Description
Technical field
The present invention relates to field of computer technology, more specifically, relate to a kind of Web service method for packing for marine numerical simulation computing system ROMS and Web service package system.
Background technology
Numerical simulation is the important means of ocean research, is bringing into play more and more important effect in scientific research of seas.And the partial differential equations of ocean numerical model by numerical solution control seawater movement realizes the numerical simulation to seawater movement.In the numerical model of numerous oceans, ROMS (Regional Ocean Modeling System) is one of them zone and ocean circulation pattern, and as one of main ocean businessization pattern, ROMS is used in a large number.ROMS adopts Fortran90/95 to write, and supports to share and distributed two kinds of computer body system structures, has that computation-intensive, IO read-write amount are large, the network bandwidth requirement high.The ROMS pattern has preferably parallel-expansion, and problem scale hour can accelerate to 100 nuclears nearly, can reach 200-600 nuclear when problem scale is larger.Simultaneously, ROMS also can form coupled mode with other maritime meteorology pattern, the drive pattern of perhaps using as other maritime meteorology.
The calculated amount of carrying out marine numerical simulation with ROMS is generally larger, therefore need to carry out parallel computation at HPCC.In the mode of operation that has now, the user need to use long-range character terminal to be connected to HPCC usually, and carries out sequence of operations and just can finish this numerical simulation under command line environment, generally comprises following several flow process:
The calculated amount of carrying out marine numerical simulation with ROMS is generally larger, therefore need to carry out parallel computation at HPCC.In the mode of operation that has now, the user need to use long-range character terminal to be connected to the HPCC system usually, and carries out sequence of operations and just can finish this numerical simulation under command line environment, generally comprises following several flow process:
Prepare the executable file of ROMS and the data file that needs thereof.These files usually need to be placed on the overall situation of cluster and share in the storage, and the instruments such as user's normal operation FTP, SFTP are uploaded these files to cluster, and in most of the cases, the user also needs with the text edit tool these files to be made amendment.
If on the calculating group system job scheduler is arranged, then the user need to use text editor to write a script file, wherein fills in the computational resource quantity that needs application, and the order of operation ROMS program, then uses job scheduling order submit job.If there is not job scheduler, then the user need to be with the process number of operation ROMS program and the process initiation device that passes to MPI in the mode that the information exchanges such as which node operation are crossed command line parameter, such as mpirun, mpiexec etc.Process initiation device booting ROM S program by MPI is carried out parallel computation.
After the program operation is finished, use the instruments such as FTP, SFTP to download destination file and check result of calculation to the subscriber's local computing machine.
There is following defective in the method for existing operation ROMS calculation procedure:
(1) use difficulty large.Want to finish smoothly the calculation task of ROMS program, the user often needs to be familiar with very much computer literacy and the instruments of a lot of meter specialties, such as (SuSE) Linux OS basic operation, Shell script, text editing commonly used and character handling implement, the use of MPI environment, use of job scheduling software etc.
(2) execution efficient is low.Want to submit to smoothly the calculation task of a ROMS program, need to carry out a plurality of flow processs, need to carry out complicated loaded down with trivial details operation in command line environment, thereby cause the submission of parallel computation task to waste time and energy inefficiency.
(3) error probability is large.For most of domestic consumer, carry out complicated loaded down with trivial details operation in command line environment, the probability that the human operational error occurs is very large.Particularly for the unfamiliar user of operating process, all easily encounter problems at the links of carrying out.
(4) security risk is high.Need to the capable terminal access authority of domestic consumer's open command, for the keeper of HPCC, there be the risk of security in traditional method of operating to the capable terminal of domestic consumer's open command.User's maloperation may affect the Systems balanth operation, and the hacker also might avail oneself of the opportunity to get in.
