  • Memory management for closures
    Patent number: 8341614
    Abstract: Methods, software media, compilers and programming techniques are described for creating copyable stack-based closures, such as a block, for languages which allocate automatic or local variables on a stack memory structure. In one exemplary method, a data structure of the block is first written to the stack memory structure, and this may be the automatic default operation, at run-time, for the block; then, a block copy instruction, added explicitly (in one embodiment) by a programmer during creation of the block, is executed to copy the block to a heap memory structure. The block includes a function pointer that references a function which uses data in the block.

  • Flow sampling with top talkers
    Patent number: 8335160
    Abstract: An improved network flow sampling apparatus and corresponding method more intelligently selects flows to be reported beyond random flow or packet sampling intervals. Evaluation of flows selects top talkers or heavy hitters as important flows that most impact traffic and therefore should be reported. Top talkers are flows defined based on a customized definition according to, for example, number of packets in a flow, number of bytes in a flow, or bandwidth consumed by a flow. An external collector can thus proceed with traffic profiling or other flow monitoring purposes with a more intelligently determined network flow sample.

  • Method and system for generating a hierarchical tree representing stack traces
    Patent number: 8336033
    Abstract: A system and method are provided to generate a hierarchical tree representing stack traces. In one embodiment, stack trace elements in a plurality of stack traces relating to profiling of an application executing at a first virtual machine are identified, the stack trace elements relating to profiling events being detected during the profiling of the application. The identified stack trace elements are sorted as one of parent elements; parent/child elements, or child elements based on a number of times a stack trace element has appeared in the plurality of stack traces and its relationship with other elements in the plurality of stack traces. A tree having nodes to represent the stack trace elements is created such that that the child elements branch from the parent/child elements or the parent elements, and the parent/child elements branch from the parent elements.

  • Laminar bell water display
    Patent number: 8333331
    Abstract: A decorative water display provides a laminar water bell. A gas burner may be provided inside the laminar water bell to produce a decorative flame. A laminar nozzle having an outlet arranged to eject a laminar jet of water upwardly in a substantially vertical direction may strike an impactor suspended directly above the outlet of the laminar nozzle such that the laminar jet of water forms the laminar water bell. Alternatively, a vertical pipe may supply water to a thin annular region between two plates such that water flowing between the two plates assumes a generally laminar flow characteristic and forms the laminar water bell when ejected from between the two plates. Alternatively, a hemispherical nozzle may have a slot arranged to eject a sheet of water upwardly to form a segment of the laminar water bell.

  • Dynamic VM cloning on request from application based on mapping of virtual hardware configuration to the identified physical hardware resources
    Patent number: 8336046
    Abstract: Methods and apparatuses enable creation of a virtual machine (VM) clone initiated through application or service logic. The application requests generation of a VM clone from within the runtime execution of the application. The request is serviced by a VM generator, which identifies a state of the VM to clone and identifies hardware resources on which to create the VM clone. Based on a determination of what resources on which to generate the VM clone, the VM generator creates the VM clone on the determined resources, having the identified state. In one embodiment, a use case of resource copy or reference copy is selected for each resource. In one embodiment, the VM generator considers a number of factors in determining where to instantiate the VM clone. The parameters may include hints or preference parameters sent by the application and/or resource loading or performance.
