'These are 2 big steps forwards to enable software developers to embrace heterogeneous platforms and Codeplay is actively involved in developing for both already.'

OpenCL 2.0 will allow applications to process more complex data and algorithms in parallel than was possible in previous standards, while OpenCL SPIR will allow a variety of different programming languages to be compiled directly into OpenCL code for heterogeneous systems,' said Andrew Richards, CEO of Codeplay. 'These 2 new OpenCL specifications will allow software developers to accelerate a much wider variety of applications on a greater range of devices than previously possible. Khronos has contributed open source patches for Clang 3.2 to enable SPIR code generation. OpenCL SPIR will enable consumption of code from third party compiler front-ends for alternative languages, such as C++, and is based on LLVM 3.2.

It enables application developers to avoid shipping kernel source and to manage the proliferation of devices and drivers from multiple vendors.

'SPIR' stands for Standard Portable Intermediate Representation and is a portable non-source representation for OpenCL 1.2 device programs. In addition, the OpenCL Working Group also today released the OpenCL SPIR 1.2 provisional specification for public review. OpenCL SPIR 1.2 Provisional Specification

Pipes are memory objects that store data organized as a FIFO and OpenCL 2.0 provides built-in functions for kernels to read from or write to a pipe, providing straightforward programming of pipe data structures that can be highly optimized by OpenCL implementers.ДЄndroid Installable Client Driver ExtensionД®nables OpenCL implementations to be discovered and loaded as a shared object on Android systems. Improved image support including sRGB images and 3D image writes, the ability for kernels to read from and write to the same image, and the creation of OpenCL images from a mip-mapped or a multi-sampled OpenGL texture for improved OpenGL interop.ДЄ subset of C11 atomics and synchronization operations to enable assignments in one work-item to be visible to other work-items in a work-group, across work-groups executing on a device or for sharing data between the OpenCL device and host. Host and device kernels can directly share complex, pointer-containing data structures such as trees and linked lists, providing significant programming flexibility and eliminating costly data transfers between host and devices.Дevice kernels can enqueue kernels to the same device with no host interaction, enabling flexible work scheduling paradigms and avoiding the need to transfer execution control and data between the device and host, often significantly offloading host processor bottlenecks.ДЇunctions can be written without specifying a named address space for arguments, especially useful for those arguments that are declared to be a pointer to a type, eliminating the need for multiple functions to be written for each named address space used in an application. Updates and additions to OpenCL 2.0 include: In addition to enabling application developers it is providing foundational, portable acceleration for middleware libraries, engines and higher-level programming languages that need to take advantage of heterogeneous compute resources including CPUs, GPUs, DSPs and FPGAs.' 'OpenCL continues to gather momentum on both desktop and mobile devices. The OpenCL 2.0 provisional specification and reference cards are available at 'The OpenCL working group has combined developer feedback with emerging hardware capabilities to create a state-ofвЂ“the-art parallel programming platform - OpenCL 2.0,' said Neil Trevett, chair of the OpenCL working group, president of the Khronos Group and vice president of mobile content at NVIDIA. The release of the specification in provisional form is to enable developers and implementers to provide feedback before specification finalization, which is expected within 6 months. As the foundation for these increased capabilities, OpenCL 2.0 defines an enhanced execution model and a subset of the C11 and C++11 memory model, synchronization and atomic operations.

OpenCL 2.0 is a significant evolution of the open, royalty-free standard that is designed to further simplify cross-platform, parallel programming while enabling a significantly richer range of algorithms and programming patterns to be easily accelerated. July 22nd 2013 вЂ“ SIGGRAPH - Anaheim, CA вЂ“ The Khronosв„ў Group today announced the ratification and public release of the OpenCLв„ў 2.0 provisional specification.
