Description
Technical field
The present invention relates to scientific algorithm field, and especially, it is related to the implementation method and dress of a kind of calculating task of CFX
Put.
Background technology
CFX is first, the whole world in complex geometry, grid, solves and obtain great in these three CFD tradition bottle diameter problems
The commercial CFD software of breakthrough, by means of its unique technical characterstic, leads high-performance CFD business software of new generation
Overall development trend, 2003, CFX was added in the extended family of the CAE simulation softwares ANSYS of global maximum.
In traditional HPCC environment, user will run the calculation procedure based on CFX softwares generally two
The mode of kind：One is, in the use environment of job scheduling, to need one is performed under command line environment using remote character terminal and be
Row operation, typically has following flow process：
The executable file of CFX calculation procedures, input file, data file etc. are got out, these files generally need to put
Put in the globally shared storage of cluster, user generally uses the instruments such as FTP, SFTP and uploads these files to cluster, most
In the case of number, user also needs to carry out edit-modify to input file etc. with the text edit tool.
It is determined that running the number of passes that enters of CFX calculation procedures needs, and run on which node, these information are passed through
The mode of command line parameter passes to the process initiation device of CFX, and by the process initiation device startup optimization of CFX, the CFX calculates journey
Sequence.
After the completion of program operation, result of calculation is checked, or destination file is downloaded to user's sheet using instruments such as FTP, SFTP
Ground terminal.
It is more than the main flow for directly running CFX calculation procedures, under practical situation, user is on HPCC
Submit parallel computation task to, the interface for needing unification to provide using job scheduling software, user generally also need to write one again
Job scheduling script, applies for computing resource in script, submits parallel computation task to by this script, by job scheduling software
Come process task queuing, Resources allocation, initiate concurrent program.
Another way is the graphical operation interface using CFX calculation procedures, typically has following flow process：

Some professional tools, need to perform complicated loaded down with trivial details operation in command line environment, so as to cause the submission expense of parallel computation task
When it is laborious, execution efficiency is low.
Error probability is big.For most of domestic consumer, complicated loaded down with trivial details operation is performed in command line environment, occurred
The probability of human operational error is very big.It is especially for the unfamiliar user of operating process, easy in the links for performing
Encounter problems.
For the manager of HPCC, to domestic consumer's open command row terminal, safety is there is also
Risk, the maloperation of user may affect the stable operation of system, hacker to be also possible to avail oneself of the opportunity to get in.
Using the method for the graphical operation interface of CFX calculation procedures, it is impossible to make application program with job scheduling organically
Combine so that job scheduling software cannot come process task queuing, Resources allocation, initiate CFX concurrent programs, using figure
During shape operation interface, fixed calculate node in HPCC can only be provided the user by hand and complete to calculate, i.e., without
Size dynamic regulation computing resource of the method according to amount of calculation, also simultaneously cause calculate node it is idle again when cannot reuse
Computing resource waste.
In the prior art, although there are some business software for calculation and provide the parallel computation task of oneself by graphical
Submit to interface to carry out instruction submission, but be both for individual software, no universality, and it is further desired that special client is soft
Part cooperation is completed, and the combination of job scheduling software cannot be realized or be there is a problem of different degrees of.
