' This question is partially answered in this article by presenting a group mutual exclusion algorithm using fetch-and-increment instructions. The algorithm is simple and scalable. 展开▼ 机译:组互斥(GME)问题(也称为房间同步问题)出现在需要并发数据共享的各种实际应用中。组互斥旨在实现对共享资源(...
In another aspect, new synchronization primitives FetchAndIncrementBounded (Counter, Bound) and FetchAndDecrementBounded (Counter, Bound) are implemented. These primitives can be implemented in hardware and thus promise a very fast throughput for queues, stacks and double-ended queues.Chen, Dong...
Elements of Datapath for the fetch and increment The first element we need: a memory unit to store the instructions of a program and supply instructions given an address. The program counter (PC), which is a register that holds the address of the current instruction. Lastly, we will need a...
采用排队锁和fetch_and_increment原语重新实现栅栏同步,并将它们分别与采用旋转锁实现的栅栏同步进行性能比较。请帮忙给出正确答案和分析,谢谢!

A Fetch&Inc object stores a non-negative integer and supports a single operation, fi, that returns the value of the object and increments it. Such objects are used in many asynchronous shared memory algorithms, such as renaming, mutual exclusion, and barrier synchronization. We present an ...
