## 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_NV_shader_subgroup_partitioned` SPIR-V extension. Support for these new operations is advertised via the `VK_SUBGROUP_FEATURE_PARTITIONED_BIT_NV` bit.

This extension requires Vulkan 1.1, for general subgroup support.
