our legacy benchmarks going back to 3DMark99 are available to download for free from our website. Each benchmark comes with a key to unlock the Advanced Edition features. 3DMark Vantage and PCMark Vantage will be available for free from April 11.
