摘要： A method in a network computing system for managing a plurality of subnet managers in the network computing system. An identification is received of a set of subnet managers within the plurality of subnet managers. The set of subnet managers is allowed to participate in a master election to select a master subnet manager. Subnet managers other than the set of subnet managers are placed in a dormant state. The master subnet manager is elected from the set of subnet managers through the master election, wherein other subnet managers within the number of subnet managers poll the master subnet manager to allow the other subnet managers to elect a new master subnet manager if the master subnet manager fails.

摘要： A method for managing allocation of network resources within the distributed computer system is provided. Specifically, the network traversal time and the end node response time for requests and/or packets being routed in a switch-connected system area network are utilized to determine the total round trip time for completion of the particular network operation. The sum of the timeout values for all switches that participate in routing the request from a requester (source) to the receptor node (target) is provided to the requester's channel adapter (CA). The time-out values are provided by the switch manufacturer and are sent to a network Subnet Manager (SM) via SM packets (SMP). The timeout values added together represent the SubnetTimeout. The time-out value of the target channel adapter (CA), the ResponseTime, is also provided to the requester. The requester then utilizes one of two timeout equations to calculate the overall response time required for the request to be completed. A timer is started and the elapsed time to complete the request is monitored and compared with the overall response time calculated. When the timer expires before a response is received at the requester, the operation is assumed to have failed and the network resources being utilized by the request may be reallocated to another network operation.

摘要： A method in a node within network computing system for selecting a master network manager, wherein the first node is associated with a first priority. Requests are sent to the network computing system to discover other nodes within the network computing system. A second priority from the request is identified in response to receiving a response to one of the requests from another node within the network computing system. The first node shifts to a standby mode if it discovers a master subnet manager or the second priority is higher than the first priority. The first node shifts to a master mode if a response containing a priority higher than the first priority is absent in responses received by the first node and the first node has completed checking all other nodes in the network computing system. In the case where the priority received is equal, the comparison is further made on the globally unique identifier which is received from the same node, in which case the node with the lowest globally unique identifier wins the arbitration.

摘要： A method in a node for managing authorized attempts to access the node. A packet is received from a source, wherein the packet includes a first key. A determination is made as to whether the first key matches a second key for the node. The packet is dropped without a response to the source if the first key does not match the second key. Information from the packet is stored in response to this absence of a match. The information is sent to a selected recipient in response to a selected event, which may be, for example, either immediately or in response to polling to see if the information is present.

摘要： A method for enabling a Q_key that is tamper proof from applications on a distributed computer system to protect selected network operations is provided. Applications and an operating system (OS) execute on the end nodes and each may access various network resources. In the invention, the network resources are configured for selective access by particular applications or OS.In a preferred embodiment, a control bit of a Q_key, which allows applications to authenticate their use of particular communication resources, i.e., the send and receive queues, is reserved and utilized to signal whether a particular application is allowed access to the resources. Setting the control bit to 0 allows the Q_key to be set by an application directly. When the control bit is set to 1, the Q_key cannot be set by an application and can only be set using a privileged operation performed only by the OS.

摘要： A bus bridge including a buffer pool and steering logic where the buffer pool is organized as a plurality of buffers sets including at least first and second buffer sets and the steering logic is adapted to store transactions originating with a first peripheral device in the first buffer set and transactions originating with a second peripheral device in the second buffer set. Transactions may arrive via a secondary bus, such as a PCI bus, coupled to the bus bridge. The bridge further allows relaxed transaction ordering rules compared to conventional PCI transaction ordering rules by identifying transactions by grant signals and thus allows steering of transactions from the first and second devices to first and second buffer sets respectively. The bridge is suitably adapted for combining or merging two or more transactions within each buffer set. Each buffer set preferably includes one or more buffers for temporarily storing transactions arriving from the secondary bus and bound for a primary bus. The primary bus may comprise a host bus connected to one or more processors or an additional PCI bus or other peripheral bus. The invention further contemplates a computer system including at least one processor, a bridge coupled to the processor via a host bus, and a plurality of peripheral devices including first and second peripheral devices coupled to the bridge via a secondary bus. In one embodiment, the bridge is configured to receive first and second request signals from the first and second peripheral devices respectively. The bridge preferably further includes arbitration logic for arbitrating mastership of the secondary bus in response to the request signals to produce first and second grant signals. The steering logic is suitably configured to utilize the first and second grant signals to determine the source of a subsequent transaction.

摘要： A bus bridge including a buffer pool comprised of a first and a second buffer sets. The first and second buffer sets are associated with first and second peripheral devices respectively. The bridge is configured to receive an interrupt and identify the interrupt source. A buffer set associated with the interrupt source is selected and transactions in the selected buffer set flushed prior to forwarding the interrupt to a processor. The bridge is preferably configured to identify the interrupt source by receiving a first interrupt signal from the first peripheral device and a second interrupt signal from the second peripheral device. Preferably, the bridge is configured to flush the transactions by pushing them into system memory via a primary bus such as a host bus of a processor. The invention further contemplates a system including a processor coupled to a host bus, a system memory, a bus bridge as described coupled between the host bus and a secondary bus, and first and second peripheral devices coupled to the secondary bus. Upon receiving an interrupt, the bridge is configured to identify the interrupt source, select a buffer set associated with the interrupt source, and flush posted memory write transactions in the selected buffer set, all prior to forwarding the interrupt to the processor. In one embodiment, the bridge, the first and second peripheral devices, and the secondary bus are compliant with the PCI specification. The bridge is configured in one embodiment to receive unique first and second interrupt signals from the first and second peripheral devices respectively.
