Problems solved by technology

But the FORTRAN program has its obvious shortcomings: the user interface is not friendly, and the visualization is poor
[0004] This strategy keeps the level of encapsulation at the language level, which has been improved in terms of visibility and ease of use. However, the FORTRAN legacy programs that are split and encapsulated according to this strategy can only be deployed on one machine. It can't reach the level of distributed and cross-platform, so the reusability of FORTRAN code is not high in essence
[0005] From the above analysis, we can see that for FORTRAN legacy programs, the existing method is to deploy them on the same machine, so the communication between modules can be realized through shared memory variables, but in a distributed environment, this communication mechanism is not working

Embodiment Construction

[0084] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0085] The weather simulator is written in FORTRAN language. In order to encapsulate it as a Web Service, we use the file method to transfer a large amount of global variable data. The specific steps are as follows:

[0086] 8.1 Encapsulate the weather simulator module into a Web Service, the specific steps are as follows:

[0087] 1) Write an adapter for the original meteorological simulator module in FORTRAN language, which is responsible for parsing the incoming global variable file and generating the output global variable file. The formats of the input and output files are defined in advance. The input global variable file includes two parts: the read geographical data file name and the corresponding file pointer, and the data of the global variable.

[0088] 2) Write an encapsulation program in C language, responsible for commun...

Abstract

The invention discloses a communication method among distribution type FORTRAN modules, belonging to the technical field of software. The method comprises the following steps of: 1) sequentially packing FORTRAN modules distributed on each host computer by means of C language and Java language to generate a Web Service module which comprises an adapter; 2) generating a global variable document A which is transmitted to a host computer B through a host computer A, and communicating the host computer A with the host computer B through the Web Service module; 3) analyzing the document A through the adapter of the host computer B, and assigning value to a parameter; 4) executing operation to the adapter of the host computer B through the FORTRAN modules, and generating a global variable document B through the adapter; 5) transmitting the generated document B to the host computer A through the adapter of the host computer B; and 6) analyzing the document B through the adapter of the host computer A, assigning value to a parameter, and transmitting the parameter to the FORTRAN modules. The communication method greatly improves the reusability of a FORTRAN legacy program.

Description

technical field [0001] The invention relates to a communication method among distributed FORTRAN modules, belonging to the technical field of computer software. Background technique [0002] The FORTRAN language was born in the 1950s. Due to its simple grammatical structure, powerful scientific computing functions, especially its unique advantages in complex number operations, it is widely used in the fields of mathematics and engineering computing. Many early engineering application calculation programs and software were written in FORTRAN language. But the FORTRAN program has its obvious disadvantages: the user interface is not friendly and the visualization is poor. [0003] How to continue to use a large amount of FORTRAN legacy code and reduce waste; at the same time, how to make the application program have a friendly man-machine interface like C++, VB, Delphi? The general strategy is to use mixed language programming and encapsulate FORTRAN codes with C / C++, VB, and...
