摘要： A method, computer program product, and data processing system for sharing memory protection tables and address translation tables among multiple Host Channel Adapters are disclosed. The protection and address translation tables for a shared memory region are written in memory of the host. The Host Channel Adapters are registered with the memory region so that each adapter stores an address pointer to the tables. In this way, the tables need not be duplicated for each adapter.

摘要： A method, program and system for associating memory windows with memory regions in an infiniband data storage system are provided. The invention comprises registering a Memory Region, wherein the Memory Region is a set of virtually contiguous memory addresses defined by a virtual address and length. The system then establishes and maintains a Window Reference Count (WRC) for the Memory Region, which tracks the number of Memory Windows which are bound to the Memory Region. When the system binds a Memory Window to the Memory Region, the value of the WRC is incremented. When a Memory Window is unbound from the Memory Region, the value of the WRC is decremented. If no Memory Windows are bound to the Memory Region, the value of the WRC is zero. The Memory Region is not deregistered unless the value of the WRC equals zero.
摘要翻译：提供了一种用于将存储器窗口与无限数据存储系统中的存储器区域相关联的方法，程序和系统。本发明包括登记存储器区域，其中存储器区域是由虚拟地址和长度定义的一组虚拟连续的存储器地址。然后，系统建立并维护用于内存区域的窗口引用计数（WRC），该区域跟踪绑定到内存区域的内存窗口的数量。当系统将内存窗口绑定到内存区域时，WRC的值将增加。当存储器窗口从存储器区域中取消绑定时，WRC的值递减。如果没有内存Windows绑定到内存区域，则WRC的值为零。除非WRC的值等于零，否则内存区域不会被注销。

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.
摘要翻译：提供了一种使用通信管理协议的私有数据字段建立多个连接的系统和方法。利用本发明，服务ID标识特定消费者，并且专用数据字段包含要建立的每个连接的连接属性的列表。主动端请求连接，被动方回复连接请求。主动端将被动方发送连接建立请求。该连接建立请求包括识别与服务相关联的被动侧进程的服务ID。该连接建立请求还包括与服务ID相关联的一个或多个连接的服务和数据报服务的通信属性。被动将连接请求传递给与服务关联的进程。如果被动侧进程不希望执行该服务，则将一个否定的回复消息返回到主动端。如果被动侧进程确实希望执行该服务，则肯定的答复返回到主动侧，并且回复包括用于连接的通信属性和与在连接建立请求中使用的服务ID相关联的不可靠服务。

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： An apparatus and method for implementing multicast in system area network channel adapters are provided. With the apparatus and method, a multicast packet is received in a channel adapter of an end node. The channel adapter determines which local queue pairs are party of the multicast group identified by a destination local identifier in the multicast data packet. Based on this determination, the channel adapter replicates the data packet and delivers a copy of the data packet to each local queue pair that is part of the multicast group.

摘要： A method and system are provided for dynamically informing an operating system (OS) of a distributed computer system, when a (new) device is added on the network. An OS registers with the subnet administrator (SA) to be notified when a new component is added to the subnet and placed in a partition to which the OS has access. The subnet manager (SM) initializes and configures the new component that is added and, through the partition manager, associates the component to one or more partitions of the subnet. The SA then notifies the OSs with access to the partition(s) to which the component is associated and that have a right to access the new component that the new component is available to the OS. Following, the OS updates a database of available components to include the new component and establishes communication with the new component.

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, apparatus, and computer implemented instructions for managing a plurality of caches of data, wherein the data processing system includes a plurality of independent computers. In response to initiating a read operation to read data on a data block, an indication is posted on a directory of data blocks identifying the computer that now holds a copy of that block and a location in the memory of that computer where a flag associated with that block is held. Then in response to initiating a write operation on that data block, messages are sent to all the computers holding that block which resets the said flag, thus informing each computer that the data in that block is no longer valid. These messages are sent using means that perform that flag reset without, in the preferred embodiment, any overhead of interruption of processing on the computers where the flags reside.

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.
