Abstract: Some examples relate to firmware updates. In an example, a first core system determines firmware updates to be installed on the first core system and auxiliary systems of a data center. The first core system sends firmware update package generation instructions to a cloud infrastructure comprising data center firmware updates. The first core system downloads a firmware update package from the cloud infrastructure. The first core system updates firmware of the first core system, based on one or more firmware updates in the firmware update package. The first core system receives a request for a specific firmware update from an auxiliary system. Based on the request received from the auxiliary system, the first core system identifies the specific firmware update for the auxiliary system from the firmware update package. The first core system provides the specific firmware update to the auxiliary system.

Abstract: A system for fault tolerant batch processing in a virtual environment is configured to perform batch job execution, the system includes computing devices configured as a virtualized grid cluster by means of a virtualization platform, the cluster includes a centralized storage repository, a grid manager deployed on an instantiated virtual machine and a message bus whereby data and messages are exchanged between the grid manager and one or more grid nodes. The grid manager is configured to manage one or more incoming job requests, queue one or more of the received job requests in a job execution queue and monitor one or more virtual grid nodes.

Abstract: Cloud-based testing of applications allows an application under test (AUT) to be subjected to test loads mimicking expected high volume real-time production loads. Test loads can be applied from geographically distributed test load sources. During testing, the system can monitor usage of AUTs and the underlying cloud infrastructure (virtual machines, test servers, etc.) on which the AUT is executing. An AUT can be scaled, for instance, additional instances of the application can be started, and additional virtual machines can be configured and test servers provisioned if AUT or infrastructure usage exceeds specified thresholds during testing. A testing services provider can supply a web-based unified management console from which admins and test users can manage AUT testing.

Abstract: Methods and systems for monitoring and controlling a service level agreement are disclosed. A disclosed embodiment comprises a cloud platform hosting at least one application associated with at least one service level agreement, a monitoring module for collecting at least one metric relating to an application hosted on the cloud platform and terms of a service level agreement associated with each of the one or more metrics, and monitoring the metric collected against a service level objective in the service level agreement. The system may additionally comprise a controlling module for mapping a service level objective to a predefined operation rule, identifying one or more actions to be taken in accordance with the rule, assigning a priority to the one or more actions identified in accordance with the rule; and performing the one or more actions in accordance with the assigned priority of each of the one or more actions.

Abstract: Systems and methods for deriving a service level agreement for an application hosted on a cloud platform are defined. In accordance with at least one embodiment, deriving the service level agreement comprises packaging the application for deployment on a cloud platform, executing the packaged application in a sandboxed environment and capturing one or more application performance characteristics thereby, executing the packaged application in a sandboxed virtualized platform and further capturing one or more application performance characteristics thereby, mapping the one or more captured application performance characteristics to one or more service level objectives, and deriving a service level agreement on the basis of the one or more service level objectives, wherein the service level agreement comprises at least one of the one or more service level objectives.

Abstract: A method controls display of an image by dividing a source image into a plurality of M×N blocks of pixels, selecting a first one of the blocks, and transferring the pixels in the first block from a source memory to a display memory, the pixels in the first block transferred based on orientation change information. The selecting and transferring steps are then repeated to transfer pixels in remaining ones of the blocks to the display memory. Each block corresponds to only a portion of the source image, where any given portion represents less than a full line of pixels in the source image.

Abstract: A method for controlling display of an image includes generating a list of non-sequential random numbers, each number corresponding to a respective one of a plurality of lines in a source image. The lines in the source image are then transferred in non-sequential order from a first memory to a second memory based on the random numbers in the list and orientation change information. The resulting image in the second memory is then displayed in the desired orientation.

Abstract: A method for displaying an image in a display device initially includes storing a plurality masks in a memory. A mask of the plurality of masks is selected randomly from the plurality of masks, when control information is received for a source image and used to change the orientation of the source image. Each mask controls the transfer of image lines in a different non-sequential order based on the control information.
