 4SLIT - System Locality Information Table
 5========================================

 7The system locality information table provides "abstract distances" between
 8accessor and memory nodes.  Node without initiators (cpus) are infinitely (FF)
 9distance away from all other nodes.

11The abstract distance described in this table does not describe any real
12latency of bandwidth information.
