This exercise examines a queue implementation (listing 3) whose enq() method does not have a linearization point. The queue stores its items in an items array, which for simplicity we will …

Feb 16, 2022 · Linearizability is a lesser-known, yet omnipresent property of a data registry in the context of read and write operations that might happen concurrently. This article aims to …

Outline 2 1.Feedback: Assignment 11 2.Recap: Linearizability 3.Recap: Java memory model 4.Recap: Software Transactional Memory (STM) 5.Assignment 12

Apr 24, 2025 · Example: Implementing strict consistency requires a complex distributed system design. Below is a simplified code example in Node.js to demonstrate how locks can be used …

Problem 1 AMP, p.66, Exercise 24: Sequential Consistency and Lineariz-ability (12 Points) Fig. 3.13: This history is linearizable. A sequential execution of the history's events that is a …

Oct 7, 2015 · In this terrible implementation, we can easily prove, for example, that the first line of enq is not a valid linearization point, by assuming that it is a linearization point, and then …

Consider this queue implementation whose enq() method does not have a linearization point. The queue stores its items in an items array, which for simplicity we will assume is unbounded. The …

Give an example of an execution that is quiescently consistent but not sequentially consistent, and another that is sequentially consistent but not quiescently consistent. The AtomicInteger …

•A concurrent execution is linearizable if •each operation has a linearization point during the operation, such that •if all operations appear to occur instantly at their linearization points, then …

— Examples: Concurrent Queue, AtomicInteger Linearizability • Assume that each method call takes effect “instantaneously” at some distinct point in time between its invocation and return. • …
