  • Publication number: 20060253666
    Abstract: A memory circuit for use in a data processing circuit is described, in which memory cells have at least two states, each state being determined by both a first voltage level corresponding to a first supply line and a second voltage level corresponding to a second supply line. The memory circuit comprises a readable state in which information stored in a memory cell is readable and an unreadable state in which information stored in said memory cell is reliably retained but unreadable. Changing the first voltage level but keeping the second voltage level substantially constant effects a transition between the readable state and the unreadable state. In use, the static power consumption of the memory cell in the unreadable state is less than static power consumption of the memory cell in the readable state.

  • Publication number: 20060218287
    Abstract: The invention is directed to techniques for providing an event notification string over a network to a notification server. An application server includes a notifying application that monitors, or otherwise determines, the occurrence of an event of interest to a target user who uses a device that can receive notification of the event. The notifying application generates an event notification string that indicates that a notification to the target user should be made. The notifying application then sends the event notification string over a network, such as an IP (Internet Protocol) network, to a notification server, which provides an event notification application that processes the event notification string. The event notification application determines the identity of the target user, if the event notification string does not provide this information itself, and which devices accessed by the target user should receive the notification.

  • Publication number: 20060075067
    Abstract: In a multinode data processing system in which nodes exchange information over a network or through a switch, a structure and mechanism are provided which enables data packets to be sent and received in any order. Normally, if in-order transmission and receipt are required, then transmission over a single path is essential to insure proper reassembly. However, the present mechanism avoids this necessity and permits Remote Direct Memory Access (RDMA) operations to be carried out simultaneously over multiple paths. This provides a data striping mode of operation in which data transfers can be carried out much faster since packets of single or multiple RDMA messages can be portioned and transferred over several paths simultaneously, thus providing the ability to utilize the full system bandwidth that is available.

  • Publication number: 20060059242
    Abstract: A method is provided for operating a communications adapter employed in a multinode data processing system in a fashion which enhances the performance of remote direct memory access data transfers. The system is provided with pointers and a table which are employed to determine whether or not an address which has been supplied for the transfer has already been mapped to a real address at the source or destination node. The table is also preferably provided with counters which can be incremented or decremented to enable the use of least recently used mechanisms at the upper level protocol layers to more efficiently control the setting and resetting of table entries.

  • Publication number: 20060059282
    Abstract: In a multinode data processing system in which the nodes communicate with one another via communication adapters over a network or switch, the adapters are provided with a dual register mechanism for tracking microcode task status. Upon the issuance of a disruptive command that requires attention from one of the nodes, the task status maintained in one register is copied to the snapshot register. As tasks within the adapter are completed, both registers are updated, thus providing a mechanism for the nodes to determine that all tasks active at the time of the disruptive command have completed. This means that the nodes now have a mechanism for determining, as soon as possible, that all tasks that are active when a disruptive command occurs have completed, thus allowing the data processing node to perform such operations as releasing system memory that is associated with the disruptive command, thus eliminating temporal overhead that can affect performance.

  • Publication number: 20060045005
    Abstract: In remote direct memory access transfers in a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, failures in the nodes or in the communication adapters can produce the phenomenon known as trickle traffic, which is data that has been received from the switch or from the network that is stale but which may have all the signatures of a valid packet data. The present invention addresses the trickle traffic problem in two situations: node failure and adapter failure. In the node failure situation randomly generated keys are used to reestablish connections to the adapter while providing a mechanism for the recognition of stale packets. In the adapter failure situation, a round robin context allocation approach is used with adapter state contexts being provided with state information which helps to identify stale packets.

  • Publication number: 20060047771
    Abstract: In remote direct memory access (RDMA) transfers in a multinode data processing system in which the nodes communicate with one another through communication adapters coupled to a switch or network, there is a need for the system to ensure efficient memory protection mechanisms across jobs. A method is thus desired for addressing virtual memory on local and remote servers that is independent of the process ID on the local and/or remote node. The use of global Translation Control Entry (TCE) tables that are accessed/owned by RDMA jobs and are managed by a device driver in conjunction with a Protocol Virtual Offset (PVO) address format solves this problem.

  • Publication number: 20060045109
    Abstract: In a multinode data processing system in which data is transferred, via direct memory access (DMA) or in remote direct memory access (RDMA), from a source node to at least one destination node through communication adapters coupling each node to a network or switch, a method is provided in which interrupt handling is overlapped with data transfer so as to allow interrupt processing overhead to run in parallel at the destination node with the movement of data to provide performance benefits. The method is also applicable to situations involving multiple interrupt levels corresponding to multithreaded handling capabilities.

  • Publication number: 20060047767
    Abstract: A unified web-based voice messaging system uses an application server, configured for executing a voice application defined by XML documents, that accesses subscriber attributes from a standardized information database server (such as LDAP), and messages from a standardized messaging server (such as IMAP), regardless of message format. The application server, upon receiving a request from a browser serving a user, accesses the standardized database server to obtain attribute information for responding to the voice application operation request. The application server generates an HTML document having media content and control tags for personalized execution of the voice application operation based on the attribute information obtained from the standardized database server. The application server also is configured for storing messages for a called party in the standardized messaging server by storing within the message format information that specifies the corresponding message format.
