Method and system for cross-thread communication based on message queue

Abstract

The invention provides a method and a system for cross-thread communication based on a message queue. The method comprises the following steps: adopting the message queue to execute operations of multi-thread enqueuing push and single-thread dequeuing pop, wherein the operation of the multi-thread enqueuing push comprises the following steps: judging whether the message queue is full, and if not, respectively calculating the offset of enqueuing push of n threads, wherein the n is an positive integer more than or equal to 1; according to the offset of the enqueuing push of the n threads, respectively calculating actual positions Pos of the enqueuing push of the n threads, wherein the n threads execute enqueuing push operation respectively at the actual positions Pos of the enqueuing push. The method and system provided by the invention have the advantages that no collision of access operation of the n threads is guaranteed, the problem of blocking in cross-thread communication is solved, the resource consumption is reduced, the resources of the system are fully utilized, and the processing speed is improved, so that the throughput of a server is increased.

Description

technical field [0001] The invention relates to the technical field of computer communication, in particular to a method and system for inter-thread communication based on message queues. Background technique [0002] Throughput refers to the sum of the amount of data transmitted on the network during a performance test. For interactive applications, the throughput index reflects the pressure on the server. In the test of capacity planning, the throughput index shows the load capacity at the system level. With the continuous growth of user traffic and the continuous accumulation of enterprise data, the throughput requirements for servers are also getting higher and higher. [0003] In order to improve the throughput, the server can adopt multi-threading technology, which mainly solves the problem of executing multiple threads in the processor unit, reduces the idle time of the processor unit, and increases the throughput capacity of the processor unit. When solving the pro...

Problems solved by technology

Therefore, the method of using mutex instructions consumes a lot of resources, and the push and pop instructions in the queue cannot be performed at the same time. One thread is always blocked by another thread and cannot make full use of system resources.
