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 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 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 and system for efficiently merging subnets having individual subnet managers (SM) into a single network with one master SM. During discovery and configuration of a subnet, a subnet manager creates a Subnet Management Database (SMDB) representative of the subnet components being managed. Each subnet manager contains an independent SMDB. When two or more subnets are linked/connected together to form a single network, a single one of the subnet managers is selected as the master subnet manager and all the subnets' SMDBs must be merged. An SMDB record labeling mechanism is utilized to differentiate among components from the different subnets that may have the same parameter values, such as protection keys (P_keys) and re-assign individual parameters to create a single SMDB of uniquely defined components.

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： Systems and arrangements to adjust resource accessibility based upon usage modes are contemplated. Embodiments may include a supervisor instance such as an operating system that is adapted to select one or more supervisor keys from a set of supervisor keys available to the host node or platform upon which the supervisor instance is operating. The supervisor instance may select the supervisor key(s) based upon an association of the supervisor instance with a usage mode represented by a supervisor key name. In many embodiments, supervisor key names may be associated with resources via with one or more of the supervisor keys based upon the resources needed when operating in the usage modes by a system administrator. Once the supervisor instance is initialized, the supervisor instance may issue client keys that allow access to subsets of the resources available to the supervisor instance based upon usage modes of the clients.

摘要： A method, apparatus, and computer implemented instructions for transferring data. A request is sent by a requester to a responder. The request includes an amount of available processing space at the requestor. When the request is received from the responder, data is identified using the request. The data is placed into a plurality of subsequences of data packets for transfer to the requester, wherein each packet within the set of subsequences hold data in amount less than or equal to the amount of available space. These subsequences are then sent to the requestor one subsequence at a time. A new subsequence is sent each time the available processing space at the requester becomes free to process data from another subsequence. The requestor receives a subsequence from the plurality of subsequences in response to the request each time the amount of available processing space is free, wherein data within each of the set of subsequences fits within the amount of available processing space.

摘要： A system and method for establishing multiple connections using a private data field of a communication management protocol is provided. With the present invention, a Service ID identifies a specific consumer and the private data field contains a list of connection attributes for each connection that is to be established. An active side requests a connection and the passive side replies to the connection request. The active side sends the passive side a connection establishment request. This connection establishment request includes a Service ID which identifies a passive side process associated with a service. This connection establishment request also includes communication attributes of one or more connected services and datagram services associated with the Service ID. The passive passes the connection request to a process associated with the service. If the passive side process does not wish to carry out the service, a negative reply message is returned to the active side. If the passive side process does wish to carry out the service, a positive reply is returned to the active side and the reply includes the communication attributes for the connection and unreliable services associated with the Service ID used in the connection establishment request.
