摘要： A computer includes first and second processors, first and second I/O devices, a shared memory, and an interrupt controller. The first processor issues a control command for causing the first I/O device to read target data from the first apparatus and store the target data in the shared memory. The first I/O device reads the target data from the first apparatus and, transfers the target data to the shared memory, and generates an I/O complete interrupt. The interrupt controller delivers the generated I/O complete interrupt to the second processor. When the second processor receives the I/O complete interrupt, the second processor issues a control command for causing the second I/O device to read the target data from the shared memory and send the target data to the second apparatus. The second I/O device reads the target data from the shared memory and sends the target data to the second apparatus.

摘要： Under the environment where a storage system is virtualized by Thin Provisioning technology or the like, it is difficult to statically estimate the I/O characteristics of the entire virtual volume, causing a problem that the effect of input/output control by a computer cannot be fully achieved by I/O scheduling that is based on the characteristics of a virtual volume unit. To solve the above problem, the computer system of the present invention acquires characteristics information of a storage apparatus in which there exists an actual storage area corresponding to a virtual volume storage area that is the access target when accessing the virtual volume, divides an I/O request with respect to the virtual volume by storage apparatus in a case where the I/O request spans multiple storage apparatuses, carries out I/O scheduling based on the acquired actual area characteristics information, and issues the I/O request directly to the storage apparatus in accordance with the I/O scheduling result.

摘要： Stream data is transmitted from a distribution server to a client without any loss of data. The capacity of a reception buffer to be prepared at the client can be made small and the network bandwidth necessary for data redistribution can be narrowed. A relay server interposed between the distribution server and client buffers stream data in an auxiliary storage device. When the relay server or client detects a loss of stream data, a redistribution request is transmitted to the distribution server or another relay server at the preceding stage.

摘要： A periodic process scheduling method which includes receiving requests for periodical execution of processes each with a period of execution and execution time, securing allocation time for the shortest process to be executed in respective periods of execution, securing another allocation time for part of a process if full execution time of the process cannot be secured within the respective periods of execution, and starting execution of the process in secured allocation time. A data transfer management method for reducing collision in data transfer which includes storing data length of packets being transferred in a predetermined transmission time interval, storing the predetermined transmission time interval, accumulating a quantity of packets to be transferred in the predetermined transmission time interval, and limiting quantity of packets to be transferred to not be greater than data length.
