WebThis optimistic execution allows CoNDA to gather information on the memory accesses … WebJun 10, 2024 · One approach to reduce PIM coherence traffic is to apply coarse-grained coherence. For example, we can maintain a single coherence entry for all of the PIM data. Unfortunately, this can still incur high overheads, as the processor must flush all of the dirty cache lines within the PIM data region every time the PIM core acquires permissions ...

When clients in a system maintain caches of a common memory resource, problems may arise with incoherent data, which is particularly the case with CPUs in a multiprocessing system.
