    摘要： A guaranteed distributed failure notification method is described, wherein a failure notification (FN) facility allows applications using the facility to create FN groups to which the application associates an application state. The application registers failure handlers with the FN facility on nodes in the FN group; each failure handler is associated with a specific FN group. When, on a given node, the FN facility learns of a failure in the FN group, the facility executes the associated failure handler on that node. System failures detected by the application are signaled to other FN group members using the facility. The facility detects system failures that occur in an overlay network on which the facility is implemented, and signals a failure notification to the other FN group members.

    摘要： A method for multicasting a message in a computer network is described, in which at least some nodes of a multicast group transmit fault recovery information to other nodes of the group in addition to, or as part of, the message itself. The fault recovery information allows nodes to determine what dissemination responsibility should be assigned to successor nodes in the event that one or more nodes of the multicast group fail.

    摘要： An application programming interface (API) may receive high level file commands and implement those commands using the storage mechanism on a smart card. The smart card may have a processor and storage mechanism and may communicate to a host device using a packet based communication protocol, such as ADPU. The API may translate the high level file commands into one or more ADPU commands, communicate with the smart card, receive APDU responses, and translate the responses into high level file commands. A high level file command may allow access to a file using long file names, a hierarchical directory structure, and may allow creating, writing, reading, and deleting a file. Some embodiments may have more complex functions for navigating and manipulating a hierarchical directory structure, as well as defining metadata including access privileges and file types to individual files.

    摘要： The present invention provides providing predictable scheduling of programs using repeating precomputed schedules on discretely scheduled and/or multiprocessor operating systems. In one embodiment, a scheduler accesses an activity scheduling graph. The activity scheduling graph is comprised of nodes each representing a recurring execution interval, and has one root, one or more leaves, and at least one path from the root to each leaf. Each node is on at least one path from the root to a leaf, and the number of times the execution interval represented by each node occurs during the traversal of the graph is equal to the number of paths from the root to a leaf that the node is on. Each node has associated with it an execution interval length, and is adapted to being dedicated to executing the threads of a single activity. There may be one scheduling graph for each processor, or a scheduling graph may traverse multiple processors. Start and end times for reservations and constraints are adjusted to compensate for the granularity of the clock of the system. Furthermore, the scheduler may use an existing priority-based scheduler in order to cause scheduling decisions it has made to be acted upon.
