Abstract: An information processing apparatus includes a memory, and a processor coupled to the memory and configured to acquire position information of regions of the memory where a correctable error occurs when detecting the correctable error over a predetermined number of times having a first value, specify, as software repair position information, position information having a frequency higher than the frequency of other position information among the acquired position information of regions, perform a software repair of a region indicated by the specified software repair position information, and confirm a presence or absence of an effect of the software repair of the region, and when the effect is determined to be present, set the software repair position information as hardware repair position information.

Abstract: An information processing apparatus includes a memory, a second processor, and a first processor. The second processor is configured to implement a virtual machine that accesses the memory. The first processor is coupled with the memory. The first processor is configured to read out first data from a first area of the memory. The first area is to be accessed by the virtual machine. The first processor is configured to store the first data in a cache of the first processor.

Abstract: An information processing apparatus includes: a VM including a driver that is configured to perform data input/output using an input/output device; a hypervisor configured to manage the VM and perform a synchronization process between the information processing apparatus and another information processing apparatus which form a pair; a monitoring unit configured to monitor an access made between a memory and the input/output device; a notification unit configured to notify the hypervisor of detection of a reading access in a case where the reading access relating to data output from the memory to the input/output device is detected by the monitoring unit; and a suppression unit configured to suppress the data output in a case where the hypervisor is in the middle of execution of the synchronization process when the hypervisor receives the notification from the notification unit. Accordingly, the input/output access performance of the VM is improved.

Abstract: A pseudo I/O system and method, which can be configured at low cost and simulates an actual I/O device by making a connection to a device to be tested, is configured by a setting unit defining error contents of a simulation target and setting the contents in a setting file; a receiving unit receiving a command from a device to be tested; a pseudo I/O unit processing the command received by the receiving unit if contents corresponding to the command are set when referencing the setting file, and performing a normal reply process if the contents corresponding to the command are not set; and a transmitting unit returning data after being processed to the device to be tested at a request source.

Abstract: A device driver apparatus, which can be configured at low cost, implements various types of tests while making a process perform the same operations as those of an actual I/O device in use. The device driver apparatus is configured by comprising an adapter which transmits or receives signal or data between an initiator and a pseudo process simulating an I/O device connected via a bus using a predetermined protocol, and a driver which is arranged between the adapter and the pseudo process simulating the I/O device, notifies the pseudo process of one or more of command and data from the adapter, and also notifies the adapter of one or more of status and data from the pseudo process. With this low-cost configuration, various types of tests can be conducted while making a process perform the same operations as those of an actual I/O device in use.
