摘要： A method and apparatus for manipulating work queue elements via a hardware adapter and a software driver. The software driver is configured to cause a plurality of work queue elements to be stored in a queue pair including a plurality of storage locations. Each of the plurality of storage locations includes an indicator indicating whether a corresponding work queue element has been completed. The hardware adapter is configured to select one of the plurality of storage locations and to service a corresponding one of the plurality of work queue elements, and in response to completion of a task associated with the corresponding work queue element, to cause the indicator to indicate that the corresponding work queue element has been completed. Additionally, the software driver is configured to cause a new work queue element to be stored in the selected storage location in response to detecting that the indicator indicates that the corresponding work queue element has been completed.

摘要： A system and method for upgrading a computer is disclosed. Certain essential chips present in the original computer system are functionally, but not necessarily physically, removed from the computer system. Functions which would otherwise be performed by the original chips are instead performed by higher-performance chips on a plug-in module which is plugged into the computer system. The functional removal of the certain chips from the original computer system is achieved through simple insertion of the plug-in module. No replacement or substitution of original chips or boards is necessary. Furthermore, upgraded computer systems may be further upgraded by replacement of a first plug-in module with a second plug-in module with different performance characteristics.

摘要： An interrupt messaging scheme to manage interrupts within a multiprocessing computer system without a dedicated interrupt bus. An interconnect structure using a plurality of high-speed dual-unidirectional links to interconnect processing nodes, I/O devices or I/O bridges in the multiprocessing system is implemented. Interrupt messages are transferred as discrete binary packets over point-to-point unidirectional links. A suitable routing algorithm may be employed to route various interrupt packets within the system. Simultaneous transmission of interrupt messages from two or more processing nodes and I/O bridges may be possible without any need for bus arbitration. Interrupt packets carry routing and destination information to identify source and destination processing nodes for interrupt delivery. A lowest priority interrupt packet from an I/O bridge is converted into a coherent form by the host processing node coupled to the I/O bridge. The host node then broadcasts the coherent interrupt packet to all other processing nodes in the system regardless of whether a processing node is identified as a target in the interrupt message packet from the I/O bridge. The host node also receives responses from recipient nodes and coordinates lowest priority arbitration. In case of a fixed, an ExtINT or a non-vectored interrupt message from the I/O bridge, the host node simply forwards the interrupt packets to all other nodes in the system without performing the conversion. Inter-processor interrupts may also be delivered in a similar manner. Interrupt response is decoupled from corresponding interrupt message and the interrupt messaging protocol may be implemented independently of the physical properties of a system bus carrying interrupt packets.

摘要： An interrupt messaging scheme for a multiprocessing computer system where a dedicated bus to carry interrupt messages within the multiprocessing system is eliminated. Instead, an interconnect structure using a plurality of high-speed dual-unidirectional links to interconnect processing nodes, I/O devices or I/O bridges in the system is implemented. Interrupt messages are transferred as discrete binary packets over point-to-point unidirectional links. Various interrupt requests are transferred through a predetermined set of discrete interrupt message packets. Interrupt message initiators—an I/O interrupt controller or a local interrupt controller (in case of an inter-processor interrupt)—may be configured to generate appropriate interrupt message packets upon receiving an interrupt request. A suitable routing algorithm may be employed to route various interrupt messages within the system. Simultaneous transmission of interrupt messages from two or more interrupt controllers may be possible without any need for bus arbitration. Interrupt response is decoupled from corresponding interrupt message and the interrupt messaging protocol may be implemented independently of the physical properties of a system bus carrying interrupt packets. System flexibility in managing interrupts is thus improved.

摘要： An host channel adapter embedded within a processor device includes a transport layer module, a transport layer buffer, a link layer module, and a link layer buffer configured for storing at least two packets to be transmitted by the embedded host channel adapter. The transport layer module is configured for generating, for each packet to be transmitted, a transport layer header, and storing in the transport layer buffer the transport layer header and a corresponding identifier that specifies a stored location of a payload for the transport layer header. The link layer module includes payload fetch logic configured for fetching the payload based on the corresponding identifier, enabling the link layer module to construct one of the two packets to be transmitted concurrently during transmission of the second of the two packets.

摘要： A computing node configured for communications on an InfiniBand™ network includes at least two host channel adapters configured for communications on the InfiniBand™ network, and at least one processor configured for controlling the communications of the two host channel adapters on the InfiniBand™ network. The host channel adapters communicate with the processor via an internal bus. The processor monitors communication operations by the host channel adapters on the InfiniBand™ network. If the processor detects that one of the host channel adapters is unable to complete the corresponding communication operations, the processor outputs a message requesting traffic destined to the one host channel adapter to be redirected to the remaining host channel adapter.
