Using the Parallella with ‘R’ and OpenCL

‘R’ is a free software environment for statistical computing and graphics created in the early '90s. Work is under way to allow R to run on the Parallella board with the Epiphany16/64 chip using OpenCL.

Harlan targets complexity for GPGPU programming and compiles to OpenCL

HPC programmers who are tired of managing low-level details when using OpenCL or CUDA to write general purpose applications for GPUs (GPGPU) may be interested in Harlan, a new declarative programming language designed to mask the complexity and eliminate errors common in GPGPU application development. The idea with Harlan is to keep developers focused on the high-level HPC programming challenge at hand, instead of getting bogged down with the nitty gritty details of GPU development and optimization. Harlan's syntax is based on the language Scheme, and compiles to Khronos Group's OpenCL.

Squid HEVC decoders using OpenCL on ARM Cortex A-Series cores

Squid Systems announced today that leading broadcast equipment maker Harmonic and mobile software solutions leader NXP Software are demonstrating HEVC decoders at IBC 2013 based on the highly efficient Squid HEVC software decoder. Squid HEVC decoders run on CPU and CPU+GPU using OpenCL for platforms based on ARM Cortex A-Series cores and the Intel Atom (mobile) and high quality encoders on multi-core X86 processors.

Computational photography with ImgTec PowerVR SGX GPU and Khronos OpenCL and EGL

Imagination Technologies has developed a set of extensions to allow image conversion on the fly, using the Khronos Groups OpenCL and EGL technology. ImgTec converts the camera YUV data to RGB using the OES_EGL_image_external extension, and then use PowerVR’s zero-copy functionality to directly access the camera texture data from OpenCL. Find the in-depth explanation on ImgTec's website.

AMD using OpenCL with DaVinci Resolve 10 for real-time playback and editing

At at IBC this year, AMD demonstrated a 4K CinemaDNG workflow for Blackmagic Design DaVinci Resolve 10 color-grading. Using a Supermicro 7047GR-TRF SuperWorkstation to run four AMD FirePro W-series graphics cards, the GPU-accelerated workflow relied on Blackmagic's OpenCL support for Windows and Mac to enable real-time playback of CinemaDNG.

ARM announces suite of of Graphics Processing Technology supporting OpenGL ES 3.0

ARM unveiled new additions to its Mali GPU family. First up is the Mali-T760, ARM's most powerful GPU to-date, and secondly, the lower-end Mali-T720, ARM's first GPU for midrange devices that supports OpenGL ES 3.0 and OpenCL. ARM's share of the mobile GPU market is growing and now stands at 18 percent, according to Jon Peddie Research.

Amazon launches new EC2 GPU instances for high-performance 3D Graphics in the cloud

Amazon launched a new type of instance for its EC2 cloud computing platform that is specifically designed for applications that require 3D graphics capabilities. Using these new instances, Amazon argues, its users can now “build high-performance DirectX, OpenGL, CUDA, and OpenCL applications and services without making expensive up-front capital investments.” Amazon is making two of these new GPU instance types available for now. The g2.2xlarge version comes with 15 GB memory, 60 GB of local storage, 26 EC2 Compute Units (that’s an Intel Sandy Bridge processor running at 2.6 GHz) and a single NVIDIA Kepler GK104 graphics card (with 1536 CUDA cores). The larger cg1.4xlarge version comes with 22 GB of memory, 1690 GB of local storage, 33.5 EC2 Compute Units and two NVIDIA Tesla “Fermi” M2050 GPUs.
