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: Vulkan SPIR OpenGL

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.

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.
