=== Description

This extension enables support for a new class of
<<shaders-group-operations, group operations>> on <<shaders-scope-subgroup,
subgroups>> via the
https://github.com/KhronosGroup/GLSL/blob/master/extensions/nv/GL_NV_shader_subgroup_partitioned.txt[`GL_NV_shader_subgroup_partitioned`]
GLSL extension and
{spirv}/NV/SPV_NV_shader_subgroup_partitioned.html[`SPV_NV_shader_subgroup_partitioned`]
SPIR-V extension.
Support for these new operations is advertised via the
ename:VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV bit.

This extension requires Vulkan 1.1, for general subgroup support.
