Problems solved by technology

As the number of threads increases, the problem will become more and more troublesome
[0005] In addition, the use of multi-core architecture in the existing data processing system, in order to take full advantage of the characteristics of multi-core CPU, will make it necessary to run multi-threads. Similarly, this will also increase the risk of downtime due to thread crashes
Large platforms with more CPU cores have more threads, and the problems caused by thread crashes are worse

Abstract

The invention provides a data processing system and method and device for resource recovery after thread crash. The method for resource recovery after thread crash comprises the steps that every record in a resource information record chart is traversed, wherein one record of the resource information record chart stores the resource metadata of one source and thread information of threads using the resource; the resource metadata of the resource used by the crashed thread are determined according to the traversal result; the resource metadata of the resource used by the crashed thread are inserted into a resource distribution queue so as to be redistributed to the thread. By means of the scheme, the resource information of the resource used by the crashed threads can be determined, the resource metadata of the resource used by the crashed thread are inserted into the resource distribution queue so as to be redistributed to the restarted thread, no high expense is caused to other threads in the system, the crashed thread and the corresponding resource can be restarted rapidly, the risk of system crash is reduced, and operating stability is improved.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a data processing system and a resource recovery method and device after a thread crashes. Background technique [0002] Thread is the smallest unit of program execution flow. A standard thread consists of a thread identifier (thread ID), a set of current instruction pointer registers and a stack. A thread itself does not own system resources, but only a few resources that are essential for running, but it can share all the resources owned by the process with other threads belonging to the same process. A thread is a single sequential flow of control in a program. Running multiple threads simultaneously in a single program to do different tasks is called multithreading. [0003] Data processing systems, including computers and data routing / forwarding devices, typically run multiple threads concurrently based on shared resources. Each thread includes an independent execution pro...
