摘要： A multiprocessor system can reduce a broadcast for cache memory consistency control with memory access from an I/O device. The multiprocessor system is provided with a cache memory identifier or an owner tag, and a block length table for recording a memory write block length of the I/O device. The cache memory identifier records that the cache has an exclusive copy. The owner tag records that there is no cache memory having an exclusive copy. If there is an exclusive copy during read through the I/O device, a read request is issued to both a cache holding the copy and a memory. If it is recorded that the copy is not present, data are directly read from the memory. Moreover, when a write block length is recorded in the block length table during write, whole blocks are collected to issue a request for invalidation from the cache and the request is directly written to the memory after the invalidation is completed.

摘要： Parallel processors communicate with each other over a network by transmitting messages that include destination processor information. A message controller for each processor in the network receives the messages and checks for faults in the message, particularly in the destination processor number contained in a first word of the message. If a fault occurs in the destination processor number, then the faulty message is transmitted to an appropriate processor for handling the fault. In this way the network operation is not suspended because of the fault and the message is not left in the network as a result of the error occurring in the destination processor number. The processor to which the faulty message is directed is determined by a substitute destination processor number contained in the message or is predetermined and set in another way, such as by a service processor. To recover from the fault, the processor receiving the faulty message can request that the message be retransmitted or the error can be corrected using an ECC, for example. If the faulty message cannot be retransmitted, then the processor or the host processor can request that the job to which the faulty message pertains be canceled by all of the processors executing that job without affecting the simultaneous execution of other jobs by the same processors.

摘要： A cache coherence control system for a multi CPU system having a plurality of CPU nodes, memory nodes and I/O nodes interconnected by a network. Each CPU node control circuit has an access right memory for managing an access right of the node in the unit of an extended node larger than a block size of the internal cache of a CPU. When a memory access is performed, the access right memory is referred to, and if the node has an access right to the extended block including a target block, the block is accessed without cache coherence control at other nodes.

摘要： In a parallel processor system comprising a plurality of processor elements constituting a network, a source processor element wishing to broadcast data to a plurality of destination processor elements sends a broadcast request message containing the target data to a broadcast exchanger. The broadcast exchanger converts the received message into a broadcast message and sends it over the network to the destinations. A plurality of broadcast request messages, if transmitted parallelly to the broadcast exchanger, are serialized thereby so that only one broadcast message will be transmitted at a time over the network. This prevents deadlock from occurring between different broadcast messages. The routes for transmitting broadcast request messages and those for transmitting broadcast messages are arranged so as not to overlap with one another. This suppresses deadlock between any broadcast request message and broadcast message. The broadcast exchanger is replaced alternatively with one of the partial networks. These schemes all apply where long messages are transmitted through worm-hole routing.

摘要： Crossbar switches having 2.sup.n +1 ports and computing clusters are arranged so that each crossbar switch is connected to 2.sup.n processors. Auxiliary processors that perform parallel processing administrative functions and input/output functions are arranged at the remainder ports of the crossbar switches. Exchangers are provided to connect each processor and its crossbar switches. Parallel processing may be executed by the 2.sup.n processors independently of processing by the auxiliary processors for speed. One mounting unit is formed of a crossbar switch of one dimension, the processor group connected to that crossbar switch, and all of the crossbar switches of a different dimension that are connected to one of the processors of the one processor group. The parallel processor system is mounted by just combining mounting units with no need for special LSIs or frames or the like on which to mount the crossbar switches and without the interfaces that connect the processor and the network becoming concentrated in one place.
