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.
