--- Comment #2 from Stephane Chevigny <stephane.chevi...@polymtl.ca> ---
The expected output:
value[i].x (= gl_GlobalInvocationID.x ;) should be equal to value[i].y and
value[i].w (= gl_WorkGroupID.x * gl_LocalGroupSizeARB.x +
gl_LocalInvocationID.x;) for all indices i according to spec. With the
parameter I gave to glDispatchComputeGroupSizeARB, the divergence of the result
happen after the indice i = 63 on my computer. So value[i].x = value[i].z
(=gl_LocalInvocationID.x;) instead.
So on my computer, gl_GlobalInvocationID.x appear to be only equal to
gl_LocalInvocationID.x notgl_WorkGroupID.x * gl_LocalGroupSizeARB.x +
gl_LocalInvocationID.x or I misread the spec.
