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.ĭevice 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.įunctions 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-of–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 – SIGGRAPH - Anaheim, CA – The Khronos™ Group today announced the ratification and public release of the OpenCL™ 2.0 provisional specification. New generation of industry open standard for cross-platform parallel programming delivers increased flexibility, functionality and performance
