This paper introduces the doubly-linked list (DLL) protocol for distributed shared memory (DSM) multiprocessor systems. The protocol makes use of two linked lists to keep track of valid copies of pages in the system, thus eliminating the use of copysets. Simulation studies show that the DLL protocol achieved considerable speed-up for common mathematical problems including a linear equations solver and a matrix multiplier. Performance improvement of up to 51.9% over the dynamic distributed manager algorithm is obtained. Further improvement and possible modification of the protocol are also discussed
