Abstract: To enable continuous execution of an application, a system and method for transferring an application state is provided. A gesture corresponding to a transfer act is detected by a gesture detection module in a first device executing the application. The first device communicates with a registration and relay server to determine eligible transfer recipients based on criteria such as location and/or devices that are currently executing the application.

The application state DTOs are transferred via the server to the recipient device which enacts the application state DTOs to continue the execution of the application on the recipient device. Because the application state DTOs are platform independent, the application state can be transferred to almost any device that is able to execute the application.

The input/output adapter is also configured to decrement the reference count value by a corresponding reference count decrement value upon receiving an indication from an engine.

Abstract: A description of a resource associated with a service of an entity can be captured. The service can be associated with one or more resources, a constraint, and a demand. The resource can be associated with one or more characteristics including a utility, a limited availability, and a consumption rate. The entity can be an organization or a system.

The optimization problem can be solved optimally or approximately to establish a favorable allocation. The favorable allocation can minimizes the reconfiguration cost of the reconfiguring. The baseline scenario can be a normal operation of the service.

Abstract: Techniques are described for allocating computing resources to a task from a shared hardware structure. The techniques may involve receiving a request to execute a task for a tenant on shared hardware resources, and determining a set of computing resources for allocation to the task based on a service level agreement associated with the tenant. The set of computing resources can be allocated to the task based on the service level agreement associated with the tenant. In some aspects, one or more performance counters associated with one or more of the computing resources can be monitored to determine an activity level for the one or more computing resources during execution of the task, and one or more allocations of the computing resources for execution of the task can be adjusted based on the activity level for the one or more computing resources.

Abstract: User intentions can be derived from observations of user actions or they can be programmatically specified by an application or component that is performing an action. The intentions can then be utilized to adjust the operation of resource managers to better suit the actions being performed by the user or application, especially if such actions are not “typical”. Resource managers can inform a centralized intention manager of environmental constraints, including constraints on the resources they manage and constraints on their operation, such as various, pre-programmed independent modes of operation optimized for differencing circumstances. The intention manager can then instruct the resource managers in accordance with these environmental constraints when the intention manager is made aware of the intentions. If no further optimization can be achieved, specified intentions may not result in directives from the intention manager to the resource managers.
