Problems solved by technology

This type of method is suitable for scenarios with high similarity of parallel programs, but the estimation method is difficult to design and implement and it is difficult to guarantee the accuracy
The dynamic detection scheduling method uses a heuristic algorithm for detection and task migration scheduling in the process of task execution, which helps to allocate tasks to each processor reasonably, but this type of algorithm is more complicated, and the detection process increases task scheduling. overhead, which increases system overhead and offsets its balanced scheduling benefits

Abstract

The invention relates to the field of metadata modeling and analysis technology, in particular to a data service pre-playing preview task scheduling method. According to the method, first, a test taskscheduling model is established, the load level of processors is calculated through working loads and communication loads of the processors to serve as a measurement standard during scheduling, an active report mode is adopted to design a task scheduling algorithm, a test task is decomposed into multiple subtasks, and the subtasks are distributed to the processors to complete running. Through themethod, idle processor resources are utilized to realize scheduling, distribution and automatic completion of the test task, collection and recovery of a test result and the like, the test task is reasonably scheduled, overhead is reduced, problems existing in traditional methods are effectively solved, and test speed is increased.

Description

Technical field [0001] The invention relates to the technical field of metadata modeling and analysis, and more specifically, to a method for scheduling preview tasks before broadcasting of data services. Background technique [0002] With the introduction of new network technologies, the introduction of new business requirements, and the construction of a new operation and maintenance management system, the status of metadata has been highlighted to cope with the continuous fragmentation and increase of operation and maintenance data. Valuable data cannot be capitalized, and the operation and maintenance support system Problems such as low revenue and information overload. However, there are data identification conflicts and inconsistent data items among various systems, and it is difficult to support effective management and analysis of subsequent data. To this end, combined with the metadata structure of different systems such as the operation and control of the power communi...
