Abstract: Embodiments of the invention relate to scanning, by a first processor in a work group, a memory associated with the first processor for data. The first processor updates a first data structure to include at least a portion of the data based on the scanning. The first processor transmits a representation of the first data structure to one or more peer processors of the first processor included in the work group using a dedicated link. The first processor receives a representation of a second data structure associated with at least one of the one or more peer processors of the first processor. The first processor updates the first data structure based on the received representation of the second data structure.

Abstract: A method to redirect SRB routines from otherwise non-zIIP eligible processes on an IBM z/OS series mainframe to a zIIP eligible enclave is disclosed. This redirection is achieved by intercepting otherwise blocked operations and allowing them to complete processing without errors imposed by the zIIP processor configuration. After appropriately intercepting and redirecting these blocked operations more processing may be performed on the more financially cost effective zIIP processor by users of mainframe computing environments.

Abstract: Aspects of the present invention provide a method of specifying a device driver design for a board device. The method includes receiving a board device with various functional elements and on-board storage to be operatively coupled to a computing device through an interconnect. The device driver design is specified through the identification of one or more device driver parameters. The device driver parameters are to be used subsequently to customize an adaptive device driver that interfaces with the board device and each of the one or more functional elements. Device driver parameters are stored in a predetermined storage construct allocated from the board device. These device driver parameters remain stored in the storage construct until there is a need for the board device and corresponding device driver. Customizing the adaptive device driver is done after the device driver parameters have been stored and typically when a computer device starts or ‘boots”.

Abstract: A method and apparatus for processing data by a computer and a method of determining data storage requirements of a computer for earning out a data processing task.

Abstract: This method includes steps for the parallel management of a first list and of a second list. The first list corresponds to a list of tasks to be carried out. The second list corresponds to a list of variables indicating the presence or absence of tasks to be carried out. The list of tasks is managed in a “FIFO” manner, that is to say that the first task inputted into the list is the first task to be executed. A task interruption is managed using a “Test And Set” function executed on the elements of the second list, the “Test And Set” function being a function which cannot be interrupted and including the following steps: reading the value of the element in question, storing the read value in a local memory, and assigning a predetermined value to the element which has just been read.

Abstract: Techniques are disclosed for a management application running on a virtualization management platform and a module on a virtual machine host to communicate via an opaque pass-through channel for transporting data through the management platform and intermediate layer(s) of the virtual machine host between the management application and the module. In one embodiment, the data is identified by a key which is unique across management applications and includes a namespace registered by the management application on the management platform and registered by the module on the virtual machine host. In another embodiment, the namespace may indicate an association of the data with one or more entities such as a distributed virtual switch, port groups, ports, and virtual machine hosts. Configuration property settings for an entity may be propagated to its sub-entities based on inheritance. Further, the data may be persisted in database(s) of the management platform and/or the intermediate layer(s).

Abstract: The use of linear programming may enable the achievement of real-time task execution prioritization. A linear model may be constructed based at least on a set of computing tasks, a linearly expressible goal for the set of computing tasks, one or more linear resource constraints, and one or more computing task dependencies. The linear model is then used to calculate a shadow price for each of a plurality of resource time prediction constraints, in which each shadow price may represent a priority value for a corresponding computing task. When a computing resource becomes available, a computing task with a highest priority value that is able to use the computing resource may be executed.

Abstract: Methods and systems for reducing communication during video processing utilizing merge buffering are disclosed and may include storing data in a merge buffer in the virtual machine layer in a wireless communication device comprising a virtual machine user layer, a native user layer, a kernel, and a video processor. The data may then be communicated to the kernel via the native user layer. The data may include function calls, and/or kernel remote procedure calls. The data may be communicated via an application programming interface. Video data may be processed in the video processor based on the communicated data. The virtual machine user layer may include a Java environment. The data may be communicated to the kernel via the native user layer when the merge buffer is full or filled to a predetermined level.

Abstract: One embodiment of the present invention enables threads executing on a processor to locally generate and execute work within that processor by way of work queues and command blocks. A device driver, as an initialization procedure for establishing memory objects that enable the threads to locally generate and execute work, generates a work queue, and sets a GP_GET pointer of the work queue to the first entry in the work queue. The device driver also, during the initialization procedure, sets a GP_PUT pointer of the work queue to the last free entry included in the work queue, thereby establishing a range of entries in the work queue into which new work generated by the threads can be loaded and subsequently executed by the processor. The threads then populate command blocks with generated work and point entries in the work queue to the command blocks to effect processor execution of the work stored in the command blocks.

Abstract: Processing of tickets received by a ticket processing system is performed by allowing processes running on one or more hosts to access a ticket processing table to retrieve and process the tickets. A weighted load distributor (WLD) grants weighted round robin turn access to the processes running on the hosts. The WLDs running on different hosts coordinate so that a primary WLD is selected that is responsible for distributing turn access to the ticket processing table to various requesting processes. The hosts use a throttle to determine the real-time availability of resources for the hosts. The throttle determines whether a process should be allowed to proceed with processing tasks associated with a particular ticket based on resource costs associated with the required processing, as well as resources available to the respective host and ticket priority.

Abstract: A data connection of a shared resource is placed in isolation mode to remove its ability to communicate with other data connections of the shared resource. This ability to isolate the data connection is dynamic in that it can be turned on/off at any time. This provides increased data security for the entities using the data connection.

Abstract: A computer-implemented method for recovering an application is described. A priority level is assigned to a process that interacts with the application. A state of the application is monitored. A determination is made that the state of the application is unstable. A first process that is assigned a first priority level is disabled. A determination is made as to whether the state of the application remains unstable.
