Transactions

Transactions. In the next few lectures we motivate the need for transactions then study them in detail From a single operation on a data object in a concurrent system, we extend to: Composite operations: in main memory, and with persistent memory

Synchronization

Synchronization. Clock Synchronization In a centralized system time is unambiguous. In a distributed system agreement on time is not obvious . When each machine has its own clock, an event that occurred after another event may be assigned an earlier time. Physical clocks.

Time and Clocks

Time and Clocks. uses of time in distributed systems: time-based algorithms (e.g. in security) distributed make gathering event traces for debugging proving or disproving causality (insider trading) common element: need to know in which order events happened. Absolute Time.
