摘要： Provided is a computer system in which an I/O card is shared among physical servers and logical servers. Servers are set in advance such that one I/O card is used exclusively by one physical or logical server, or shared among a plurality of servers. An I/O hub allocates a virtual MM I/O address unique to each physical or logical server to a physical MM I/O address associated with each I/O card. The I/O hub keeps allocation information indicating the relation between the allocated virtual MM I/O address, the physical MM I/O address, and a server identifier unique to each physical or logical server. When a request to access an I/O card is sent from a physical or logical server, the allocation information is referred to and a server identifier is extracted from the access request. The extracted server identifier is used to identify the physical or logical server that has made the access request.

摘要： Each node includes a node controller for decoding the control information and the address information for the access request issued by a processor or an I/O device, generating, based on the result of decoding, the cache coherence control information indicating whether the cache coherence control is required or not, the node information and the unit information for the transfer destination, and adding these information to the access request. An intra-node connection circuit for connecting the units in the node controller holds the cache coherence control information, the node information and the unit information added to the access request. When the cache coherence control information indicates that the cache coherence control is not required and the node information indicates the local node, then the intra-node connection circuit transfers the access request not to the inter-node connection circuit interconnecting the nodes but directly to the unit designated by the unit information.

摘要： In a multiprocessor arranged in accordance with either NUMA or UMA in which a plurality of processor nodes containing a plurality of processor units are coupled to each other via a network, a cache snoop operation executed in connection with a memory access operation is performed at two stages, namely, local snoop operation executed within a node, and global snoop operation among nodes. Before executing the local snoop operation, an ACTV command for specifying only an RAS of a memory is issued to a target node having a memory to be accessed, and the memory access is activated in advance. A CAS of a memory is additionally specified and a memory access is newly executed after the ACTV command has been issued and then a memory access command has been issued. When there is such a possibility that a memory to be accessed is cached in a processor node except for a source node, this memory access command is issued to be distributed to all nodes so as to execute the global snoop operation. On the other hand, when there is no possibility that the memory to be accessed is cached, this memory access command is transferred only to the target node in yan one-to-one correspondence.
