Description

In the compute language,
gl_WorkGroupSize
contains 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 of
gl_WorkGroupSize
. The values stored in
gl_WorkGroupSize
match those specified in the required local_size_x , 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.
