Description
Technical field
The present invention relates to field of computer technology, calculates for mesoscale Numerical weather forecasting more particularly, to a kind of
The Web service method for packing and Web service package system of system MM5.
Background technology
Meso-scale meteorology is the important branch quickly grown in modern weather science, the air mesoscale studied by it
Motion, is related to the discovery and prevention of the important diastrous weather in region.One side therein be by meso-scale model, it is right
Study of Meso Scale Weather process carries out deep simulation study and forecast experiments.With developing rapidly for computer technology in recent years, in
Yardstick numerical model is reached its maturity.Mesoscale Numerical weather forecasting pattern has many, such as MM5 computing systems (Mesoscale
5) Model is the relatively broad pattern of current domestic and international application.
The amount of calculation that marine numerical simulation is carried out with MM5 is generally large, it is therefore desirable to carry out on HPCC
Parallel computation.Now with mode of operation in, user generally needs to be connected to high-performance calculation collection using remote character terminal
Group's system, and under command line environment, execution sequence of operations can just complete this numerical simulation, generally comprise following several
Individual flow process：
Prepare the data file of the executable file and its needs of MM5.These files generally need to be placed on the complete of cluster
In the shared storage of office, user generally uses the instruments such as FTP, SFTP and uploads these files, in most of the cases, user to cluster
Also need to modify these files with the text edit tool.
If there is job scheduler in computing cluster system, user needs to write a script text using text editor
Part, wherein fill in that the computing resource quantity of application is needed, and the order of operation MM5 programs, then using job scheduling order
Submit operation to.If no job scheduler, user need by operation MM5 programs enter number of passes and on which node transport
The information such as row pass to the process initiation device of MPI, such as mpirun, mpiexec etc. by way of command line parameter.By MPI
Process initiation device start MM5 programs carrying out parallel computation.
After the completion of program operation, destination file is downloaded using instruments such as FTP, SFTP and check calculating to user's local computer
As a result.
There is following defect in the method for existing operation MM5 calculation procedures：
(1) it is big using difficulty.Want to smoothly complete the calculating task of MM5 programs, user generally requires very familiar a lot
The computer literacy and instrument of meter specialty, such as (SuSE) Linux OS basic operation, Shell scripts, conventional text editing
Use etc. with character handling implement, the use of MPI environment, job scheduling software.
(2) execution efficiency is low.Want smoothly to submit the calculating task of a MM5 program to, need to perform multiple flow processs, need
Complicated loaded down with trivial details operation, so as to the submission for causing parallel computation task is wasted time and energy, inefficiency are performed in command line environment.
(3) error probability is big.For most of domestic consumer, complicated loaded down with trivial details operation is performed in command line environment,
The probability for human operational error occur is very big.It is especially for the unfamiliar user of operating process, equal in the links for performing
It is likely to encounter problem.
(4) security risk is high.Traditional operational approach is needed to domestic consumer's open command row terminal access authority, for
For the manager of HPCC, there is the risk of safety to domestic consumer's open command row terminal.The mistake of user
Operation may affect the stable operation of system, hacker to be also possible to avail oneself of the opportunity to get in.
For the problem in correlation technique, effective solution is not yet proposed at present.
