Embodiment 1
[0050] like figure 1 As shown, it is a flow chart of a general multi-computer parallel computing method in this embodiment, including the following steps:
[0051] Step 101, obtaining computing tasks;
[0052] Step 102, acquiring the capability parameter of each computing node of the computing resource, and calculating the processing capability of each computing node according to the capability parameter;
[0053] Parallel computing for geophysical acquisition usually has the characteristics of large amount of calculation, small input data, and huge result data, and there are certain differences in different types of applications. Therefore, an application type factor f is defined a , used to characterize the input data size d in a certain type of application i , calculation amount c a , result data d o The relationship between size is an important reference item in the process of parallel task scheduling. The initial application type factor is calculated as follows:

Abstract
The invention provides a general multiprocessor parallel calculation method and system. The method comprises the steps that a calculation task is obtained, hardware information and software information of all calculation nodes of a calculation resource are obtained, and the processing capacity of each the calculation node is calculated according to the hardware information and software information; according to the internal parallelizability of the calculation task, the calculation task is decomposed into multiple sub calculation tasks; according to the processing capacity of each calculation node, the sub calculation tasks are matched with all the nodes; according to a basic communication protocol, the data format of the sub calculation tasks is converted to a protocol format, and according to the matching relation, the sub calculation tasks are distributed to all the calculation nodes; according to the basic communication protocol, calculation results, of the protocol format, fed back by the calculation nodes are obtained, the data format of the calculation results is converted to the format of the original calculation task from the protocol format, and then the calculation results are fed back. Multiprocessor parallel calculation under the heterogeneous environment is achieved.
Description
technical field [0001] The invention relates to the technical field of communication in a heterogeneous environment, in particular to a general multi-machine parallel computing method and system. Background technique [0002] With the progress and development of geophysical technology and equipment, seismic acquisition software at home and abroad is also facing changes in the demand for large-scale data processing and high-efficiency high-performance computing, such as 3D lighting, tomographic static correction, and forward modeling of wave equations. It takes a long time, and the traditional stand-alone processing mode is far from meeting the needs of high-performance computing. It is the general trend to support large-scale data processing, high-performance, and efficient computing. At present, the seismic acquisition system is faced with a complex, heterogeneous computing environment with huge performance differences, rather than the expensive homogeneous cluster system r...
