摘要： PURPOSE:To evade the congestion of messages and to provide efficient full-to- full communication system in a network control system where the full-to-full communication is executed with high efficiency in a multiprocessor system which contains plural processors connected to each other vie a connection net having the torus type topology. CONSTITUTION:If the circumference of a torus is defines as (k), (n) is defined as k/2 with an even (k) and as (k+1)/2 with an odd (k) respectively. Under such conditions, the connection pattern of a switch box contained in a processing element 1 is controlled so that a state (n-1, n-1, n-1) is scanned from a state (0, 0, 0) for a torus type network. Thus a processing means can process the messages in a full-to-full communication way.

摘要： PURPOSE:To realize an inter-process communicating means which can perform efficient duplex communication without increasing the amount of the hardware. CONSTITUTION:In an information processor provided with a means which assigns communication links to logical channels in a system in which two processes for making outputs and inputs are synchronized by making communication to each other by using one logical channel and protocol fixed to the logical channel, a pair of duplex links used for inter-process communication is provided and, at the same time, synchronization detecting mechanisms 3, 4, 8, and 9 which detect the synchronization between the processes from a communication request from one process and the information related to the communication request from the other process obtained from the synchronization detecting mechanism of the other process and means 7, 12, and 13 which give the using right of the duplex links to a relevant process on the basis of the information related to the synchronization between the processes from the mechanisms 3, 4, 8, and 9 are provided on both ends of the duplex links.

摘要： PURPOSE:To avoid overhead due to message wait and to execute full point to pull point communication at high speed by building up a network comprising n-dimension switch box group of multi-stage constitution according to binary n-cube as topology. CONSTITUTION:As a network topology, plural switch boxes 10-1-10-4 are connected in multi-stage according to n-dimension binary n-cube. Each of the switch boxes 10-1-10-4 detects the passing of a message by using tag information E provided to the end of a message and when number of times of detection of message passing reaches a prescribed value, the switch state is subject to switching control by a switch control means 14. Thus, a message applied to the network via nodes 0-3 has always the same path length independently of the phase deciding the switching state of the switch boxes 10-1-10-4. Thus, overhead of message waiting is avoided and full point to pull point communication is implemented at high speed.

摘要： PURPOSE:To eliminate the misdetection of deadlocks, by judging it as a true deadlock when the time zone from a queuing relation generating time to a reporting time held by queuing relation information is certainly overlaped about each transaction. CONSTITUTION:When the queuing relation is produced between transactions T1 and T2 at a site 1, the state waiting for lock release is reported to a deadlock detecting mechanism 5, but the time when the waiting state is produced and reproting time to the deadlock detecting mechanism 5 are included in the report. The mechanism 5 checks the report together with queuing relation information from other sites 2 and 3 and whether or not the time from the queuing relation generating time to the reporting time overlaps about each transaction by taking the error of a clock into consideration. When the time overlaps, the mechanism 5 decides that the deadlock is not a ghost deadlock, but a true deadlock.

摘要： PURPOSE: To average a load on a processor of each node by allowing an identifier to discriminate immediately whether a received message is a message received before or not and executing the processing whether or not the message is to be transmitted to other nodes.
CONSTITUTION: The address of a broadcast message BM is confirmed by a reception section 21 and when it is addressed to the own node, the message is received. The message reaching first in the messages BM stored in a storage section 22 is extracted from the storage section 22 and set to a discrimination section 23. Then the message is compared with all identifiers stored already, and whether or not they are coincident is discriminated and when they are coincident, it is discriminated that the message is received again via other route. When dissident, since the said message is received newly, a host computer fetches the message and applies a prescribed processing and the identifier is stored newly in an identifier storage section 24. Then the message BM after processing is transmitted to an adjacent node by using a transmission section 25.

摘要： PROBLEM TO BE SOLVED: To reduce labor and time for retrieval and to quickly execute clustering processing by dividing a vector set to be clustered into a multi- dimensional(MD) tree. SOLUTION: The system is provided with a chain buffer 2 for registering records most close to each other, a vector storing table 5 for storing a vector set stored into respective leaves of an MD tree, an index table 3 and a next pointer table 4 which are linked with the table 5 and used for indicating a vector set housing the number of records equal to the number of records to be keys, and record management information 6. A clustering processing part 1 repeats such a processing as sorting a vector set by the MD tree, finding out records most close to each other while referring to the table 3 and the information 6, successively registering these records in the buffer 2, and preparing a vector set by merging vector sets most close to each other to execute clustering processing.

摘要： PROBLEM TO BE SOLVED: To make it possible to execute clustering processing even when data to be processed or intermediate data necessary for the processing are overflowed from a main storage. SOLUTION: A file 6 for storing records to be processed and a temporary file 7 for storing chain data are included in a secondary storage device 20 and an input buffer 2 for storing a part of records, an output buffer 3, record management information 4 for managing respective records stored in the file 6, and a chain buffer 5 for storing chain data are included in a main storage device 10. When a record necessary for processing is not stored in the main storage device 10 at the time of processing, a clustering processing part 1 inputs data including the record from the file 6 to the input buffer 2 and executes the processing, and when the output buffer 3 is filled with records, stores records overflowed from the buffer 3 in the file 6 and stores a processed record in the buffer 3.
