• This Open VKL release adds support for Intel® Arc™ GPUs, Intel® Data Center
  GPU Flex Series and Intel® Data Center GPU Max Series through SYCL.
  • The SYCL support of Open VKL is in beta phase. Current functionality,
    quality, and GPU performance may not reflect that of the final product.
  • Open VKL CPU support in this release remains at Gold level,
    incorporating the same quality and performance as previous releases.
• API changes:
  • Handle types are now passed by pointer in the following APIs:
    • vklComputeSample*()
    • vklComputeGradient*()
    • vklGet*IteratorSize*()
    • vklInit*Iterator*()
    • vklIterate*()
  • vklLoadModule() has been removed; compile-time linkage to an Open VKL
    device implementation (cpu or gpu) is now required
  • Added vklInit() API, which must be called to initialize the library
  • VKL_FILTER_[TRILINEAR,TRICUBIC] are renamed to
    VKL_FILTER_[LINEAR,CUBIC]
  • VKLAMRMethod enum is now uint32_t
  • structuredSpherical volumes: the gridSpacing default now results in
    the volume occupying a full sphere
• Added new examples demonstrating GPU usage: vklExamplesGPU and
  vklTutorialGPU
• Superbuild updates to latest versions of dependencies
