ABSTRACT:
A method for increasing cache concurrency in a multiprocessor system. In a multiprocessor system having a plurality of processors each having a local cache in order to increase concurrency the directory entry for a line in local cache will be assigned an LCH bit for locally changed status. If the last cache to hold the line had made a change to it this bit will be set on. If not, the bit will be off and thereby allow the receiving or requesting cache to make change to the line without requiring a main storage castout.
