Abstract

Power system has higher and higher requirement on equipment miniaturization, intelligence and reliability with growing demand for high-performance computing requirements. Conventional substation automation system has many deficiencies in the application, which can not meet power grid development and electricity market needs. Meanwhile, since communication software client can be connected with server, real-time binary data can be received, and data tabular form can be analyzed. Multi-core processor is widely popularized in high-performance computing. Balance between computing and communications should be maintained in order to ensure efficiency of high-performance computer system, widespread use of multi-core has higher requirement on system efficiency. Collective communication is regarded as an important part in multi-core communication system, research of efficient collective communication under multi-core environment has very important significance. Therefore, multi-threaded realization process based on TCP/IP protocol communication under client/server mode is mainly discussed in the paper, timing diagrams and activity diagrams are adopted for concrete description. The author discusses how to solve client crash problem, asynchronous data between client and server, and few data, influence of competition is lowered, collective communication performance and scalability under multi-core environment is improved, and it is proved that the system can be operated well according to test.
