AMD Goes Full Steam To Open-Source
AMD and now RTG (Radeon Technologies Group) are involved in a major push to open source GPU resources.
According to Ars Technica Under the handle “GPUOpen” AMD is releasing a slew of open-source software and tools to give developers of games, heterogeneous applications, and HPC applications deeper access to the GPU and GPU resources.
In a statement AMD said that as a continuation of the strategy it started with Mantle, it is giving even more control of the GPU to developers.
“ As console developers have benefited from low-level access to the GPU, AMD wants to continue to bring this level of access to the PC space.”
The AMD GPUOpen initiative is meant to give developers the ability to use assets they’ve already made for console development. They will have direct access to GPU hardware, as well as access to a large collection of open source effects, tools, libraries and SDKs, which are being made available on GitHub under an MIT open-source license.
AMD wants GPUOpen will enable console-style development for PC games through this open source software initiative. It also includes an end-to-end open source compute infrastructure for cluster-based computing and a new Linux software and driver strategy
All this ties in with AMD’s Boltzmann Initiative and an HSA (Heterogeneous System Architecture) software suite that includes an HCC compiler for C++ development. This was supposed to open the field of programmers who can use HSA. A new HCC C++ compiler was set up to enable developers to more easily use discrete GPU hardware in heterogeneous systems.
It also allows developers to convert CUDA code to portable C++. According to AMD, internal testing shows that in many cases 90 percent or more of CUDA code can be automatically converted into C++ with the final 10 percent converted manually in the widely popular C++ language. An early access program for the “Boltzmann Initiative” tools is planned for Q1 2016.
AMD GPUOpen includes a new Linux driver model and runtime targeted at HPC Cluster-Class Computing. The headless Linux driver is supposed to handle high-performance computing needs with low latency compute dispatch and PCI Express data transfers, peer-to-peer GPU support, Remote Direct Memory Access (RDMA) from InfiniBand that interconnects directly to GPU memory and Large Single Memory Allocation support.

AMD Appears To Be Pushing It’s Boltzmann Plan
Comments Off on AMD Appears To Be Pushing It’s Boltzmann Plan
Troubled chipmaker AMD is putting a lot of its limited investment money into the “Boltzmann Initiative” which is uses heterogeneous system architecture ability to harness both CPU and AMD GPU for compute efficiency through software.
VR-World says that stage one results are finished and where shown off this week at SC15. This included a Heterogeneous Compute Compiler (HCC); a headless Linux driver and HSA runtime infrastructure for cluster-class, High Performance Computing (HPC); and the Heterogeneous-compute Interface for Portability (HIP) tool for porting CUDA-based applications to C++ programming.
AMD hopes the tools will drive application performance from machine learning to molecular dynamics, and from oil and gas to visual effects and computer-generated imaging.
Jim Belak, co-lead of the US Department of Energy’s Exascale Co-design Center in Extreme Materials and senior computational materials scientist at Lawrence Livermore National Laboratory said that AMD’s Heterogeneous-compute Interface for Portability enables performance portability for the HPC community.
“The ability to take code that was written for one architecture and transfer it to another architecture without a negative impact on performance is extremely powerful. The work AMD is doing to produce a high-performance compiler that sits below high-level programming models enables researchers to concentrate on solving problems and publishing groundbreaking research rather than worrying about hardware-specific optimizations.”
The new AMD Boltzmann Initiative suite includes an HCC compiler for C++ development, greatly expanding the field of programmers who can leverage HSA.
The new HCC C++ compiler is a key tool in enabling developers to easily and efficiently apply the hardware resources in heterogeneous systems. The compiler offers more simplified development via single source execution, with both the CPU and GPU code in the same file.
The compiler automates the placement code that executes on both processing elements for maximum execution efficiency.

Will AMD’s Newest SoC Save The Company?
Comments Off on Will AMD’s Newest SoC Save The Company?
The troubled chipmaker AMD thinks it is onto a winner with its new AMD Embedded R-Series SOC processors.
Designed for demanding embedded needs, the processors incorporate the newest AMD 64-bit x86 CPU core (“Excavator”), plus third-generation Graphics Core Next GPU architecture, and better power management for reduced energy consumption.
AMD tells us that combined, these chips provide industry-leading graphics performance and key embedded features for next-generation designs. The SOC architecture enables simplified, small form factor board and system designs from AMD customers and a number of third party development platform providers.
What AMD brings to the party is its graphics and multimedia performance, including capability for hardware-accelerated decode of 4K video playback and support for the latest DDR4 memory.
Jim McGregor, principal analyst, TIRIAS Research said that AMDs push into x86 embedded platforms is paying off with an increasing number of customers and applications.
“There is a need for immersive graphics, high-quality visualization, and parallel computing in an increasing number of embedded applications. Across these fronts, the AMD Embedded R-Series SOC is a very compelling solution.”
Scott Aylor, corporate vice president and general manager, AMD Embedded Solutions said that his outfit’s AMD Embedded R-Series SOC is a strong match for these needs in a variety of industries including digital signage, retail signage, medical imaging, electronic gaming machines, media storage, and communications and networking.
“The platform offers a strong value proposition for this next generation of high-performance, low-power embedded designs.”
The new AMD Embedded R-Series SOCs offer 22 percent improved GPU performance when compared to the 2nd Generation AMD Embedded R-Series APU2 and a 58 percent advantage against the Intel Broadwell Core i7 when running graphics-intensive benchmarks.
AMD released some of the specs for its integrated AMD Radeon graphics including:
Up to eight compute units4 and two rendering blocks
GPU clock speeds up to 800MHz resulting in 819 GFLOPS
•DirectX 12 support
Fully HSA Enabled
The AMD Embedded R-Series SOC was architected with embedded customers in mind and includes features such as industrial temperature support, dual-channel DDR3 or DDR4 support with ECC (Error Correction Code), Secure Boot, and a broad range of processor options.
It has a configurable thermal design power (cTDP) allows designers to adjust the TDPs from 12W to 35W in 1W increments for greater flexibility.
The SOC also has a 35 percent reduced footprint when compared to the 2nd Generation AMD Embedded R-Series APU, making it an excellent choice for small form factor applications.
AMD said that the range is the first embedded processor with dual-channel 64-bit DDR4 or DDR3 with Error-Correction Code (ECC), with speeds up to DDR4-2400 and DDR3-2133, and support for 1.2V DDR4 and 1.5V/1.35V DDR3.
Its dedicated AMD Secure Processor supports secure boot with AMD Hardware Validated Boot (HVB) and initiates trusted boot environment before starting x86 cores
It has a high-performance Integrated FCH featuring PCIe Gen3 USB3.0, SATA3, SD, GPIO, SPI, I2S, I2C, and UART
The AMD Embedded R-Series SOC provides industry-leading ten-year longevity of supply. The processors support Microsoft Windows 7, Windows Embedded 7 and 8 Standard, Windows 8.1, Windows 10, and AMD’s all-open Linux driver including Mentor Embedded Linux from Mentor Graphics and their Sourcery CodeBench IDE development tools.
It will be interesting to see if AMD can make up the ground it has lost on PCs and higher ticket items. Most of the company still appears to be in a holding pattern until Zen arrives.

Scientist Develop Anti-Faking PC
Scientists have developed a computer system with sophisticated pattern recognition abilities that performed more impressively than humans in differentiating between people experiencing genuine pain and people who were just pretending.
In a study published in the journal Current Biology, human subjects did no better than chance – about 50 percent – in correctly judging if a person was feigning pain after seeing videos in which some people were and some were not.
The computer was right 85 percent of the time. Why? The researchers say its pattern-recognition abilities successfully spotted distinctive aspects of facial expressions, particularly involving mouth movements, that people generally missed.
“We all know that computers are good at logic processes and they’ve long out-performed humans on things like playing chess,” said Marian Bartlett of the Institute for Neural Computation at the University of California-San Diego, one of the researchers.
“But in perceptual processes, computers lag far behind humans and have a lot of trouble with perceptual processes that humans tend to find easy, including speech recognition and visual recognition. Here’s an example of a perceptual process that the computer is able to do better than human observers,” Bartlett said in a telephone interview.
For the experiment, 25 volunteers each recorded two videos.
In the first, each of the volunteers immersed an arm in lukewarm water for a minute and were told to try to fool an expert into thinking they were in pain. In the second, the volunteers immersed an arm in a bucket of frigid ice water for a minute, a genuinely painful experience, and were given no instructions on what to do with their facial expressions.
The researchers asked 170 other volunteers to assess which people were in real discomfort and which were faking it.
After they registered a 50 percent accuracy rate, which is no better than a coin flip, the researchers gave the volunteers training in recognizing when someone was faking pain. Even after this, the volunteers managed an accuracy rate of only 55 percent.
The computer’s vision system included a video camera that took images of a person’s facial expressions and decoded them. The computer had been programmed to recognize that one kind of facial movement combinations suggested true pain and another kind suggested faked pain.
HP Goes All-In On Tablets
Hewlett-Packard garnered attention at Mobile World Congress show with its new Slate 7-inch tablet and then the sale of webOS assets, but the company is looking to put past distractions behind and will release more tablets in the future, the company said.
“You can expect going forward [to release] a family of products,” said Shane Wall, chief technology officer at Hewlett-Packard’s mobility group, in an interview at MWC. The mobility trade show is being held in Barcelona from Feb. 25 to 28.
The 7-inch tablet attracted a small crowd at the HP booth, with people lining up to photograph or use the device. The company effectively took a dive into the low-cost tablet and tried to differentiate its tablet by a lower price, and also features like a micro-SD card slot for expandable storage and dual-cameras. Google’s $199 Nexus 7 is priced higher and has a quad-core processor, a higher-resolution screen and Android 4.2, but HP believes it will sell a lot of the tablets at the $169 price.
“We’re obviously late,” Wall said. “We wanted to start and see how aggressive we can be on the low end.”
The Slate 7 also signifies HP’s re-entry into the consumer tablet market after a disastrous stint with the webOS mobile operating system, which it got with the acquisition of Palm in 2010 for $1.2 billion. The first webOS tablet, the TouchPad, was launched in 2011, but later discontinued along with webOS smartphones. Since then HP has released enterprise tablets such as ElitePad 900 with Windows 8, and now the company has adopted Android for consumer tablets.
