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： 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 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 mechanism for allowing a single physical IB node to virtualize a plurality of host channel adapters is provided. This includes providing the appearance of both a router and multiple virtual HCA's residing behind that router, to the external REAL subnet components. Each virtual host channel adapter will have unique access control levels. One or more InfiniBand subnets are virtualized in such a way that nodes residing both within the virtual subnets and in separate physical subnets are completely unaware of the virtualization. This virtualization of InfiniBand subnets significantly increases the horizontal scaling capabilities of a single InfiniBand physical component, while at the same time provides “native” network throughput for all the virtual hosts.

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.

摘要： A method for determining parameters needed to communicate with a remote node in a computer network is provided. The invention comprises determining the location of the remote node to which an InfiniBand (IB) node might desire to communicate. This resolution comprises determining the location of the remote node based on a desired application or service, and then determining the IB parameters needed to communicate with the remote node. The resolution might also involve determining the specific queue pairs that associated with the service dynamically. The general solution is applied to IP service resolution.

摘要： An apparatus and method for distributed intersystem lock optimization are provided. With the apparatus and method of the present invention, the time required to obtain an uncontested lock, meaning a lock that no other program or process in the distributed system is simultaneously attempting to acquire, is minimized. The apparatus and method of the present invention increases the speed with which locks are acquired by splitting the process of obtaining a lock into two separate operations: a test for contention, and then if contention exists, a full lock operation. The test for contention is made fast by associating each lock with a memory location, and using an atomic operation or the like, to atomically set the memory location associated with the lock to a different value. If the lock is found to be contested, meaning that another program or process has already locked it, control is turned over to a slower operation than ensures that the lock-requesting program or process will eventually be granted the lock.
摘要翻译：提供了一种用于分布式系统间锁优化的装置和方法。利用本发明的装置和方法，获得无争议锁所需的时间意味着分布式系统中没有其他程序或进程同时尝试获取的锁定被最小化。本发明的装置和方法通过将获得锁的处理分成两个单独的操作来增加锁获取的速度：竞争测试，然后如果存在争用，则提供完全锁定操作。通过将每个锁与存储器位置相关联，并且使用原子操作等来将与锁相关联的存储器位置原子地设置为不同的值来快速进行争用测试。如果锁被发现有争议，意味着另一个程序或进程已经锁定它，则将控制权转换为较慢的操作，而不是确保最终将锁授权程序或进程锁定。

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 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 routing System Area Network (SAN) packets to multiple partitions within a single end node is provided. A range of Local Identification addresses (LIDs) are assigned to a channel adapter port within the SAN. Lower order bits within the LID are then assigned to select the particular partition in the end node. The Local ID Mask Control (LMC) field is used to assign multiple LIDs to a single port, using those low order bits to then route the message to the appropriate partition in the end node.
