Embodiment Construction

[0051] The gist of the present invention is to overcome the deficiencies of the prior art, to provide a mathematical formalization method for describing the dependency relationship of the distributed workflow in the inversion process of MOSDIS data land atmospheric aerosol remote sensing, and to describe the dependency relationship, parallelism and serial relationship. Through this mathematical formalization method, related scheduling algorithms can be written to drive the orderly execution of the aerosol inversion process in a distributed computing environment. The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.

[0052] Method flow chart of the present invention is as figure 1 As shown, the present invention establishes a software architecture method on the basis of mathematical formalization, which is a strict and effec...

Abstract

The invention provides a method for depicting terrestrial atmospheric aerosol retrieval distributed workflow dependency, and relates to the field of high-performance geocomputation, in particular to cloud computing-oriented MOSDIS (Moderate-Resolution Imaging Spectroradiometer) data. According to the method, through establishment of a multiple element group, six key elements are used to describe a finite graph distributed in a network in a mathematical formalization manner to realize mathematical formalization depiction of the aerosol remote sensing retrieval distributed workflow dependency; and after related remote sensing processing tasks, configuration and control information are acquired through interpretation of the abstract depicting method, an abstract service flow is subjected to resource mapping to obtain Web Service-encapsulated remote sensing retrieval processing and data processing related service to drive an aerosol retrieval processing process to be executed in the distributed calculation condition. In a flow definition phase, the Web Services are called; and through conversion control of four construction modules of AND-split, AND-join, OR-split and OR-join, ordered execution can be realized according to the relations between parallel and serial, and predecessor and successor, so that the quick retrieval of aerosol is realized.
