Challenge Problems
Push your limits with challenges.
Question 1
Consider 3 processes A, B, and C with the following events and timestamps: A1: 1, A2: 2, B1: 1, C1: 1. If A sends a message to B after A1 and before A2, what can you deduce about their timestamps?
๐ก Hint: Think about how the sending event influences B's clock.
Question 2
You have a system with 4 processes. Process A's vector timestamp is [2,0,1,3] and Process B's is [1,2,0,2]. Determine their causal relationship.
๐ก Hint: Compare the vectors for magnitude.
