Abstract

The invention discloses a domestic computer cluster-based parallel computing system and method. The method comprises the steps of setting a control node used for receiving a job submitted by a user, setting a total divisible parallel task quantity of the job to be m, and according to the demands of the job, determining required computing node quantity N and computing core quantity n; distributingthe job to N computing nodes, performing parallel computing by n computing cores, and after the n computing cores finish calculation, transmitting n intermediate calculation results to a master computing node for performing summarization, wherein each computing core is in charge of computing m / n computing tasks; classifying control nodes into a master control mode and standby control nodes, enabling the master control node and the standby control nodes to manage and monitor states of the cluster computing nodes and a running state of the job at the same time, and when the master control node has a software fault or hardware crashes, taking over work of the master control node by the standby nodes; and adaptively installing domestic Kylin operating systems in the control nodes and the computing nodes.

Description

technical field [0001] The invention relates to a parallel computing system based on a computer cluster, in particular to a parallel computing system based on a localized computer cluster. Background technique [0002] With the continuous popularization of the Internet, massive amounts of data are being generated all over the world. Statistical analysis of the massive data generated can dig out meaningful information from the seemingly messy data, thereby creating economic value. At the same time, the generation of data is growing at a speed close to geometric progression, which places a huge demand on computing power. However, limited by Moore's Law of semiconductors, the main frequency and computing power of CPU cores cannot be improved by leaps and bounds, and the number of cores integrated by a single computing node CPU is also limited. Therefore, it is very necessary to develop a parallel computing method with multiple computing nodes. A computer cluster is a computi...
