An information processing apparatus including a communication interface to communicate with another information processing apparatus, and a processor that executes a process including issuing, by a first thread, a reception request of data from the another information processing apparatus to the communication interface, determining, by using the first thread, whether a completion notification is stored in a queue that stores data transmitted from the other information processing apparatus, causing the first thread to transit to a suspended state when the completion notification is not stored, executing a processing by using a second thread included in the plurality of threads when the first thread is in the suspended state, determining whether the completion notification is stored in the queue after the processing, and transferring the received data to the first thread and causing the first thread to return from the suspended state, upon a storing of the completion notification.

Information processing apparatus, information processing method, and non-transitory computer-readable storage medium

An information processing apparatus including a memory that stores correspondence information, the correspondence information indicating a correspondence between a plurality of first identifiers and a plurality of combinations of one of a plurality of first threads and one of a plurality of second threads, respectively, and a processor coupled to the memory and the processor configured to execute a process including storing, into a queue, a completion notification corresponding to received data upon a reception of the received data, the received data including a second identifier indicating a combination of transmission source thread among the plurality of second threads and a destination thread among the plurality of first threads, retrieving the completion notification stored in the queue, specifying a third thread among the plurality of first threads based on the second identifier included in the received data and the correspondence information, and transmitting the received data to the third thread.

A processor generates stream information indicating a stream of access on the basis of the positional relationship on a storage device among a plurality of accessed first data blocks. The processor associates sequence information representing the positional relationship on the storage device with a plurality of second data blocks prefetched in a memory on the basis of the stream information. When a certain second data block is accessed, the processor searches for another second data block that is determined to be earlier in the order of access made by the stream than the certain second data block, on the basis of the sequence information. The processor removes the found second data block from the memory.
