Description

A kind of numerical forecast operation system framework and method for designing
Technical field
The present invention relates to computer realm, specifically, relate to a kind of numerical forecast operation system framework andMethod for designing.
Background technology
Numerical forecast comprises meteorological numerical forecast, Marine Numerical Prediction and atmospheric environment numerical forecast etc., isRefer to, under certain initial value and boundary value condition, make numerical computations by mainframe computer, solve and describe large QihaiHydrodynamics and the thermodynamic (al) equation group in ocean, the Atmosphere and Ocean motion state of certain period of predict future is gentleResemble the method for oceanographic phenomena. At present, numerical forecast is widely used, and becomes each operational forecast unitRequisite forecast means.
A complete numerical forecast flow process generally comprises data preparation, data pre-processing, mode computation, knotSeveral parts such as fruit post processing and forecast result issue. Because flow process is various, and need carry out every day, because ofThis needs computer automatic technology to realize businessization operation (start by set date, operation automatically), with regard to shapeBecome numerical forecast business system.
The unit that carries out numerical forecast business is country, province City Weather Bureau, country, marine forecasting center, regionAnd national, provincial, and municipal level environmental administration. At present, Numerical Prediction System majority by constituent parts business personnel voluntarilyExploitation. The exploitation of current value operational forecast system and running are:
The debugging of Numerical Prediction Models: delimit according to demand survey region, prepare related data, operation numerical valueForecast Mode, and adjust numerical model parameter scheme according to analog result, to reach good analog result.
Bibliographic structure planning: the bibliographic structure of design value forecast business system, design value prediction program,Storing directory and the dependency structure of implementing procedure, script, forecast data etc.
Each module script exploitation: with shell language or other script compile scripts, write modulesThe Run Script program of (data pre-processing, mode computation, result post processing, forecast result are issued), andEach module is carried out to independent debugging.
Numerical forecast business system integration debugging: the script of modules is together in series, and on the wholeCarry out the combined debugging of modules, find out operating problem and revised.
The trial run of numerical forecast operation system: operation system is deployed as to automatic operation, carries out trial run period,Whether the operation of observed traffic system is stable, and the problem occurring is corrected, and strengthens stability.
The O&M of numerical forecast operation system: operation system enters the commencement of commercial operation stage, monitors that numerical value is pre-during this timeThe operation conditions of report operation system, processes the fault occurring, and ensures the timely generation of numerical forecast result.
At present, Numerical Prediction System majority is by constituent parts business personnel self-developing, the numerical forecast industry of various placesThe ununified standard of business script, and owing to lacking professional Experiences in Developing Software, the business pin of its exploitationThis is generally not enough aspect fault-tolerance, viability, and there are the following problems:
Structure is unintelligible, and intermodule degree of coupling is large, is difficult to transformation and expansion;
The linking of each module is unreliable, causes sporadic mistake;
Without flow monitoring, cannot check detailed operation progress and the situation of operation;
Enough diagnostic messages are not provided while makeing mistakes, and misarrangement is wasted time and energy;
Pre-process and post-process module is not carried out parallelization, and performance is lower, consuming time longer;
In script, use absolute path, migration difficulty, the migration cycle is long;
The setting position that parameter is ununified, there are many places in same parameter, parameter modification difficulty, and easily loseLeak.
Cause the reason of this problem to have two aspects: on the one hand, numerical forecast operation system amount of calculation is huge,Need on high-performance computer, move; High-performance computer is taking aggregated structure as main at present, and multiple calculating savesPoint is interconnected by network system, has worked in coordination with calculation task; This aggregated structure brings the same of high calculated performanceTime, also because the laxity of structure is brought reduction and the managerial complexity of reliability, computing subsystem,Any Single Point of Faliure of storage subsystem, network subsystem etc., all may cause fault or the interruption of business;For the business personnel who is unfamiliar with high-performance computing environment, the difficulty of investigation traffic failure is larger; Numerical valueThe many script exploitations based under Linux environment of operational forecast system, the workloads such as script debugging, malfunction eliminationAll larger with difficulty. On the other hand, the operation of the each component part of numerical forecast operation system has serial program,Also there is concurrent program, between operation, have comparatively complicated dependence, form comparatively complicated logical construction;The complexity of flow process has increased the difficulty of management, how effectively whole operation flow to be carried out to monitoring management, isA problem that need solve.
