* Update release number to 124.
Github Issues:
* Fix Makefile SPECREMARK macro to work when not building in a git tree
(public issue 992).
* Ignore pname:aspectMask for unused attachments in
slink:VkSubpassDescription2KHR valid usage statements (public pull
request 1028).
* Minor markup / spelling fixes (public pull requests 1035, 1045).
Internal Issues:
* Fix markup in Valid Usage statement for slink:VkCreateFramebuffer
(internal issue 1823).
* Add a new <<synchronization-signal-operation-order, _signal operation
order_>> section to the synchronization chapter which describes in
detail the ordering guarantees provided by the API between fence and
semaphore signal operations (internal merge request 3368).
* Move generated `appendix/meta/` files into the Makefile GENERATED
directory (internal merge request 3381).

This extension adds support for using cooperative matrix types in SPIR-V.
|
|
Cooperative matrix types are medium-sized matrices that are primarily
|
|
supported in compute shaders, where the storage for the matrix is spread
|
|
across all invocations in some scope (usually a subgroup) and those
|
|
invocations cooperate to efficiently perform matrix multiplies.
|
|
|
|
Cooperative matrix types are defined by the
|
|
{spirv}/NV/SPV_NV_cooperative_matrix.html[`SPV_NV_cooperative_matrix`]
|
|
SPIR-V extension and can be used with the
|
|
https://github.com/KhronosGroup/GLSL/blob/master/extensions/nv/GLSL_NV_cooperative_matrix.txt[`GL_NV_cooperative_matrix`]
|
|
GLSL extension.
|
|
|
|
This extension includes support for enumerating the matrix types and
|
|
dimensions that are supported by the implementation.

|
|
|
(1) What matrix properties will be supported in practice?
|
|
|
|
RESOLVED: In NVIDIA's initial implementation, we will support:
|
|
|
|
* AType = BType = fp16 CType = DType = fp16 MxNxK = 16x8x16 scope =
|
|
Subgroup

|
* AType = BType = fp16 CType = DType = fp16 MxNxK = 16x8x8 scope =
|
|
Subgroup
|
|
* AType = BType = fp16 CType = DType = fp32 MxNxK = 16x8x16 scope =
|
|
Subgroup
