LLVM/Clang release 9.0 with experimental support of C++ for OpenCL

​LLVM Clang 9.0 has been released and is now available for download. This is the first release to contain experimental support of C++ for OpenCL language mode in Clang. More details can be found in the Clang documentation. This new support will be discussed at the LLVM Developers meeting (October 2019) at the From C++ for OpenCL to C++ for accelerator devices talk by Khronos Member Anastasia Stulova.

A unified programming model offers enterprises and OEMs a cost-effectively way to take advantage of the growing diversity of processor platforms, letting companies share their source code investment across vendors and architectures. Enter oneAPI from Intel, which aims to revolutionize application development through a unified, open development model to simplify programming across processors. Intel built upon C++, and SYCL from The Khronos Group had some really good constructs that they thought provided a very good starting point. Intel extended and improved it to achieve the goals that they wanted to achieve. Most of the DPC++ extensions will eventually be synced upstream into SYCL.

​Last week saw the release of Vulkan 1.1.123. The release sees four issues from GitHub addressed and several Khronos internal issues fixed. Two new extensions have also be included: VK_KHR_shader_subgroup_extended_type: enables the Non Uniform Group Operations in SPIR-V to support 8-bit integer, 16-bit integer, 64-bit integer, 16-bit floating-point, and vectors of these types, and VK_GOOGLE_user_type: allows use of the SPV_GOOGLE_user_type extension in SPIR-V shader modules.

Alternatives to C++ Function Pointers in SYCL using Function Objects

In C++, especially in modern C++, function pointers are a legacy feature from the C language but they still exist in some code bases. SYCL does not provide support for function pointers as this is a limitation posed by the design of OpenCL v1.2 which is the basis of the current SYCL v1.2.1 definition. The good news is that we can use modern C++ to implement a solution that can be used with SYCL. Learn how to do this with examples from Codeplay.

Heterogeneous-Compute Interface for Portability (HIP) is a runtime API and a conversion tool to help make CUDA programs more portable. It was originally contributed by AMD to the open source community with the intention to ease the effort of making CUDA applications also work on AMD’s ROCm platform.

While AMD and NVIDIA share the vast majority of the discrete GPU market, it is useful to make this “CUDA portability enhancement route” available to an even wider set of platforms. Since the Khronos OpenCL standard remains the most widely adopted cross-platform heterogeneous programming API/middleware, it is interesting to study whether HIP could be ported on top of it, expanding its scope potentially to all OpenCL supported devices. We in Customized Parallel Computing group, Tampere University, Finland, are happy to announce that to have worked on such a tool, known as HIPCL, for some time and it’s now published and available in Github.

The first release of HIPCL is a proof-of-concept, but is already useful for end-users. It can run most of the CUDA examples in the HIP repository and the list of supported CUDA applications will grow steadily as we add new features.

On September 19 at AutoSens Brussels, Stephane Strahm of Kalray will be joining other attendees to discuss options for addressing the increasingly complex challenges facing automotive vision system engineers. Pushed by developments in markets such as Advanced Driver Assistance Systems (ADAS) and autonomous vehicles, maintaining component interoperability in increasingly complex vehicle subsystems is proving to be a big obstacle.
