Description

METHOD AND SYSTEM FOR PROCESSING SIMULATION DATA BACKGROUND OF THE INVENTION [0001]

The present invention relates to a method and an apparatus for processing simulation work information, and more particularly, to a method and apparatus for processing simulation work information by inserting a push code (push code) And more particularly, to a method and system for processing simulation data that can be applied to task managers having operational characteristics collectively and to reduce the load on a server.

The multi-tier architecture is a system that adds a middle tier to a client / server model in a distributed network. As the existing client / server model evolves into a 3-tier model consisting of client, database server, and intermediate application processing server, the client interacts with the database server through the middle tier, It is responsible for data processing of the database. This structure is extended to N-tier systems when various tasks are added to the client. It also has benefits such as program creation and data distribution, independent use of the processor or operating system (OS) platform, and independent update performance.

Simulation, on the other hand, is to predict the actual situation by performing an experiment that simulates a phenomenon or the operation of equipment by a computer. These simulations have great advantages in terms of time and cost and are widely used in research fields and industries that deal with computational chemistry, computational fluid dynamics (CFD), structural mechanics, etc. .

Referring to FIG. 1, when a user inputs simulation job information through a client terminal, the job information is transmitted to a job management server after a job script is converted by a web application server, and a simulation is executed. The user is allowed to confirm the simulation result corresponding to the simulation work information inputted by the user.

However, each task manager (e.g., PBS, LoadLeveler, SGE, etc.), which is a program used by the task management server to manage the simulation task information, has unique characteristics. For example, there may be a difference between job submission method, job log (log), or job status recording method of job managers, and there is no technology for collecting smooth simulation results by applying these job managers collectively to be.

Specifically, each of the task managers deletes the effective time (e.g., 30 minutes, 1 hour, etc.) holding the history of the data processed by the task managers, and after the effective time elapses, The application server has a great technical difficulty in recognizing and updating the status information on the progress of the simulation work from the job management server.

According to the related art, the web application server and the job management server communicate with each other at regular intervals using a polling method. Such a polling method is a method in which a server is overloaded (E.g., overhead), and the longer the period, the lower the real-time response characteristic.

Accordingly, there is a demand for a technology that allows the user to accurately recognize and update the result of the simulation request requested by the user, while reducing the load on the server while simultaneously receiving information on the progress of the simulation operation without loss Is increasing.

In step S1300, the web application server (WAS) 200 may store the simulation work progress information in the work information DB 240 in a time series before the work progress information notification step (S1400).

Accordingly, only when the work progress information notification request is transmitted from the client terminal 100 (S1310), the web application server (WAS, 200) (S1320) and transmits the simulation work progress information to the client terminal 100 side.

Such simulation progress information may include waiting for a job, starting a job, job success, job failure, cause of a job failure, data of a simulation result completed (or working), information about the time required for the job and the progress of the job. In addition, the simulation work progress information may be a predetermined item through the design of the push code. For example, the push code may be designed to push only specific information out of the information included in the above-described simulation work progress information.
