How can I optimize cache coherence in my multi-core system?
To optimize cache coherence, consider using a directory-based protocol or implementing a MESI protocol to reduce traffic.
What are the benefits of using a directory-based protocol?
A directory-based protocol reduces the need for broadcast messages, improving scalability and reducing latency.
Are there any trade-offs I should be aware of?
Yes, while it improves scalability, it can introduce complexity in the directory management and may require more memory.
How does MESI compare to other protocols?
MESI is efficient for many workloads, but other protocols like MOESI can provide better performance for specific scenarios.
