Abstract: The stock exchanged in stock quotation system is especially multitudinous and must be processed real-time and promptly. Meanwhile the results of the data need be showed quickly. In order to resolve the contradiction between the requirement for the processing speed and multitude of data, the system has adopted multiple process running parallel in the network communication and the data exchange. The synchronous mechanism is used among the processes to coordinate. The actual application has proved that the effect is very nice and display speed has been raised greatly (The display time is less than 1 s).

Key words: stock quotation； multitude process running parallel； the network communication； the synchronous mechanism of multiple
