Change log for June 18, 2018 Vulkan 1.1.78 spec update:

  * Update release number to 78.

Public Issues:

  * Change markup so parameter descriptions include links to structures,
    instead of just their names (public issue 697).
  * Resume publishing updated Vulkan 1.0 + KHR extensions and Vulkan 1.0 +
    all extensions versions of the specification (public issue 722).
  * Reapply fixes from public pull request 698 for
    `VK_ANDROID_external_memory_android_hardware_buffer`, which accidentally
    were reverted at some point (public pull request 724).
  * Fix undefined format valid usage statements for slink:VkImageCreateInfo
    in the presence of the
    `VK_ANDROID_external_memory_android_hardware_buffer` extension (public
    pull request 725).
  * Miscellaneous markup consistency fixes (public pull request 728).

Internal Issues:

  * When building specifications containing vendor extensions, add terms to
    the Khronos spec copyright specifying that the result is not a ratified
    specification (internal issue 739).
  * Change the value of the
    pname:maxDescriptorSetUpdateAfterBindUniformBuffers minimum limit to 72
    (6 times pname:maxPerStageDescriptorUpdateAfterBindUniformBuffers) in
    the <<features-limits-required, Required Limits>> table (internal issue
    1300).

Other Issues:

Change log for June 10, 2018 Vulkan 1.1.77 spec update:

  * Update release number to 77.

Public Issues:

  * Remove redundant asciidoctor ifdef in slink:VkDeviceCreateInfo valid
    usage statement (public pull request 718).

Internal Issues:

  * Require that the returned slink:VkMemoryRequirements::pname:alignment
    reflect the minimum alignment requirements for the buffer's usages, and
    make dynamic offset alignment valid usage more explicit for
    flink:vkBindBufferMemory and flink:vkCmdBindDescriptorSets (internal
    issue 1170).
  * Explicitly state that objects of type code:OpTypeImage,
    code:OpTypeSampler, and code:OpTypeSampledImage must not be stored to in
    the <<spirvenv-module-validation, Validation Rules within a Module>>
    section (internal issue 1262).
  * Clarify rules about validating descriptor set/binding against storage
    class and descriptor type in the <<spirvenv-module-validation,
    Validation Rules within a Module>> section, and add an anchor for and
    references to the <<interfaces-resources-storage-class-correspondence,
    Shader Resource and Storage Class Correspondence>> table (internal issue
    1266).
  * Use correct spelling of SPIR-V decoration code:NonWritable in several
    places (internal issue 1298).

Other Issues:

  * Update specification links to files in the old
    KhronosGroup/Vulkan-LoaderAndValidationLayers repository with
    corresponding links into the new repositories that replace it.
  * Move validity requirement for slink:VkSamplerCreateInfo into the valid
    usage block instead of the body text, and give it a VUID.
  * Use the full name of the "`style guide`" in a reference in the
    description of slink:vkGetPhysicalDeviceProperties, update the
    <<vulkan-styleguide, link to that document>>, and use the the full name
    in the registry index page.

3D-Tech News Around The Web / AMD GPU Services 5.2.0
« on: June 03, 2018, 03:04:47 PM »
We recently released AGS 5.2.0 and its associated documentation, adding some commonly requested functionality and fixing some bugs (of course!).
The major functionality is the addition of app registration for DirectX® 12. App registration lets you give more information about your game or application to our driver, which can then use that (ideally unique) information to better support the game or app if we need to make driver-side changes to help things run as efficiently and correctly as possible.

Change log for May 16, 2018 Vulkan 1.1.75 spec update:

  * Update release number to 75.

Github Issues:

  * Use Github handles (e.g. @handle) for contact information in vk.xml,
    when available (partial fix for public issue 630).
  * Add size invariance guarantee to slink:VkMemoryRequirements for
    buffer/image memory requirements (public issue 661).
  * Correct scope (conditional constructs) in valid usage statement for
    slink:VkBindImageMemoryInfo (public pull request 684).
  * Clean up minor markup issues and typos in the
    `VK_ANDROID_external_memory_android_hardware_buffer` extension appendix
    (public pull request 698).
  * Modify registry processing script to avoid irrelevant warnings of benign
    enumerant redefinitions (public pull request 705).
  * Fix some duplicate words and some misspelled "`stagess`" (public pull
    request 712)

Internal Issues:

  * Enable continuous integration tests on the internal Khronos gitlab
    server by adding a .gitlab-ci.yml file. Note: this does not implement CI
    on the public Github repository (internal issue 408).
  * Add link from description of depth clamping in the <<fragops-depth,
    depth test>> section to the
    slink:VkPipelineRasterizationStateCreateInfo::pname:depthClampEnable
    parameter which enables it, making it easily searchable / findable
    (internal issue 1125).
  * Clarify that arrays of arrays of descriptors are not allowed in the
    <<interfaces-resources-descset, Descriptor Set Interface>> and
    <<interfaces-resources-setandbinding, DescriptorSet and Binding
    Assignment>> sections (internal issue 1192).
  * Comment out some redundant nested asciidoctor conditionals in the
    slink:VkImageViewCreateInfo valid usage block, and explain in all cases
    why the redundant conditional exist and are commented out (internal
    issue 1231).
  * Move a valid usage statement from slink:VkCommandPoolCreateInfo to the
    parent flink:vkCreateCommandPool, where the device queue is known
    (internal issue 1233).
  * Add new slink:VkBaseInStructure and slink:VkBaseOutStructure types which
    can be used by extensions and implementations for handling Vulkan
    sType/pNext style structures in a more generic way (internal issue
    1265).
  * Clarify that
    slink:VkAndroidHardwareBufferFormatPropertiesANDROID::pname:formatFeatures
    only applies to external-format images. Add references to this in valid
    usage statements that previously only referred to
    slink:VkFormatProperties (internal issue 1244).
  * Fix the description of elink:VkPipelineCreateFlagBits enumerant
    ename:VK_PIPELINE_CREATE_VIEW_INDEX_FROM_DEVICE_INDEX_BIT to match the
    name (internal issue 1279).
  * Add a NOTE to the <<interfaces-resources-setandbinding, DescriptorSet
    and Binding Assignment>> section making it clear that variables sharing
    a storage class may use identical descriptor set and bindings.
    Specifically state the sometimes misunderstood ability to have one or
    more differently typed image descriptors sharing a descriptor set and
    binding (internal SPIR-V issue 264).
  * Make DynamicIndexing features and capabilities also control the
    uniformity of the descriptor used in memory access instructions in the
    <<interfaces-resources-descset, Descriptor Set Interface>> section. This
    makes them also apply to variable_pointer usage, which can bypass the
    array indexing operation (internal SPIR-V issue 289).

Other Issues:

  * Correct flink:vkCmdBlitImage limitations on cubic blits to be 2D only,
    not 3D.
  * Update valid usage statements for slink:VkRenderPassCreateInfo and
    slink:VkInputAttachmentAspectReference.
  * Move YCbCr-related VU statements from slink:VkDescriptorImageInfo to
    slink:VkWriteDescriptorSet, where all needed information is known, and
    remove redundant statements.
  * Move SPIR-V restriction that images be of either sampled or storage
    types from the <<interfaces-resources-descset, Descriptor Set
    Interface>> section to the <<spirvenv-module-validation, Validation
    Rules within a Module>> section of the SPIR-V appendix.

The release notes for the CUDA Toolkit can be found online at http://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html.
  2.1. General CUDA 
  • Improved kernel launch latency (using the <<< >>> syntax and the cudaLaunchKernel API) for both multithreaded and multi-GPU code by up to a factor of 2 compared to CUDA 9.0.
  • Added support for unified memory with address translation services (ATS) on IBM POWER9.
  • Added arithmetic operators for the __half2 data type and a volatile assignment operator for the __half data type.
  • Added version 6.2 of the Parallel Thread Execution instruction set architecture (ISA). For details about new instructions (activemask, FP16, and atomics) and deprecated instructions, see Parallel Thread Execution ISA Version 6.2 in the PTX documentation.
  • IPC functionality is now supported on Windows.
  • Added P2P write and read bandwidth and latency metrics to the p2pBandwidthLatencyTest sample.
  • Thrust now uses CUB v1.7.5.
  • Added some performance optimizations in Thrust for the templated complex type.
  • Added support for new operating systems. For a list of operating systems supported by CUDA, see the following information in the installation guides:
  • Changed CUDA_DEVICE_ORDER==FASTEST_FIRST to enumerate GPUs in descending order of performance.
  • Added a new driver API cuStreamGetCtx to retrieve the context associated with a stream. This API is primarily used by the multidevice cooperative launch runtime API to ensure that the specified function's module is loaded in the right context.
  • Added support for full core dump generation on Linux by using named pipes for MPS-based CUDA applications and CUDA applications that are not based on MPS.
  • Added these new helper APIs for cooperative groups:
    • grid_dim() to get the 3-dimensional grid size
    • block_dim() to get the 3-dimensional block size
