A Snoop Filter for use in a multi-node processor system including different nodes of multiple processors and corresponding processor caches is provided with a Pseudo Least-Recently-Used (PLRU) replacement algorithm to identify a least-recently-used (PLRU) line from the plurality of lines in the cache array for update to reflect lines that are replaced in the processor caches.
