Abstract

Embodiments of the present application provide a process communication method and apparatus in a cluster system. The method includes: determining a startup relationship between process numbers, wherein the startup relationship includes a cell division type startup relationship; starting a process in a cell division manner according to the startup relationship between the process numbers; causing each process to send address information thereof to the 0 process during the process startup; performing inter-process communication; when first communication is made between the processes, the two communicating parties inquire about the address information of the other party from the 0 process. The method and the device can improve the parallel processing efficiency of a cluster system and have the advantages of high performance, high scalability and ease of use; the method and teh device can meet the needs of the development of a massive data parallel computing framework in computation-intensive and data-intensive exploration geophysics, and significantly improve the development efficiency and quality of large-scale parallel and distributed seismic applications.

Description

technical field [0001] The present application relates to the technical field of computer communication, in particular to a process communication method and device in a cluster system. Background technique [0002] In recent years, with the development of seismic acquisition technology, the data volume of seismic data has been increasing continuously. At the same time, some advanced algorithms with a large amount of calculation have gradually entered into production and practical use. The parallel calculation of massive seismic data has further strengthened the demand for ultra-large-scale parallel computing systems. . Due to the lack of matching parallel implementation technology framework, the ultra-large parallel scale and polymorphic and complex architecture of the cluster system have brought great challenges to traditional high-performance computing applications. Most of the current parallel implementations for cluster computing systems are based on a two-level paralle...
