priority inversion meaning in Chinese
优先转置
Examples
- Priority inversion arises when a higher - priority task is forced to wait an indefinite period of time for a lower - priority task to complete
优先级反转是指一个任务等待比它优先级低的任务释放资源而被阻塞,如果这时有中等优先级的就绪任务,阻塞会进一步恶化。优先级继承技术可用来解决优先级反转问题。 - The most difficult task of the design is to arrange the privilege of all task to ensure the system ' s response to external real - time event timely , to avoid the deadlock , to decrease the priority inversion and to enhance the ability of fault - tolerance
根据需求确定各个任务线程的优先级保证实时时间的及时响应以及如何避免死锁,减少优先级级倒置和提高系统的容错性是工作的难点。 - The rt - al provides consistent thread interface and identical thread scheduling model from the semantic aspect . what ' s the most important , priority inversion could be avoided by the rt - al . and the rt - al can also be optimized for network and i / o operations
实时基础设施提供一致的线程接口、相同的线程调度语义,并且能够避免线程互斥时发生优先级翻转,能够对网络和i / o进行实时优化。 - Particularly , it aims at the requirements to the priority and the schedule of the real - time system , exploits the real - time ability of thread library , and implements a fixed - priority based scheduling algorithm and a mutex with priority inheritance protocol which can avoid priority inversion and give much more predictability or determinism to real - time system
特别地,针对实时系统对线程优先级和调度的基本需求,开发了线程库的实时特性,实现了基于固定优先级的调度算法和支持优先级继承协议的锁机制,从而避免了优先级反转给实时系统带来的不可预测性。 - To deal with the difference on operating system level , this paper designs a thread - level algorithm based upon priority inheritance protocol to prevent priority inversion . a dynamic priority mapping and scheduling algorithm to achieve strict order is also presented . through analysis of multi - threaded execution order under fixed priority scheduling model , a multithreaded programming model with totally predicable execution order is proposed
针对各种操作系统的差异,本文提出了基于优先级继承协议的线程级防优先级翻转算法,提出了能够严格保序的动态优先级映射方法及相关的调度算法,通过研究固定优先级调度下的多线程执行顺序问题,本文还提出了一种执行顺序可预测的多线程程序设计模式。
