摘要： A computing system includes a processing system, at least a first register, and a control system. The processing system generates a first instruction set and a first address for storing a first completion status for the first instruction set. The first register receives the first address from the processing system. The control system communicates the first instruction set received from the processing system to an external device. The control system receives the first completion status from the external device, accesses the first register to determine the first address for the first instruction set, and stores the first completion status in the determined first address.

摘要： A clustered computer system, bridge device and method include support for an atomic ownership change operation that ensures orderly and reliable ownership management of an input/output (I/O) bridge device. A lock indicator is associated with a bridge device, and is used to indicate a “locked” or “unlocked” status of the bridge device. Whenever the lock indicator indicates that the bridge device is unlocked, an atomic operation such as a read request to a lock indicator register is utilized to both set the indicator to indicate a locked status for the bridge device, and to associate the bridge device with a source node that initiated the atomic operation. In connection with the lock indicator, write access to one or more configuration parameter registers is controlled such that only the node that is associated with the bridge device is permitted to update such configuration parameter registers.

摘要： A circuit arrangement, node, clustered computer system, and method incorporate a primitive communication mechanism for use in exchanging data between adjacent nodes coupled via a point-to-point network. A plurality of network ports are used to couple a node to other nodes in the clustered computer system over point-to-point network interconnects, and a plurality of communication registers are associated with each of the network ports for the purpose of storing data received through their associated network ports. A node desiring to communicate information to another node receives a port identifier from the other node that identifies the network port on the other node through which the pair of nodes are coupled. The port identifier is then used by the node to communicate data to the other node through the use of one or more write operations directed to the communication register on the other node that is associated with the network port identified by the port identifier. On the other node, a control circuit is used to automatically notify the other node whenever data is stored in any of its communication registers, e.g., by generating an interrupt in response to non-zero data being stored in any of such communication registers.

摘要： An aliased queue pair is provided within a logically partitioned data processing system for each logical partition for the single general services management queue pair that exists within a physical host channel adapter. Packets intended for the logical ports are received at the physical port. Multiple partitions exist within the data processing system. When one of these partitions needs to use one of the logical ports, a queue pair is selected. The queue pair is then associated with the logical port. The queue pair is configured as an aliased general services management queue pair and is used by the partition as if the aliased queue pair were the single general services management queue pair provided in the channel adapter.
