Clock Algorithm Explained. a vector clock is a data structure used for determining the partial ordering of events in a distributed system and detecting causality. instead, we can use logical clocks to create a partial or total ordering of events. it is a page replacement algorithm. The operating system clears the bits from time to time in. Keep use bit for each page frame, hardware sets the appropriate bit on every memory reference. It is easy to understand, moderately efficient to implement and lamport’s logical clock was created by leslie lamport. clock algorithm key idea: It is a procedure to determine the order of events occurring. This article explores the concept of and an implementation of the logical clocks invented by. Implicit in this algorithm is that it is better to remove a modified page that has not been referenced in atleast one clock tick than a clean page that is in heavy use. It provides a basis for the more advanced vector clock algorithm. Due to the absence of a global clock in a distributed operating system lamport logical clock is needed. Rotate through pages until we find one that hasn’t been referenced since the last time we checked it. clock is just a simpler (and slightly faster) implementation of a fifo where you keep a circular linked list.
