Multitask execution method in large software

Abstract

The embodiment of the invention discloses a multi-task execution method in a large software, which comprises the following steps: generating operation instructions of various services, ordering the operation instructions to generate an execution list of the operation instructions according to the time sequence and the dependence relationship generated by the operation instructions, sending the operation instructions to relative functional modules according to the execution list of the operation instructions, and executing corresponding tasks of the operation instructions. Through using the method, a whole system is separated into different function modules according to task types, the tasks are executed by the function modules which correspond to the task types, thereby simplifying the maintenance work of the software, and increasing the execution efficiency of asynchronous instructions.

Description

technical field [0001] The invention relates to the field of software development, in particular to a multitask execution method in large-scale software. Background technique [0002] With the development of IT technology and the rapid development of storage devices and processor cores, the scale of software that the system can support is also expanding. The current large-scale software contains a lot of functions. In the past, the sending of various instructions in the system and execution are all done in one module. Although this can be centrally managed and functional, it has many disadvantages: [0003] 1. The software will become very large, complex, and unstable; [0004] 2. It is not conducive to the modification of the software. When a certain function is modified, the entire software needs to be recompiled and republished; [0005] 3. The upgrade of other software has an impact on itself. When the completion of some functions requires interaction with other softw...

AI Technical Summary

Problems solved by technology

[0003] 1. The software will become very large, complex and unstable;

[0004] 2. It is not conducive to software modification. When a certain function is modified, the entire software needs to be recompiled and republished;

[0005] 3. The upgrade of other software has an impact on itself. When the completion of some functions needs to interact with other software, with the upgrade of these software and the change of the interaction protocol, the software must also be upgraded, although it may be very small A function, but results in a modification of the entire software

[0006] 4. The processing of asynchronous commands is not good enough. When some commands take a long time to execute, the software cannot wait online, and other technologies need to be used, such as creating new threads to complete;
