Description
Technical field
The science that the present invention relates to is calculated field, and especially, relates to implementation method and the device of the calculation task of a kind of ABAQUS.
Background technology
ABAQUS is the finite element software of a set of powerful engineering simulation, the nonlinear problem of its scope of dealing with problems from relatively simple linear analysis to many complexity, ABAQUS comprise one abundant, can simulate the cell library of random geometry, and have various types of material models storehouse, can simulate the performance of typical project material, comprising metal, rubber, macromolecular material, compound substance, reinforced concrete, the geological materials such as compressible super-elasticity foamed material and Soil and Rock, as general simulation tool, ABAQUS is except solving a large amount of structures (stress/displacement) problem, can also simulate many problems in Other Engineering field, for example heat conduction, mass diffusion, crack preventing, acoustic analysis, rock-soil mechanics is analyzed (analysis of fluid permeability/stress coupling) and piezoelectric dielectric analysis.
In traditional HPCC environment, the calculation procedure that user will move based on ABAQUS software has two kinds of modes conventionally: the one, in the environment for use of job scheduling, need to use long-range character terminal to carry out sequence of operations under command line environment, generally have following flow process:
Be ready to executable file, input file, data file of ABAQUS calculation procedure etc., these files conventionally need to be placed on the overall situation of cluster and share in storage, user generally uses the instruments such as FTP, SFTP to upload these files to cluster, in most of the cases, user also needs, with the text edit tool, input file etc. is carried out to edit-modify.
Determine the process number that this ABAQUS calculation procedure of operation needs, which and move on node, the mode that these information exchanges are crossed to command line parameter passes to the process initiation device of ABAQUS, and the process initiation device by ABAQUS starts this ABAQUS calculation procedure of operation.
After program has been moved, check result of calculation, or use the instruments such as FTP, SFTP to download destination file to subscriber's local terminal.
It is more than the main flow process of directly moving ABAQUS calculation procedure; under actual conditions; user submits parallel computation task on HPCC; the unified interface that uses job scheduling software to provide is provided; user also needs to write a job scheduling script conventionally again; in script, apply for computational resource, by this script, submit parallel computation task to, by job scheduling software, come Processing tasks queuing, Resources allocation, initiation concurrent program.
Another kind of mode is the graphical operation interface of using ABAQUS calculation procedure, generally has following flow process:
User generally uses the instruments such as FTP, SFTP to cluster, to upload the data file of ABAQUS calculation procedure.
Start the graphical operation interface of ABAQUS calculation procedure, select to calculate needed data file, the required calculating parameter of computational data file and the process number needing, nodes etc. are set, mouse is clicked computing button and is started computing.
After program has been moved, check result of calculation, or use the instruments such as FTP, SFTP to download destination file to subscriber's local terminal.
Be more than the main flow process that starts graphical operation interface operation ABAQUS calculation procedure, job scheduling software cannot carry out calculation task to it and process the operations such as queuing, Resources allocation.
Introduced above in traditional HPCC environment, the two kind basic operation procedures of user's operation based on ABAQUS calculation procedure, the first flow process conventionally need to be under long-range character terminal, mode by order line realizes, vast domestic consumer for non-bone ash level, operation easier is large, and execution efficiency is low, and error probability is large; Although the second flow process decreases in operation easier, in man-machine interaction, experience better, but cannot use the queuing of HPCC job scheduling software Processing tasks, Resources allocation, initiation concurrent program, be that whole high-performance calculation resource cannot in order, efficiently and reasonably be used, even cause the waste of computational resource and distribution uneven.
The drawback of above two kinds of executive modes is mainly manifested in:
Use difficulty very large.Want to submit to smoothly an ABAQUS parallel computation task, user often needs to be familiar with very much a lot of knowledge and instrument a lot of and that its specialty background is irrelevant, such as use of the calling of (SuSE) Linux OS basic operation, Shell script, conventional text editing and character handling implement, MPI environment, job scheduling software etc., the learning curve of these knowledge or instrument is very steep, skilled grasp usually needs to spend the time of several years, and such trace utilization cost is very huge concerning vast domestic consumer.
Execution efficiency is low.Want to submit an ABAQUS parallel computation task to smoothly, need to carry out a plurality of flow processs, need to use some professional tools, need to carry out complicated loaded down with trivial details operation in command line environment, thereby cause the submission of parallel computation task to be wasted time and energy, execution efficiency is low.
Error probability is large.For most of domestic consumer, in command line environment, carry out complicated loaded down with trivial details operation, occur that human operational error's probability is very large, particularly for the unfamiliar user of operating process, at the links of carrying out, all easily encounter problems.
, also there is the risk of security in the capable terminal of ，Dui domestic consumer open command for the keeper of HPCC, user's maloperation may affect the stable operation of system, and hacker also likely avails oneself of the opportunity to get in.
Use the method at the graphical operation interface of ABAQUS calculation procedure, can not make application program and job scheduling organically combine, make job scheduling software cannot come Processing tasks queuing, Resources allocation, initiation ABAQUS concurrent program, when using graphical operation interface, can only for providing computing node fixing in HPCC, user complete calculating by hand, cannot be according to the big or small dynamic adjustments computational resource of calculated amount, the computing resource waste that cannot reuse while also simultaneously having caused computing node idle again.
In the prior art, although exist some business software for calculation to provide the parallel computation task of oneself to carry out instruction submission by graphical submission interface, but be all for indivedual software, there is no universality, and, also need special client software to coordinate, cannot realize or exist problem in various degree with the combination of job scheduling software.
While moving ABAQUS calculation procedure for user in correlation technique, need under long-range character terminal, the mode by order line realize, operation easier is large, and execution efficiency is low, and the problem that error probability is large not yet proposes effective solution at present.
