We present a new arrangement of directory bits called the segment directory to improve directory storage effi-ciency: a segment directory can point to several shar-ing processors with almost the same number of bits as the pointer which can point to only one. Many directory overflows can be eliminated by using the segment direc-tory element in place of the pointer in the limited directory schemes. Also, the segment directory can be implemented without introducing additional hardware overhead and pro-tocol complexity. The detailed execution-driven simulations show that the segment directory always does better than the pointer and eliminates many directory overflows by up to 85%. The resulting improvement in bandwidth and execu-tion time is an...
