What are the main challenges in shared memory models?

The main challenges include synchronization issues, data consistency, and scalability. Would you like to know more about any specific challenge?

Can you explain synchronization issues?

Synchronization issues arise when multiple processes access shared memory simultaneously, leading to race conditions and data corruption.

How can these synchronization issues be resolved?

They can be resolved using techniques like locks, semaphores, and barriers to ensure that only one process accesses the shared memory at a time.

What about data consistency?

Data consistency ensures that all processes have a coherent view of the data. Techniques like memory models and consistency protocols help maintain this.

What are some examples of consistency protocols?

Examples include Sequential Consistency, Causal Consistency, and Linearizability, each with different trade-offs in performance and complexity.
