Release Highlights

Easier Application Porting

  • Share GPUs across multiple threads
  • Use all GPUs in the system concurrently from a single host thread
  • No-copy pinning of system memory, a faster alternative to cudaMallocHost()
  • C++ new/delete and support for virtual functions
  • Support for inline PTX assembly
  • Thrust library of templated performance primitives such as sort, reduce, etc.
  • NVIDIA Performance Primitives (NPP) library for image/video processing
  • Layered Textures for working with same size/format textures at larger sizes and higher performance

Faster Multi-GPU Programming

  • Unified Virtual Addressing
  • GPUDirect v2.0 support for Peer-to-Peer Communication

New & Improved Developer Tools

  • Automated Performance Analysis in Visual Profiler
  • C++ debugging in CUDA-GDB for Linux and MacOS
  • GPU binary disassembler for Fermi architecture (cuobjdump)
  • Parallel Nsight 2.0 now available for Windows developers with new debugging and profiling features.

Support for XP on notebooks is being phased out and is therefore not available for this release. Please refer to the Release Notes and Getting Started Guides for more information.
