Release Highlights
  • OpenCL v1.0 Conformant GPU drivers for all CUDA-enabled GPUs
    • Certified conformance by the Khronos OpenCL Working Group on 12 June 2009
    • Includes support for OpenCL Images and atomics, which enable significant acceleration across many image processing disciplines. For example Medical Imaging, Video Transcoding applications, Machine Vision, Facial Detection and Recognition and more via the following extensions:
      • cl_khr_byte_addressable_store
      • cl_khr_global_int32_base_atomics
      • cl_khr_global_int32_extended_atomics
      • cl_khr_local_int32_base_atomics
      • cl_khr_local_int32_extended_atomics
  • OpenCL Visual Profiler leverages performance instrumentation in NVIDIA's OpenCL drivers and hardware performance signals designed into NVIDIA GPUs. This powerful analysis tool provides developers with insight into performance bottlenecks and opportunities via these key features:
    • Profiling of actual hardware signals, kernel efficiency, and instruction issue rate
    • Timing of memory copies between system memory and GPU dedicated memory
    • Customizable graphs to help developers focus in on problem areas
    • Basic auto-analysis to reveal warp serialization problems
    • Easy import/export to CSV for custom analysis
  • Support for multi-GPU performance scaling has been added to most of the OpenCL code samples, and several new code samples have been added as well, including:
    • oclMedianFilter
    • oclFDTD3d
    • oclRadixSort
    • oclMersenneTwister
    • oclSemirandomGenerator
  • OpenCL Best Practices Guide, designed to help developers using OpenCL on the CUDA architecture implement high performance parallel algorithms and understand best practices for GPU Computing. Chapters on the following topics and more are included in the guide:
    • Heterogeneous Computing with OpenCL
    • Performance Metrics
    • Memory Optimizations
    • NDRange Optimizations
    • Instruction Optimizations
    • Control Flow
    • Performance Optimization Strategies
The drivers and SDK code samples in this release are compatible with with the publicly available CUDA Toolkit 2.3, available at www.nvidia.com/cuda.
