Embodiment Construction

[0042] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0043] The invention provides a method of job scheduling based on seismic data, such as figure 1 shown, including the following steps:

[0044] S1. Obtain resource information of cluster nodes.

[0045] Such as figure 2 As shown, this step includes the following sub-steps:

[0046] S11. A computing cluster node.

[0047] S12. Read configuration files, including / proc / stat system files, / proc / net / dev system files, and / etc / mtab system files.

[0048] Among them, the / proc / stat system file contains many statistical information about the kernel and the system since the system was started, including CPU operation, interrupt statistics, startup time, number of context switches, running processes and other information.

[0049] The / proc / net / dev system file contains system network card statistics.

[0050] The / etc / mtab system file records the file syst...

Abstract

The invention discloses an operation scheduling method based on seismic data, comprising the following steps: S1, acquiring resource information of cluster nodes; S2, calculating the complexity of seismic operation; and S3, scheduling seismic operation through an operation scheduling strategy based on a chaos algorithm. The method of the invention is based on a seismic operation scheduling strategy under the conditions of optimal total processing time and load balancing. Seismic operation scheduling is finally implemented through the seismic operation scheduling strategy based on the chaos algorithm according to the acquired resource information of the cluster nodes and the complexity of seismic operation.

Description

technical field [0001] The invention belongs to the field of cluster technology, and in particular relates to the design of a seismic data-based job scheduling method. Background technique [0002] With the continuous development of technology, although the performance of a single computer is getting higher and higher, but in the processing of large-scale data such as seismic data, only relying on the continuous enhancement of the ability of a single computer can no longer meet the growing needs of applications. Generally, large-scale seismic data can be as high as hundreds of GB, and its calculation is very complicated. The running time of a seismic data processing can reach up to ten days, so the cluster technology provides us with a solution. [0003] Cluster technology is a relatively new technology. Through cluster technology, relatively high benefits in terms of performance, reliability, and flexibility can be obtained at a lower cost. Among them, task scheduling is a ...
