    摘要： In order to reduce load at a resource managing node for exclusive control of a shared resource, each node has a group of lock state registers each corresponding to one of the nodes. Before one node issues a lock request to a resource managing node, the node checks the register group to see if the resource managing node is unlocked. With the target node found to be accessible, the access requesting node sends to a broadcast message exchange circuit a broadcast request message including a lock request regarding the resource managing node. The broadcast message exchange circuit receives such broadcast request messages from access requesting nodes, and changes them serially into broadcast messages for broadcast to all nodes. Of these broadcast messages, the first message received by each node is processed by its lock control circuit so that the lock request in that message is allowed to lock the resource managing node. The lock control circuit writes the number of the access requesting node into the register corresponding to the resource managing node. The access requesting node checks the register contents to see if the lock request it issued has been successfully accepted.

    摘要： Disclosed are a virtual computer system and method, wherein computer resources are automatically and optimally allocated to logical partitions according to loads to be accomplished by operating systems in the logical partitions and setting information based on a knowledge of workloads that run on the operating systems. Load measuring modules are installed on the operating systems in order to measure the loads to be accomplished by the operating systems. A manager designates the knowledge concerning the workloads on the operating systems through a user interface. An adaptive control module determines the allocation rations of the computer resources relative to the logical partitions according to the loads and the settings, and issues an allocation varying instruction to a hypervisor so as to thus instruct variation of allocations.

    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.
