The Khronos Group has posted most of the slide presentations from the SIGGRAPH BOFs online. Slide sets include COLLADA, OpenCL, OpenGL, OpenGL ES and WebGL. Developers will be particularly interested in these slides which include overviews of OpenGL 4.3, OpenGL ES 3.0 and CLU extension. There is also the slide deck from Kurt Akeley.

The OpenCL ICD extension (cl_khr_icd) allows multiple implementations of OpenCL to co-exist on the same system. The OpenCL ICD Loader Library allows applications to choose a platform from the list of installed platforms and dispatches OpenCL API calls to the underlying implementation. Source code for the ICD loader library is available in the Khronos registry. Consult LICENSE.txt in the tarball for full terms and conditions.

OpenCL News is reporting that the new APP SDK 2.8 includes dozens of new and improved samples for OpenCL, Aparapi and C++ AMP that deliver significantly faster performance than APP SDK 2.7 – up to 2.3x faster on average in nine key benchmarks. The APP SDK 2.8 also includes a preview version of AMD’s new open source C++ template library, codename "Bolt."

JavaCL 1.0.0-RC3 was just released and brings lots of bugfixes, massive performance improvements and preliminary OSGi support. This BSD-licensed library gives Java developer all the power of OpenCL, with just a single cross-platform JAR to put in their classpath (no native libraries headache). The release notes and JavaCL download are available online.

Virtual OpenCL (VCL) is a cluster platform that allows unmodified OpenCL applications to transparently utilize many OpenCL devices in a cluster, as if all the devices are on the local computer. The latest update includes one security fix, bug fixes and the addition of SuperCL special registry, allowing SuperCL programs to read the time in nano-seconds.

Version 2 adds support for ETC2 and EAC textures and conversion of legacy LUMINANCE* and INTENSITY* formats when loading in an OpenGL core context. It includes KTX loader tests for OpenGL ES 3.0 and OpenGL 3.3. In addition a couple of nasty bugs have been fixed including one in the KTX writer where image rows were not padded to 4 bytes as required by the spec. Complete details of the changes are located in the OpenGL ES SDK. A new version of toktx has also been released. New features are ability to create KTX files with textures in sized internal formats and defaulting to RED and RG formats for 1 and 2 channel textures. Naturally it incorporates the bug-fixed writer from libktx. Visit the KTX home page to download these tools.
