A dependency in a DO-loop whereby a result depends upon completion of the previous iteration of the loop Such dependencies inhibit vectorization For example: A(I) = A(I-1) + B(I) In a loop on I, this process would not be vectorizable on most vector computers without marked degradation in performance This is not an axiom or law, but rather is simply a fact resulting from current machine design
A computation in a loop in which the values produced in the current iteration depend on values produced in previous iterations A typical example is: DO I=1,N X(I)=X(I-1) + A(I) END DO
