Page 22 of OpenMP 5.0 specification (Lines 13/14): When any thread encounters a simd construct, the iterations of the loop associated with the construct may be executed concurrently using the SIMD lanes that are available to the thread This is the Execution Model. The word here is "may" i.e., not "must". Declare simd is not explicitly mentioned here, but requiring
