Assess students' ability to analyze and compare snooping cache-coherence protocols (MESI and MOESI) in multicore processors. The quiz will test understanding of protocol states and transitions (M/E/S/I/O), coherence message types, owner/forwarding behavior, and how these mechanisms affect latency, bandwidth, and scalability. Tasks may include interpreting small execution traces or state diagrams for read/write hits and misses, reasoning about cache-to-cache transfers and invalidations, identifying effects of false sharing, and evaluating trade-offs versus directory-based designs and write policies. Problems require qualitative and simple quantitative analysis of performance and design choices.
