11a. Performance of DSM systems. Distributed shared memory systems combine the programming models of shared memory systems, and the scalability of distributed systems. However, since DSM systems need extra coordination between software layer and underlying hardware, achieving good performance could be a big challenge. The factors that harm the performance could be the overhead to maintain cache coherence, memory consistency, and the latency of interconnections. Please further explore the factors that can affect the performance of DSM systems, and the improvements that have been made on the existing systems.
