The amount scattered computer processing system cluster conversion model which prepares with soft real-time responsiveness and continual availability

摘要

(57) Abstract The amount scattered computer processing system has with the main server who possesses main hypothetical common memory and the backup server who possesses backup hypothetical common memory. The main server has tried to do offering the status table to the backup server periodically, hypothetical common memory and backup hypothetical common memory same period. The plural client computer resources through plex structure with to the main server and the backup server, it is connected. The client computer resource furthermore has plural worker processes, each has been adapted, tries to execute operation in independence concerning the data object which is placed inside main hypothetical common memory, with worker process and data object without specified appointment being done is executed. When the utilization impossibility of one side of the main server or the backup server exists, operation is executed concerning the data object where worker process was placed inside backup hypothetical common memory and corresponds. The client computer resource furthermore has plural input/the output (I/O) port, receiving the packet where this arrives, has tried to send out the data packet which keeps coming out.
