Information processing system, and control method

摘要

A control method for a control device which connects, via a connecting device, each of a plurality of processors that each executes processing to at least one of a plurality of memory devices that each stores data, the control method comprises controlling the connecting device so that a second memory device, which is one of the plurality of memory devices, is connected to the first processor in response to a connect request issued by a first processor, which is one of the plurality of processors, since a predetermined amount of data has been written into a first memory device, which is one of the plurality of memory devices, the control device; and controlling the connecting device so that the first memory device is disconnected from the first processor in response to a disconnect request issued by the first processor after starting to write data into the second memory device.

主权项

1. An information processing system comprising:
a plurality of processors; a plurality of memory devices; a connecting device that connects each of the plurality of processors to at least one of the plurality of memory devices; and a control device that controls the plurality of processors and the connecting device, wherein a first processor, among the plurality of processors, is configured to:
write data into a first memory device, among the plurality of memory devices, andtransmit a connection request for requesting the control device to connect a second memory, among the plurality of memory devices, with the first processor when it is determined that an amount of data stored in the first memory device exceeds a predetermined threshold, the control device is configured to control the connecting device to connect the second memory device with the first processor when the connection request is received, the first processor is configured transmit a disconnection request for requesting the control device to disconnect a connection between the first memory device and the first processor when the first processor starts writing data into the second memory device, the control device is configured to control the connecting device to disconnect the connection between the first memory device and the first processor when the disconnection request is received, and the controller device is configured to select a memory device, from among the plurality of memory devices, in which an oldest data is stored, when the connection request is received and it is determined that an unused memory device in which data are not stored does not exist in the plurality of memory devices and to connect the first processor with the selected memory device.
