Follow-up: Neil Trevett and Tom Olson from Khronos Group Discuss OpenCL and Vulkan Roadmap

• Tags:

PC Perspective had the opportunity to have a phone interview with Neil Trevett, president of the Khronos Group and chairman of the OpenCL working group, and Tom Olson, chairman of the Vulkan working group. While OpenCL is planning to merge into the Vulkan API, the Khronos Group wants to make it clear that “all of the merging” is coming from the OpenCL working group. The Vulkan API roadmap is not affected by this decision. Of course, the Vulkan working group will be able to take advantage of technologies that are dropping into their lap, but those discussions have not even begun yet. Read the entire post to learn more about the exciting future of OpenCL and Vulkan.

Intel Open Sources OpenCL Deep Neural Network library for Intel GPUs

• Tags:

The Intel Compute Library for Deep Neural Networks (clDNN) is an open source performance library for Deep Learning (DL) applications intended for acceleration of DL inference on Intel® Processor Graphics (Intel® HD Graphics and Intel® Iris® and Intel® Iris® Pro). clDNN includes highly optimized building blocks to implement convolutional neural networks (CNN) with C and C++ interfaces. This library is also used in the Deep Learning Toolkit found in the Intel Computer Vision SDK Beta. The clDNN library can be accessed at github. To learn more on how to use clDNN see whitepaper

OpenCL.org restarts the GEGL-OpenCL project

• Tags:

The Generic Graphics Library (GEGL) is best known as the backend for image processing software Gimp. GEGL is a graph based image processing framework that allows users to chain together image processing operations represented by nodes into a graph. It provides operations for loading and storing images, adjusting colors, filtering in different ways, transforming and compositing images. GEGL-OpenCL is an educational initiative that aims to get more developers to study and use OpenCL in their projects.

The Khronos Group announces the immediate availability of the finalized OpenCL™ 2.2 specification, incorporating industry feedback received from developers during the provisional specification review period. In addition to releasing the specification in final form, Khronos has, for the first time, released the full source of the specifications and conformance tests for OpenCL 2.2 onto GitHub to enable deeper community engagement. The conformance tests for OpenCL versions 1.2, 2.0 and 2.1 have also been released on GitHub with more open-source releases to follow. The Windsor Testing Framework, also released today, enables developers to quickly install and configure the OpenCL Conformance Test Suite on their own systems. Developers who know OpenCL C and plan to port their kernels to OpenCL C++, the OpenCL C to OpenCL C++ Porting Guidelines have been released.

Imagination Technologies announces the first GPU IP core based on its new PowerVR Furian architecture, the Series8XT GT8525. Says Tatiana Solokhina, CTO, RnD Center ELVEES, a Khronos member: “As a provider of SoCs for a wide range of global video analytics applications, we require a GPU that offers the best compute performance in a power constrained footprint. The new PowerVR Furian 8XT family from Imagination provides us an industry-leading GPU with new ALU for increased performance density and efficiency. In addition, support for standard compute APIs such as OpenVX enables easy implementation of real world vision processing applications.” Furian is designed to address the increasing compute requirements across multiple applications and market segments with efficient use of compute APIs including OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1.

Five years ago The International Workshop on OpenCL (IWOCL – "eye-wok-ul") started as a small OpenCL-focused conference. In 2017 it has grown to three full days filled with tutorials, talks, posters and many technical discussions. You’ll hear attendees (and yourself) saying, "I did not know this was going on and I should have known it before." It is a great place to learn the latest on OpenCL. Learn more about the history of IWOCL and the upcoming IWOCL event May 16-18, 2017 in Toronto, Canada.
