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.
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.
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.”
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.
Codeplay’s Offload for OpenCL is a tool-set built on top of OpenCL allowing developers to accelerate performance using C++ for any OpenCL supported GPU. It is bundled with a number of kernel library components which can be used to help build C++ based programming models for GPUs.
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.
AMDs Erwin Couman presentation on accelerating game physics heterogeneous systems using OpenCL are available on Github for download. Sample videos showing rigid body work, broadphase benchmarks, gDEBugger and Bullet Physics library are available on his YouTube channel.
CLOGS is a library for higher-level operations on top of the OpenCL C++ API. It is designed to integrate with other OpenCL code, including synchronization using OpenCL events.
Currently two operations are supported: radix sorting and exclusive scan. Radix sort supports all the unsigned integral types as keys, and all the built-in scalar and vector types suitable for storage in buffers as values. Scan supports all the integral types. It also supports vector types, which allows for limited multi-scan capabilities.
The Khronos Group has posted several presentation slide sets online from SIGGRAPH Asia 2011. Included are slides sets covering KITE, OpenGL, OpenGL ES, OpenGL SC, OpenVG, OpenMAX, OpenSL ES, StreamInput, WebGL and WebCL.
Presentation slides from the Khronos Asian Tour have been posted on the Khronos Group website. Slides include those from the Khronos Games Conference DevU and the OpenCL 1.2 press conference. Khronos Members will have access to additional slides from the Korean and Japanese member meetings.
The Lightweight Java Game Library (LWJGL) is a solution aimed directly at professional and amateur Java programmers alike to enable commercial quality games to be written in Java. LWJGL provides developers access to high performance crossplatform libraries such as OpenGL, OpenCL, and OpenAL, allowing for state of the art 3D games and 3D sound. Additionally LWJGL provides access to controllers such as Gamepads, Steering wheel and Joysticks.
libCL is an open-source parallel algorithm library written in C++ and OpenCL, released under the Apache 2.0 license. Based on a thin layer of wrapper classes for OpenCL and OpenGL are implementations of parallel algorithms ranging from simple primitives such as sorting, searching and algebra to complex systems of algorithms for computational research and visualization. libCL emerged out of OpenCL Studio, and as such integrates well with the development environment and its rich prototyping and visualization capabilities.
OpenCL™ Common Runtime for Linux® on x86 architecture is an OpenCL layered product that improves the OpenCL programming experience by alleviating the programmer from the burden of managing multiple OpenCL platforms and duplicated resources. It is a dynamic shared library that resides between an OpenCL application and one or more OpenCL implementations, such as those developed by AMD and NVIDIA® .
The Common Runtime supports all of the OpenCL v1.1 APIs in a single OpenCL platform consisting of all devices provided by the underlying implementations. This technology provides an integrated environment that can improve application portability as well as simplifying multi-device programming. The Common Runtime has been tested on the IBM System x® iDataPlex™ dx360 M3 with at least one NVIDIA® Tesla™ M2050 running Red Hat Enterprise Linux 5.5. In addition, OpenCL v1.1 implementations from AMD and NVIDIA were used in conjunction with the OpenCL Common Runtime.
Two major changes in the latest version of GLM include GLSL 4.10 packing functions and == and != operators for all types.
