Synchronous N-processor systems with M shared memories are considered. Memory interference is modeled for processor request rates between 0 and 1 per memory cycle. Two probability-based models and one queueing-based model are summarized from prior literature. A new steady-state flow model is introduced. This steady-state model is most accurate overall. The queueing model is somewhat more accurate when request rate is near 1, and M and N are large. Accuracy is established with respect to probabilistic simulation. Additional related models are described.
