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 method, system, and apparatus for preventing input/output (I/O) adapters used by an operating system (OS) image, in a logically partitioned data processing system, from fetching or corrupting data from a memory location allocated to another OS image within the data processing system is provided. A hypervisor prevents transmission of data between an input/output adapter in one of the logical partitions and memory locations assigned to other logical partitions during a direct memory access (DMA) operation by assigning each of the input/output adapters a range of I/O bus DMA addresses. The I/O adapters (IOAs) are connected to PCI host bridges via terminal bridges. A single terminal bridge may support multiple IOAs, in which case every terminal bridge has a plurality of sets of range registers, each associated with a respective one of the IOAs to which it is connected. An arbiter is provided which selects one of the input/output adapters to use the PCI bus. The terminal bridge can examine the grant signals from the arbiter to the IOAs, to determine which set of range registers is to be used.

摘要： A method and implementing system is provided in which system bridge circuits are enabled to execute, or over-commit to, transaction requests from system devices for information transfers which exceed the bridge circuit's current capacity to receive the requested information on its return from a designated target device such as system memory or another system device. The transaction request is moved along the data path to the designated target device and the requested information is returned, in an example, to the requesting device. By the time the requested information is returned to the requesting bridge circuit, a number of the holding buffers usually have been freed-up and are available to accept and pass the information to the requesting device. In an illustrated embodiment, the amount of over-commitment is programmable and the amount of over-commitment to transaction requests may be automatically adjusted to optimize the information transfer in accordance with the particular system demands and current data transfer traffic levels.

摘要： A method and implementing computer system are provided in which bridge buffers are grouped together in a pool, and are dynamically assigned and unassigned to adapter devices as needed during information transfers. In an exemplary peripheral component interconnect (PCI) system embodiment, a PCI Host Bridge (PHB) is coupled to a first PCI bus and one of the devices of the first PCI bus is occupied by a PCI-PCI bridge (PPB) which couples the first PCI bus to a second PCI bus. An assignment of PHB buffers in the PHB is made relative to the number of PCI devices which are connected both directly and indirectly to the first PCI bus. Devices on both the first and second PCI busses are given approximately equal status in the buffer assignment process. Upon a completion of a data transfer to or from any one of the adapters, the freed-up buffers which were assigned to that particular adapter are dynamically reassigned to other adapters as needed to optimize use of all of the buffers in the PHB pool.
