Release Notes

The source code with submodules can be downloaded directly from the following link:
http://arrayfire.com/arrayfire_source/arrayfire-full-3.2.0.tar.bz2

Major Updates

  • Added Unified backend
    • Allows switching backends at runtime
    • Read [Unified Backend](ref unifiedbackend) for more.
  • Support for 16-bit integers (\ref s16 and \ref u16)
    • All functions that support 32-bit interger types (\ref s32, \ref u32),
      now also support 16-bit interger types

Function Additions

  • Unified Backend
    • \ref setBackend() - Sets a backend as active
    • \ref getBackendCount() - Gets the number of backends available for use
    • \ref getAvailableBackends() - Returns information about available backends
    • \ref getBackendId() - Gets the backend enum for an array
  • Vision
    • \ref homography() - Homography estimation
    • \ref gloh() - GLOH Descriptor for SIFT
  • Image Processing
    • \ref loadImageNative() - Load an image as native data without modification
    • \ref saveImageNative() - Save an image without modifying data or type
  • Graphics
    • \ref af::Window::plot3() - 3-dimensional line plot
    • \ref af::Window::surface() - 3-dimensional curve plot
  • Indexing
    • \ref af_create_indexers()
    • \ref af_set_array_indexer()
    • \ref af_set_seq_indexer()
    • \ref af_set_seq_param_indexer()
    • \ref af_release_indexers()
  • CUDA Backend Specific
    • \ref setNativeId() - Set the CUDA device with given native id as active
      • ArrayFire uses a modified order for devices. The native id for a
        device can be retreived using nvidia-smi
  • OpenCL Backend Specific
    • \ref setDeviceId() - Set the OpenCL device using the clDeviceId

Other Improvements

  • Added \ref c32 and \ref c64 support for \ref isNaN(), \ref isInf() and \ref iszero()
  • Added CPU information for x86 and x86_64 architectures in CPU backend's \ref info()
  • Batch support for \ref approx1() and \ref approx2()
    • Now can be used with gfor as well
  • Added \ref s64 and \ref u64 support to:
    • \ref sort() (along with sort index and sort by key)
    • \ref setUnique(), \ref setUnion(), \ref setIntersect()
    • \ref convolve() and \ref fftConvolve()
    • \ref histogram() and \ref histEqual()
    • \ref lookup()
    • \ref mean()
  • Added \ref AF_MSG macro

Build Improvements

  • Submodules update is now automatically called if not cloned recursively
  • Fixes for compilation on Visual Studio 2015
  • Option to use fallback to CPU LAPACK
    for linear algebra functions in case of CUDA 6.5 or older versions.

Bug Fixes

Documentation Updates

  • Improved tutorials documentation
    • More detailed Using on [Linux](ref using_on_windows), [OSX](ref using_on_windows),
      [Windows](ref using_on_windows) pages.
  • Added return type information for functions that return different type
    arrays

New Examples

  • Graphics
    • [Plot3](ref plot3.cpp)
    • [Surface](ref surface.cpp)
  • [Shallow Water Equation](ref swe.cpp)
  • [Basic](ref basic.cpp) as a Unified backend example

Installers

  • All installers now include the Unified backend and corresponding CMake files
  • Visual Studio projects include Unified in the Platform Configurations
  • Added installer for Jetson TX1
  • SIFT and GLOH do not ship with the installers as SIFT is protected by
    patents that do not allow commercial distribution without licensing.
