  • Patent number: 7835359
    Abstract: A method, an apparatus and a recording medium are provided for communicating message payload data, especially noncontiguous message data, from a first node of a network to a second node of the network in response to a request to transmit a message. Such method includes dividing the length of a data payload to be transmitted into a plurality of submessage payload lengths, i.e., into at least a first submessage payload length and a second submessage payload length. Then, a first ordered submessage is transmitted from the first node for delivery to the second node, the first ordered submessage having the first submessage payload length. A first state of an environment is then determined in the first node as if the step of transmitting the first ordered submessage were already completed.

  • Patent number: 7302607
    Abstract: A method for recovery in a two-node data processing system is provided wherein each node is a primary server for a first nonvolatile storage device and for which there is provided shared access to a second nonvolatile storage device for which the other node is a primary server and wherein each node also includes a direct connection to the shared nonvolatile storage device for which the other node is the primary server. Upon notification of failure, the method operates by first confirming continued access by each node to the nonvolatile storage device for which it is the primary server and then by attempting to access the shared nonvolatile storage device via the direct connection and by waiting for a time sufficient for the same process to be carried out by the other node. If access to the shared nonvolatile storage device is successful, the node takes control of both nonvolatile storage devices. If the access is not successful a comparison of node numbers is carried out to decide the issue of control.

  • Patent number: 7187688
    Abstract: A method is provided for selecting a data source for transmission on one of several logical (virtual) lanes embodied in a single physical connection. Lanes are assigned to either a high priority class or to a low priority class. One of six conditions is employed to determine when re-arbitration of lane priorities is desired. When this occurs a next source for transmission is selected based on a the specification of the maximum number of high priority packets that can be sent after a lower priority transmission has been interrupted. Alternatively, a next source for transmission is selected based on a the specification of the maximum number of high priority packets that can be sent while a lower priority packet is waiting. If initialized correctly, the arbiter keeps all of the packets of a high priority packet contiguous, while allowing lower priority packets to be interrupted by the higher priority packets, but not to the point of starvation of the lower priority packets.

  • Patent number: 6978016
    Abstract: The modular exponentiation function used in public key encryption and decryption systems is implemented in a standalone engine having at its core modular multiplication circuits which operate in two phases which share overlapping hardware structures. The partitioning of large arrays in the hardware structure, for multiplication and addition, into smaller structures results in a multiplier design which includes a series of nearly identical processing elements linked together in a chained fashion. As a result of the two-phase operation and the chaining together of partitioned processing elements, the overall structure is operable in a pipelined fashion to improve throughput and speed. The chained processing elements are constructed so as to provide a partitionable chain with separate parts for processing factors of the modulus. In this mode, the system is particularly useful for exploiting characteristics of the Chinese Remainder Theorem to perform rapid exponentiation operations.

  • Patent number: 6957243
    Abstract: Finite field elements from the Galois field GF(2k) are represented as polynomials with binary valued coefficients. As such, multiplication in the field is defined modulo an irreducible polynomial of degree k?1. One of the multiplicands is treated in blocks of polynomials of degree n?1 so that the multiplier operates over T cycles where k=nT. If k is not a composite number to start with, higher order terms are added, so that multipliers are now constructable even when k is prime. Since n<k, the construction of the needed multiplier circuits are much simpler. Designers are now provided with an opportunity of easily trading off circuit speed for circuit complexity in an orderly and structured fashion.

  • Patent number: 6934950
    Abstract: Method, computer program product, and apparatus for efficiently dispatching threads in a multi-threaded communication library which become runnable by completion of an event. Each thread has a thread-specific structure containing a “ready flag” and a POSIX thread condition variable unique to that thread. Each message is assigned a “handle”. When a thread waits for a message, thread-specific structure is attached to the message handle being waited on, and the thread is enqueued, waiting for its condition variable to be signaled. When a message completes, the message matching logic sets the ready flag to READY, and causes the queue to be examined. The queue manager scans the queue of waiting threads, and sends a thread awakening condition signal to one of the threads with its ready flag set to READY. The queue manager can implement any desired policy, including First-In-First-Out (FIFO), Last-In-First-Out (LIFO), or some other thread priority scheduling policy.

  • Patent number: 6910080
    Abstract: In a multinode data processing system, the messages to be transmitted from node to node, per the request of an application program, are stored in a queue on one of the nodes. Acknowledgment of the receipt of the messages is used to control transmission of messages at future times by adjusting the maximum number of allowable messages to be sent from the queue and also by adjusting the time interval that the system waits before retransmitting unacknowledged messages. This permits the use of so-called “unreliable” messaging protocols and relieves application programs and programmers from the burden of employing more complicated protocols.

  • Patent number: 6910183
    Abstract: The present invention provides facilities for tagging files or data with attribute information in the form of a file tag (TAGINFO) which contains an identifier for text information (TEXTFLAG) and an attribute (COSID) for identifying encoding schemes. TXTFLAG is an auto conversion flag. Furthermore, a runtime attribute (process CCSLD) is assigned to a process specifying the runtime encoding scheme. A conversion is done automatically by an auto conversion function if both CCSIDs allow a conversion. Files having no file tag are tagged with a virtual file tag by means of an automatic tagging (AUTOTAG) function using heuristic rules for determining whether the data or file contains text or binary information. Old applications must work with untagged files as before. Existing applications should be able to benefit from auto conversion and thereby to be enabled to process new, tagged files without code changes.
