摘要： An administrative computer which is connected to a plurality of search execution computers, includes: a distributed administration manager which receives graphs which retains a relation which connects data value and is configured with a group which is connected by the relation, and distributes same among a plurality of search execution computers; and a distributed search manager which, when a search condition is received, transmits the search condition to the plurality of search execution computers, and receives search results. The distributed administration manager groups the graphs with matching relations, segments the graphs which is associated with the group, and positions same on the plurality of search execution computers. The distributed search manager transmits search conditions including search conditions of the relations between the data and search conditions of the data value to each of the plurality of search execution computers, and has the search executed in parallel.

摘要： A computer capable of managing reference relationships between data executes access of first and second storage regions in which stored data can be altered and a third storage region in which stored data cannot be altered. The computer sets specification data in the first storage region for accessing data stored in the second and third storage regions, and shifts data having a reference relationship with the specification data from among the data stored in the third storage region to the second storage region. If the accessing occurs while the shifting is being carried out and the data has already been shifted to the second storage region, the reference information for the specification data is amended to the shifted location of the data, and all of the references to data in the third storage region that are referenced by the specification data are amended, thereby releasing the third storage region.

摘要： Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released.

摘要： A memory management method is provided to manage a memory in which areas of a garbage collected Java heap memory and a non-garbage collected external heap memory can be secured, by using a program executed by a processor in a computer. If it is judged that there is no reference to all data arranged in the external heap memory or starting point data of reference relations included in the all data, from data arranged outside the external heap memory, then the external heap memory is judged to be capable of being deallocated. As a result, it becomes possible to implement memory management in which garbage collection needing a long time program stop is not conducted and an additional API is not used.

摘要： To improve the execution performance of a program which makes indirect array reference by performing data prefetching also on an indirect reference array while reducing an instruction overhead, locality in data reference which cannot be detected by a conventional compiler is enabled to be detected by a user instruction or analysis by a compiler on the basis of a tendency that values of indices in an indirect reference array monotonously increase or decrease. By using the information, issuing of redundant prefetch instructions is suppressed, and data prefetching is enabled to be performed also on an indirect reference array.

摘要： The present invention provides a memory access optimizing method which judges an access method suitable for each of memory accesses and executes the preload optimization and prefetch optimization, according to the judgement result, for an architecture equipped with a prefetch mechanism to write the data on a main storage device into a cache memory and a preload mechanism to write the data on the main storage device into a register without writing it into the cache memory. The memory access method judging step analyzes whether or not there is a designation of a memory access method by a user. Moreover, the memory access method judging step investigates whether or not the data are already in a cache memory, whether or not the data compete with other data for a cache, whether or not the data are to be referred to again later, and whether or not the data fulfill the restriction on register resources.
