Khronos Group Releases NNEF 1.0 Standard for Neural Network Exchange

• Tags:

The Khronos Group announces the release of the Neural Network Exchange Format (NNEF™) 1.0 Provisional Specification for universal exchange of trained neural networks between training frameworks and inference engines. NNEF reduces machine learning deployment fragmentation by enabling a rich mix of neural network training tools and inference engines to be used by applications across a diverse range of devices and platforms. The release of NNEF 1.0 as a provisional specification enables feedback from the industry to be incorporated before the specification is finalized — comments and feedback are welcome on the NNEF GitHub repository. The goal of NNEF is to enable data scientists and engineers to easily transfer trained networks from their chosen training framework into a wide variety of inference engines. A stable, flexible and extensible standard that equipment manufacturers can rely on is critical for the widespread deployment of neural networks onto edge devices, and so NNEF encapsulates a complete description of the structure, operations and parameters of a trained neural network, independent of the training tools used to produce it and the inference engine used to execute it. Learn more about NNEF 1.0 Provisional Specification in the press release, or on the NNEF homepage.

Portable Computing Language (pocl) 1.0 has been released. One of the bigger highlights of this release is that most of the OpenCL 1.2 standard conformance tests pass with the CPU backend. There are some caveats though to this listed in the documentation. Pocl is a portable open source (MIT-licensed) implementation of the OpenCL standard (1.2 with some 2.0 features supported).

New Vulkan Benchmark test for Android

• Tags:

The 3DMark benchmark app for Android smartphones and tablets now includes a Vulkan benchmark test. Games typically make thousands of draw calls per frame, but each one creates performance-limiting overhead for the CPU. Vulkan reduces that overhead, which means games and apps can draw more objects, textures, and effects to the screen to create richer, more immersive experiences. You can now compare scores from Android devices using OpenGL ES 3.1 and Vulkan with scores from Apple iOS devices using Metal.

LunarG is pleased to announce the release of a new option in spirv-opt, which was designed to reduce SPIR-V size. This new option, -Os, allows developers to reduce SPIR-V size without specifying individual passes of spirv-opt. Learn more about this option at LunarG. For those developers who wish to have finer control over which passes are invoked, read more details about the available SPIR-V optimization options in the white paper by Greg Fischer of LunarG, titled SPIR-V Shader Size Reduction Using spirv-opt_v1.1.

AMD Adrenalin 17.12.1 Released with support for OpenGL 4.5/4.6 + Vulkan 1.0.65

• Tags:

Geeks 3D has a great overview of the new OpenGL and Vulkan features in the AMD Adrenalin 17.12.1 release. AMD has added some OpenGL 4.6 extensions (GL_ARB_gl_spirv) but not all, so Adrenalin 17.12.1 is still an OpenGL 4.5 driver with OpenGL 4.6 features. This driver exposes 319 OpenGL extensions (GL=294 and WGL=25) for a Radeon RX 470 on Windows 10 64-bit. Adrenalin 17.12.1 also exposes Vulkan 1.0.65 which is one of the latest specifications. Vulkan support has been added to Radeon Overlay, Radeon Relive, Enhanced Sync and Frame rate target control.

/assets/uploads/news/news_graphics/NNEF_170px_Apr17.png

There is a wide range of open-source deep learning training networks available today offering researchers and designers plenty of choice when they are setting up their project. Caffe, Tensorflow, Chainer, Theano, Caffe2, the list goes on and is getting longer all the time. This diversity is great for encouraging innovation, as the different approaches taken by the various frameworks make it possible to access a very wide range of capabilities, and, of course, to add functionality that’s then given back to the community. This helps to drive the virtuous cycle of innovation.
