Abstract
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.
