摘要:
An information processing system includes a first processor having a first local memory, a second processor having a second local memory, and a third processor having a third local memory. The system further includes a unit which maps one of the second and third local memories in part of an effective address space of a first thread to be executed by the first processor. The mapped one of the second and third local memories is the local memory of a corresponding one of the second and third processors, which executes a second thread interacting with the first thread. The system also includes a unit that changes a local memory to be mapped in part of the effective address space of the first thread from the one of the second and third local memories to the other.

摘要:
In a data transfer scheme using a caching technique and/or a compression technique which is capable of reducing the network load of a network connecting between data transfer devices, correspondences between data and their names are registered at the data transfer devices and the corresponding names are transferred, instead of transferring the data, for those data for which the correspondences are registered, so that it is possible to reduce the amount of transfer data among the data transfer devices. Server side data transfer devices and client side data transfer devices can be provided in multiple-to-one, one-to-multiple, or multiple-to-multiple manners.

摘要:
In a data transfer device, presence/absence of a prescribed header in the received request message is analyzed, and information indicating the presence/absence of the prescribed header, or information indicating either presence or absence of the prescribed header when the prescribed header is either present or absent as a result of analysis is stored. Then, when a reply message corresponding to the request message is received, the presence/absence of the prescribed header is checked by referring to the stored information, and the reply message is transferred according to a result of checking.

A device control apparatus includes a processor that operates according to software, a storage unit that stores privileged software which manages an interrupt to the processor from a device included in the device control apparatus, an OS storage unit that stores an Operation System for calling the privileged software from the storage unit when an interrupt from the device is detected during an execution of the software, a detecting unit that detects an interrupt to the Operation System from the device while the Operation System is operating on the processor, a judging unit that judges whether the Operation System has called the privileged software from the storage unit in a first predetermined time from detection of the interrupt to the Operation System from the device, and a resetting unit that resets the processor when the judging unit judges that the Operation System has not called the privileged software from the storage unit.

An access control apparatus includes a writer syndrome generator that generates a writer syndrome of writer mask data to mask the parity-added data, the writer syndrome being associated with a writer access ID used when a writer that requests writing of the write data in the memory accesses the memory; a write mask generator that generates the writer mask data based on the writer syndrome, the writer access ID, and a write address in the memory at which the writer writes the write data; a first XOR calculator that obtains first post-operation data by calculating an XOR between the parity-added data and the writer mask data; and a write address converter that converts the write address into another address determined by the writer access ID.

A processor communicating with a first memory configured to store first information and first data, and communicating with a second memory configured to store second information and second data, includes a computing unit configured to perform computation using the first data and the second data; an storing unit configured integrally with the computing unit to store first authentication information and second authentication information; a reading unit configured to read out the first information and the second information; an authenticating unit configured to authenticate the first memory by comparing the first information and the first authentication information, and to authenticate the second memory by comparing the second information and the second authentication information; and an controlling unit configured to control an access of the computing unit to the first memory and the second memory based on a result of the authentications.
摘要:
In an information processing apparatus, when an instruction is issued to write back storage contents of a main memory unit that is non-volatile, data and a write destination address included in a backup data that is set with a read permission are extracted from the backup data stored in a backup memory unit that is non-volatile. Further, according to the data and the write destination address extracted from the backup data, the data is written to a storage area of the main-memory unit indicated by the write destination address.
