Contains the size of the workgroup operated on by a compute shader.
In the compute language,gl_WorkGroupSizecontains the size of a workgroup declared by a compute shader. The size of the work group in the X, Y, and Z dimensions is stored in the x, y, and z components ofgl_WorkGroupSize. The values stored ingl_WorkGroupSizematch those specified in the required
local_size_y , and
local_size_z layout qualifiers for the current shader. This value is constant so that it can be used to size arrays of memory that can be shared within the local work group.
