    摘要: A networking apparatus has its switching unit set a path for a data transfer from a processing apparatus on the data origination side to a processing apparatus on the data termination side. In case of a stop in the processing apparatus on the data origination side during the data transfer, the networking apparatus has its offline status detecting unit detect the stop by the presence or absence of an online status indication signal from the processing apparatus on the data origination side and generate an offline status indication signal. The networking apparatus has its controlling unit receive the offline status indication signal, and generate a simulated end-of-data signal, indicating a consummation of a data transfer, for transmission to a switching unit. The networking apparatus has its switching unit detect an end of data by receiving the simulated end-of-data signal, and cancel the path for the data transfer from the processing apparatus on the data origination side to the processing apparatus on the data termination side.

    摘要: In a parallel data processing control system for a parallel computer system having a plurality of computers and an adapter device connecting the computers to each other, a first unit, which is provided in the adapter device, transfers pieces of data processing progress state information to the computers. The pieces of the data processing progress state information respectively indicate data processing progress states of the computers. A second unit, which is provided in each of the computers, holds the pieces of the data processing progress state information. A third unit, which is provided in each of the computers, holds management information indicating a group of computers which share a data process. A fourth unit, which is provided in each of the computers, determines whether or not the computers in the group have completed the data process on the basis of the pieces of the data processing progress state information and the management information.

    摘要: A request cancel system is incorporated in a processing system which includes a main storage unit having a plurality of banks, a memory control unit and a plurality of access units, such as central processing units (CPUs), which access the banks of the main storage unit via the memory control unit. A check part in the request cancel system detects whether or not a bank designated by an address of an access request from one of the access units is in use by reading a corresponding bank busy flag from a bank busy flag group. After the check part has determined that a bank designated by an address of a first access request is not busy, a flag is sent to the bank busy flag group to indicate that the bank accessed by the first access request is busy. A second access request to the bank accessed by the first access request can be processed by the check part before the flag is set in the bank busy flag group. A comparator compares the addresses of the first access and second access requests and outputs a coincidence signal when the addresses of the first and second access requests coincide. A request cancel controller cancels the second access request in response to the coincidence signal from the comparator.
