WaveGetNumWaves

Description

Returns the number of waves (subgroups) in the current workgroup. Equivalent to GLSL gl_NumSubgroups.

On GLSL and SPIR-V this lowers to gl_NumSubgroups / BuiltIn NumSubgroups, which are restricted to compute-class execution models (compute, mesh, amplification); using it from any other stage is a capability error.

Signature

uint WaveGetNumWaves();

Availability and Requirements

Defined for the following targets:

hlsl

Available in all stages.

glsl

Available in stages: amplification, mesh, compute.

cuda

Available in all stages.

metal

Available in all stages.

wgsl

Available in all stages.

spirv

Available in stages: amplification, mesh, compute.

Requires capabilities: spvGroupNonUniform, spvMeshShadingEXT.
