  • Publication number: 20190068506
    Abstract: A resource management system for a virtual machine computing environment includes a software component that optimizes capacity between server clusters or groups by monitoring the capacity of server clusters or groups and automatically adding and removing host systems to and from server clusters or groups. The software component may be implemented at a server cluster management level to monitor and execute host system moves between server clusters and/or at a higher level in the resource management hierarchy. At the higher level, the software component is configured to monitor and execute host system moves between sets of server clusters being managed by different server cluster management agents.

  • Publication number: 20190043052
    Abstract: A method, system, apparatus, and computer program for conducting a real-time payment transaction. The method includes receiving a request for payment from a creditor financial institution (FI), and forwarding it to a debtor (FI). A payment transaction message is received from the debtor financial institution, specifying an amount of payment requested in the request, and is forwarded to the creditor FI such that the amount of payment is credited to an account in real-time. The debtor FI can request a return of the payment, in which case the creditor FI can comply therewith or refuse the return the payment. Also, an unsettled financial position of the debtor FI can be settled where that position does not exceed a combination of a pre-funded balance in a settlement account and a net debit cap value, and multiple settlements can be performed depending on a relationship between the position and combination.

  • Patent number: 10157089
    Abstract: An event management structure for an embedded system, which supports multiple waiters waiting on the same event without replicating the events for each waiter, is provided. Notifications of events are received from entities within an embedded system. The event management architecture then posts the events to a central queue and generates a unique identification tag for each posted event. Additionally, entities within the embedded system are allowed to wait on specific events. More specifically, entities may request access to specific events based on the unique identification tag associated with a particular event. In further implementations, data associated with queued events may be provided to the waiters. In some implementations, events matching a specific description since a particular event, identified by its unique identification tag, may be requested by entities in the embedded system.

  • Patent number: 10025602
    Abstract: This application discloses a computing system configured to perform a pre-linked embedding process during build-time of a root-kernel application. The computing system can pre-link one or more dynamically-linkable executable modules against exported symbols of a root-kernel image, and embed the pre-linked executable modules into the root-kernel image. The computing system can load the root-kernel image having the embedded pre-linked executable modules into a memory of an embedded system, wherein at least one processing device in the embedded system is configured to execute the embedded pre-linked executable modules directly from the memory.

  • Publication number: 20170221066
    Abstract: A method, system, apparatus, and computer program for conducting a real-time payment settlement transaction. The method includes determining a prefunded requirement for one or more financial institutions. A prefunded balance is stored, based on a prefunded payment received in a separate funding account, for each of the one or more financial institutions. The method further includes receiving an electronic request for payment message from at least one creditor financial institution, and forwarding the electronic request for payment message to at least one debtor financial institution, the electronic request for payment message requesting that a payment be made to the at least one creditor financial institution and comparing the amount of payment requested in an electronic payment transaction to the prefunded balance of the at least one debtor financial institution. A real-time financial settlement transaction is performed based on a result of the comparing step.

  • Patent number: 9696818
    Abstract: Techniques for bidirectional text selection are disclosed. When a character selection is received, such as a “Shift+Arrow” input, the unanchored side of a selection area is adjusted by one glyph in the selection direction. The adjusted selection area is then evaluated in terms of logical indices that define the selection. If the range of logical indices is contiguous, such as the range {3, 4, 5}, then the adjusted selection area is accepted, although further adjustments are optionally made for glyphs that map to multiple characters. However, if the range of logical indices is noncontiguous, such as {3, 4, 6}, then the selection area is further adjusted until a contiguous selection of logical indices is achieved. For instance, a character corresponding to logical index {5} is added to a selection of characters corresponding to logical indices {3, 4, 6} to produce a selection that is logically and visually contiguous.

  • Patent number: 9678782
    Abstract: Embodiments associate software applications with computing resource containers based on a placement rule and a selected failure correlation. A placement rule indicates that a first software application is to be co-located with a second software application during execution of the first and second software applications. The placement rule also indicates that the first software application is to be separated from the second software application during execution of the first and second software applications. Failure correlations are determined for a plurality of computing resources associated with the first software application. A computing resource with a lowest failure correlation is selected from the plurality of computing resources, and the second software application is associated with the selected computing resource despite the association violating the placement rule.

  • Patent number: 9571406
    Abstract: Embodiments determine communication delay along a network path between a source and a destination in a network. A target injection rate is calculated based on the determined delay and a predetermined maximum queuing delay threshold. Data packets are transmitted along the network path using an inter-packet delay that is based on the target injection rate.

  • Patent number: 9563453
    Abstract: One or more embodiments of the present invention provide a technique for effectively managing virtualized computing systems with an unlimited number of hardware resources. Host systems included in a virtualized computer system are organized into a scalable, peer-to-peer (P2P) network in which host systems arrange themselves into a network overlay to communicate with one another. The network overlay enables the host systems to perform a variety of operations, which include dividing computing resources of the host systems among a plurality of virtual machines (VMs), load balancing VMs across the host systems, and performing an initial placement of a VM in one of the host systems.

  • Publication number: 20160357674
    Abstract: A cache in a computer system is configured with a plurality of monitoring slices, each comprising a separately addressable partition of the cache. With each monitoring slice is associated a respective sub-range of a hash function, which has a range that includes at least the addressable partitions of the cache that comprise the monitoring slices. For each of a stream of location identifiers submitted by at least one entity, a respective location identifier hash value is computed and used to determine in which, if any, monitoring slice-associated hash function sub-range the location identifier hash value falls. For at least one of the monitoring slices, a frequency value is determined as a function of how many of the location identifier hash values fell into the slice's associated hash function sub-range, and a respective cache utility value is then computed as a function of each monitoring slice's frequency value.
