    摘要： To an existing instruction set, newly added are a condition code conversion instruction for converting a first condition code (N, Z, OV, C) to a second condition code (V, S) based on a reference condition code COND, a second conditional instruction having a reference flag SF, and an instruction of operation between two selected second condition codes. A VLIW processor comprises a second condition code register file 163, a condition code conversion circuit 12A, and a logic operation circuit 12E for performing a non-Boolean logic operation between two selected second condition codes.

    摘要： An internode put requesting unit detects a time-out with respect to a put request issued to the next node in the order of a multiplexing chain and notifies a put/get executing unit of the time-out. The put/get executing unit sends an error to the previous node in the order of the multiplexing chain or a client and instructs a put-failed-data synchronizing unit to synchronize data failed to be put, and the put-failed-data synchronizing unit performs a synchronization process. A primary makes other put requests wait until completion of the synchronization process. Furthermore, when having received the error, the client issues a get request to the tail end of the multiplexing chain.

    摘要： An access method includes: obtaining, by a computer, a result of monitoring a busy rate and a number of access operations per unit time of a storage device, the storage device having a first storage area and a second storage area; calculating a characteristic of correlation between the busy rate and the number of access operations per unit time based on the result; calculating a second number of access operations per unit time based on the characteristic of the correlation such that a sum of a first busy rate corresponding to a first number of access operations per unit time and a second busy rate corresponding to a second number of access operations per unit time becomes equal to or lower than a given busy rate; and controlling a number of operations to access the second storage area per unit time based on the second number of access operations.

    摘要： A file server has a conversion table that stores therein, in a corresponding manner, logical addresses specified by a higher-level layer and physical addresses specified by a disk driver that are address information indicative of a storage area in a disk device. The file server accesses the disk device with a storage area indicated by a physical address as an access destination and counts up the number of access requests to each storage area in a given period of time for each of the logical addresses. The file server then updates the conversion table such that the physical addresses are lined up in a descending order of the logical addresses of a higher number of the access requests counted. Thereafter, the file server changes storage areas of data stored in the storage device based on the conversion table updated.

    摘要： A migration program which reduces a service suspension time, ensures access transparency and position transparency, and enables normal operation without degrading the performance. When processing is migrated from a source computer, an operating reception block receives an operating system program through a network. An execution information reception block receives execution information needed to resume a process of the source computer, through the network from the source computer. An address reception block receives a floating MAC address assigned to the source computer in addition to the inherent MAC address, from the source computer. A processing block executes processing to restore the state of the source computer in accordance with the received operating system program and execution information, and performs subsequent communication by using the received floating MAC address of the source computer.

    摘要： An information processing apparatus includes a first storage unit and a processor. The first storage unit includes a first storage area. The processor receives a first request to write first data into the first storage area. The processor requests an external apparatus to write the first data into a second storage area in a second storage unit included in the external apparatus. The processor determines whether a first response has been received from the external apparatus. The first response indicates that the first data has been written into the second storage area. The processor writes the first data into the first storage area when the first response has been received. The processor requests, without writing the first data into the first storage area, the external apparatus to write second data stored in the first storage area into the second storage area when the first response has not been received.
