Abstract:
1. A data processing method in a data processing system including an external storage and a data processing server that couples to the external storage and the data processing server includes a main memory and processes data in the main memory, the method comprising the steps of: a system controller of the data processing server is activated on the main memory by an OS activated by the data processing server, and independent of whether processing of the data is requested or not, executing a data processing control unit which receives, from the system controller, a request of the processing of the data in parallel with execution of a data loading control unit which continuously reads and loads onto the main memory a series of data including the data stored in a descending order of reference probability on the external storage; and if the data corresponding to the request for processing is not loaded into the main memory by execution of the data loading control unit, executing a process corresponding to the request of the processing for the data loaded on the main memory by the data processing control unit, after the data is loaded into the main memory by the data loading control unit; wherein in response to entry of a system end command, the system controller making the data processing control unit end data processing, and executing an unloading control unit which unloads the series of data from the main memory to the external storage; wherein the unloading control unit calculates the reference probability which is acquired based on at least one of an input information from an input device coupled to the data processing server and a statistical information related to the processing of the data; and wherein the unloading control unit unloads, in the descendent order of the reference probability, the series of data including the data onto the external storage from which data is read out continuously in the descendent order of the reference probability by the data loading control unit.
