A Virtual Machine (VM) is created utilizing a virtual Operating System (OS) disk and virtual application disks, each of which may be from disparate third party suppliers. One or more files in the virtual application disk are then linked to a specific file system location (node) in the virtual OS disk.

Creating a virtual machine containing third party code

A request for a content document is sent by a client device to a content server through a first network connection. A current network characteristic of the first network connection differs from a configured download constraint to download a content portion of the content document. A root document that omits the content portion of the content document and that includes a content stub is downloaded from the content server. The content stub identifies the content portion using a content identifier and specifies the configured download constraint. A network connection change to the content server from the first network connection to a second network connection that satisfies the configured download constraint to download the content portion of the content document is detected, and the content portion is downloaded using the second network connection and the content identifier within the content stub.

Network-aware structured content downloads

Methods and systems for optimizing a build order of component source modules comprises creating a dependency graph based on dependency information. Historical build information associated with previous build failures is then used to calculate relative failure factors for paths of the dependency graph; and the relative failure factors are used to determine an order of traversal of the dependency graph during a build process in which component binary modules are built from the component source modules.

Using build history information to optimize a software build process

A request for content is received at a content server via a first network connection from a client device. The content includes a set of individual portions represented within a root document that are each configurable within the root document with syntactically assigned download constraints that specify network characteristics under which the portions of the content are downloadable. A determination to defer at least one portion of the content for download is made based upon a network characteristic of the first network connection not satisfying a configured download constraint syntactically assigned within the root document to the at least one portion of the content. The root document is sent with each deferred portion replaced with a content stub that each syntactically identifies the respective deferred portion of the content as a deferred content portion and includes a deferred content portion identifier of the respective deferred portion of the content.

A request for content is sent, using a client device, to a content server through a first network connection. A root document is received from the content server. The root document includes at least one content stub, where each content stub identifies a respective portion of the content as a deferred portion of the content and includes a content identifier of the respective deferred portion of the content. A network connection change to the content server from the first network connection to a second network connection is detected. A determination is made to download at least one deferred portion of the content through the second network connection based upon a configured download constraint assigned to the deferred portion of the content and a network characteristic of the second network connection. The deferred portion of the content identified by the respective content stub is obtained.

Under the present invention, the performance of a set of system resources is monitored in response to incoming request traffic. When a system resource is approaching an overload condition, a corrective action is identified and implemented. Overload thresholds for each system resource and appropriate corrective actions are contained within a management policy. Based on a performance history of the corrective actions, the management policy can be changed/revised.

A first and second data handling systems provides for shared resources in a docked mobile environment. The first data handling system maintains a set of execution tasks within the first data handling system having a system dock interface to physically couple to the second data handling system. The first data handling system assigns a task to be executed by the second data handling system while the two systems are physically coupled.

Shared resources in a docked mobile environment

Sharing resources in a docked mobile environment comprises maintaining a set of execution tasks within a first data handling system having a system dock interface to physically couple to a second data handling system and assigning a task to be executed by the second data handling system while the two systems are physically coupled. The described method further comprises detecting a physical decoupling of the first and second data handling systems and displaying an execution result of the task via a first display element of the first data handling system in response to such a detection.

Embodiments of the present invention address deficiencies of the art in respect to configuring a computing appliance and provide a method, system and computer program product for device certificate based virtual appliance configuration. In one embodiment of the invention, a virtual appliance secure configuration method can be provided. The method can include mounting non-volatile storage to the virtual appliance, retrieving a device certificate from the mounted storage and extracting a signature from the device certificate, activating the virtual appliance in a network domain and acquiring an adapter address and unique identifier for the virtual appliance, and authenticating the signature with the adapter address and unique identifier to ensure a unique active instance of the virtual appliance.

A request for content is received at a content server via a first network connection from a client device. The content includes a set of portions represented within a root document that are each configurable with assigned download constraints that specify network characteristics under which the individual portions of the content are downloadable. A determination to defer at least one portion of the content for download is made based upon a network characteristic of the first network connection not satisfying a configured download constraint assigned to the at least one portion of the content. The root document is sent with each deferred portion of the content replaced with a content stub within the root document. Each content stub identifies the respective deferred portion of the content as a deferred content portion and includes a deferred content portion identifier of the respective deferred portion of the content.

Embodiments of the present invention include a method for resource optimization of map/reduce computing in a computing cluster. The method can include receiving a computational problem for processing in a map/reduce module, subdividing the computational problem into a set of sub-problems and mapping a selection of the sub-problems in the set to respective nodes in a computing cluster, for example a cloud computing cluster, computing for a subset of the nodes in the computing cluster a required resource capacity of the subset of the nodes to process a mapped one of the sub-problems and an existing capacity of the subset of the nodes, and augmenting the existing capacity to an augmented capacity when the required resource capacity exceeds the existing capacity, and when a cost of augmenting the existing capacity to the augmented capacity does not exceed a penalty for breaching a service level agreement (SLA) for the subset of the nodes.

A computing device associated with a cloud computing environment identifies a first worker cloud computing device from a group of worker cloud computing devices with available resources sufficient to meet required resources for a highest-priority task associated with a computing job including a group of prioritized tasks. A determination is made as to whether an ownership conflict would result from an assignment of the highest-priority task to the first worker cloud computing device based upon ownership information associated with the computing job and ownership information associated with at least one other task assigned to the first worker cloud computing device. The highest-priority task is assigned to the first worker cloud computing device in response to determining that the ownership conflict would not result from the assignment of the highest-priority task to the first worker cloud computing device.
