Abstract: A rule storing unit stores a set of rules each defining facts and a relation between the facts, and weights representing importance levels of the rules. An input data storing unit stores input data. A query storing unit stores a query. An importance level calculating unit calculates an importance level of each fact type of the facts defined by the rules. A fact data generating unit generates, for each fact type, fact data in which true/false is observed as a fact by a number corresponding to the importance level of the fact type, from the input data. A fact data storing unit stores the fact data. An inference performing unit performs probabilistic inference of a result of the query by using the fact data, the rules, and the weights. An output unit outputs a result of the inference.

Abstract: A local-memory side data transfer unit increments the number of addresses, reads out data from a local memory, and stores the data into a cache memory of a remote-memory side data transfer unit. For preventing data mismatching with the local memory from being stored into the cache memory, a cache clearing operation is executed in units of an elapse of a round trip time period for data transfer between the local memory and the remote memory. Alternatively, the cache clearing operation is executed upon receipt of a signal notifying data transfer of data stored at a specified address.
Abstract translation: 本地存储器侧数据传送单元增加地址数量，从本地存储器读出数据，并将数据存储到远程存储器侧数据传送单元的高速缓冲存储器中。 为了防止与本地存储器的数据不匹配被存储到高速缓冲存储器中，以本地存储器和远程存储器之间的数据传送的往返时间周期为单位执行高速缓存清除操作。 或者，在接收到通知数据传送存储在指定地址的数据的信号时执行高速缓存清除操作。

Abstract: This accelerator control device includes: a decision unit which, in processing flow information representing a flow by which a task generated according to a program executed by an accelerator processes data, decides, from among the data, temporary data temporarily generated during execution of a program; a determination unit which, on the basis of an execution status of the task by the accelerator and the processing flow information, determines, for every task using the decided data among the temporary data, whether or not execution of the task has been completed; and a deletion unit which deletes the decided data stored in a memory of the accelerator when execution of every task using the decided data has been completed, whereby, degradation, of processing performance by an accelerator, which occurs when a size of data to be processed by the accelerator is large is avoided.
