Description
This extension enables support for a new class of
group operations on subgroups via the
GL_NV_shader_subgroup_partitioned
GLSL extension and
SPV_EXT_shader_subgroup_partitioned
SPIR-V extension.
Support for these new operations is advertised via the
VK_SUBGROUP_FEATURE_PARTITIONED_BIT_EXT bit.
Note that there is not a new GLSL extension since
SPV_EXT_shader_subgroup_partitioned is compatible with
SPV_NV_shader_subgroup_partitioned, so the
GL_NV_shader_subgroup_partitioned GLSL extension can still be used.
This extension requires Vulkan 1.1, for general subgroup support.
