Webb14 aug. 2024 · A timestamp is given to each critical section request using Lamport’s logical clock. Timestamp is used to determine priority of critical section requests. Smaller timestamp gets high priority over larger timestamp. The execution of critical section request is always in the order of their timestamp. Algorithm:

Time, Clocks, and the Ordering of Events in a Distributed System

Webb15 okt. 2011 · To synchronize logical clocks, Lamport defined a relationship called a prior occurrence. The expression a -> b is read as "a occurs before b". This relationship of occurrence can be seen in 2 situations: If 'a' and 'b' are events of the same process, and 'a' occurs before 'b', then a -> b is true. If 'a' is the event in which a process sends a ... WebbThe Lamport timestamp algorithm is a simple logical clock algorithm used to determine the order of events in a distributed computer system.

WebbLamport's Logical Clocks. People use physical time to order events. For example, we say that an event at 8:15 AM occurs before an event at 8:16 AM. In distributed systems, physical clocks are not always precise, so we can't rely on physical time to order events. Instead, we can use logical clocks to create a partial or total ordering of events.

Conceptually, this logical clock can be thought of as a clock that only has meaning in relation to messages moving between processes.
