Embodiment Construction

[0040] The generation method and device of the present invention will be explained and illustrated in detail below in conjunction with the accompanying drawings.

[0041] Such as figure 1 , 2 , 3, the present invention discloses a method for generating a task scheduling scheme in a scientific workflow in a cloud environment. The present invention innovatively combines list scheduling, task duplication, and task insertion, and can be applied to a network with an unlimited number of processors. Execute task scheduling strategies in a homogeneous environment. For the convenience of subsequent description, the present invention is defined as follows.

[0042] The execution plan generation of the scientific workflow is to map the workflow tasks reasonably to the computing resources, and the computing resources involved in the present invention are processors; F represents the mapping, T={t i , t i is the task in the workflow, i=1,2,3,...,n, n is the number of tasks}; V={v j , ...

Abstract

The invention discloses a method and device for generating a task scheduling plan in a scientific workflow in a cloud environment. The method includes the following steps: step 1, obtaining all tasks to be scheduled; step 2, using weighted directed The ring graph describes the tasks to be scheduled; step 3, in the directed acyclic graph, traverse from the start node to the end node to obtain all paths; step 4, calculate the time consumption of each path, according to the time consumption by Sorting all paths in descending order and determining the priority of the paths in descending order; step 5, generating a task scheduling scheme according to the priority order of the paths; the device includes a task acquisition module, a task description module, a node traversal module, a path sorting module and Program generation module. The invention can make full use of the idle time of the processor, improve the parallelism of scientific workflow task execution, improve the utilization rate of the processor, and shorten the completion time of the scientific workflow task.

Description

technical field [0001] The invention relates to the technical field of scientific workflow task scheduling, and more specifically, the invention is a method and device for generating a task scheduling scheme in a scientific workflow in a cloud environment. Background technique [0002] Scientific Workflow (SWF) is a new application generic developed in recent years, which supports scientific researchers to integrate, construct and collaboratively distribute heterogeneous data, services and software tools, and provides a complex scientific computing process and an automated management platform. Compared with the traditional control-flow-oriented business flow (Business Workflow, BWF), data-flow-oriented is one of the important characteristics of scientific workflow. [0003] With the development of science and technology, SWF has gradually developed into a data- and computing-intensive application generic, and its data generation speed and scientific computing have become in...
