Libra 1.2 includes new OpenCL back end

June 8th, 2010

GPU Systems LogoGPU Systems has added an OpenCL back end implementation to its Libra Technology compiler and runtime architecture. Libra version 1.2 now supports x86/x64, OpenGL/OpenCL and CUDA compute back ends. The OpenCL back end generates dynamic code specifically for AMD GPUs. Also, the CUDA back end generator has been enhanced with Fermi capabilities and this new release brings full BLAS 1,2,3 matrix, vector, dense, sparse, complex, single/double standard math library functionality and access through a standard C programming interface & library. The high-level approach of the Libra API enables developers to easily extend existing high-level functionality from their favorite programming language.

ATI Stream Profiler v1.3 Released

May 20th, 2010

Advanced Micro Devices (AMD) recently released ATI Stream Profiler version 1.3. ATI Stream Profiler is a Microsoft® Visual Studio® integrated runtime profiler that gathers performance data from the GPU as your OpenCL™ application runs. This information can then be used by developers to discover where the bottlenecks are in their OpenCL™ application and find ways to optimize their application’s performance.

Features of the tool include:

  • Measure the execution time of an OpenCL kernel
  • Query the hardware performance counters on ATI Radeon graphics cards
  • Display the memory traffic from and to GPU
  • Compare multiple runs (sessions) of the same or different programs
  • Store the profile data for each run in a csv file
  • Display the IL and ISA (hardware disassembly) code of the OpenCL kernel

ATI Stream SDK 2.0 is the first production SDK for both AMD GPUs and x86 CPUs. This release supports a wide range of ATI graphics processors, including the new ATI Radeon HD 5970, and provides support for OpenCL ICD (Installable Client Driver), atomic functions for 32-bit integers, a Microsoft Visual Studio 2008-integrated ATI Stream Profiler performance analysis tool, and other robust features. Preview support for upcoming features include OpenCL and Microsoft DirectX 10 interoperability, and double-precision floating point basic arithmetic in OpenCL C kernels.

AMD STREAM SDK v2.0 beta Supports OpenCL on CPUs and GPUs

October 19th, 2009

AMD’s STREAM SDK v2.0 beta4 is the first release of the STREAM SDK with OpenCL support on CPUs and GPUs. The OpenCL implementation is certified OpenCL 1.0 conformant by the Khronos group. Supported platforms are Windows XP, Vista and Windows 7, and a number of Linux distributions, all in 32 and 64-bit. The implementation supports AMD and Intel multicore CPUs, as well as the two latest GPU generations from AMD.

The STREAM SDK as well as documentation and further information is available on AMD’s developer website.

ATI Radeon™ HD 5800 Series Announced By AMD

October 1st, 2009

AMD announced its latest ATI Radeon™ series of graphics cards on September 23rd.  The new GPUs boast up to 2.72 GFLOP/s of single-precision floating point throughput, along with DirectX® 11 graphics (including DirectCompute) and OpenCL 1.0 support.

From the press release:

AMD (NYSE: AMD) today launched the most powerful processor ever created1, found in its next-generation graphics cards, the ATI Radeon™ HD 5800 series graphics cards, and the world’s first and only to fully support Microsoft DirectX® 112, the new gaming and compute standard shipping shortly with Microsoft Windows® 7operating system. Boasting up to 2.72 TeraFLOPS of compute power, the ATI Radeon™ HD 5800 series effectively doubles the value consumers can expect of their graphics purchases, delivering twice the performance-per-dollar of previous generations of graphics products.3 AMD will initially release two cards: the ATI Radeon HD 5870 and the ATI Radeon HD 5850, each with 1GB GDDR5 memory. With the ATI Radeon™ HD 5800 series of graphics cards, PC users can expand their computing experience with ATI Eyefinity multi-display technology, accelerate their computing experience with ATI Stream technology, and dominate the competition with superior gaming performance and full support of Microsoft DirectX® 11, making it a “must-have” consumer purchase just in time for Microsoft Windows® 7 operating system.
