Abstract:
Virtual machines are provided on-demand. This on-demand service is beneficial in many situations, including, for instance, providing a virtual machine on-demand to process a request. The virtual machine provided to process the request is exclusive to the request. The on-demand virtual machine is automatically activated by another virtual machine, which has control over the on-demand virtual machine. The controlling virtual machine manages the start-up, provision of resources, and the shut-down of the on-demand virtual machine.
Abstract:
Allocation of resources in a heterogeneous computing environment is facilitated A resource manager of the heterogeneous computing environment obtains information that describes which nodes of the heterogeneous computing environment are capable of supporting additional operating systems and platforms over and above their native operating systems and platforms. This information is then used by the resource manager in allocating resources to satisfy a particular job.

Abstract:
Under the present invention, a wireless sensor network comprising a plurality of peer to peer nodes is provided. Each node in the network includes, among other things, a sensor for detecting environmental factors. When a potential failure is detected within a node, the node will query its neighboring nodes to determine whether they have the capability to store any data component(s) currently stored within the potentially failing node. Based on the querying, the data component(s) in the potentially failing node are copied to one or more of the neighboring nodes. Thereafter, details of the copying can be broadcast to other nodes in the network, and any routing tables that identify the locations of data components stored throughout the wireless sensor network can be updated.

Abstract:
The present invention enables fast transition between sleep and normal modes for circuits such as digital circuits. This invention utilizes chip internal charge transfer operations to put the circuit into fast sleep. The invention reduces external power involvement, and it expedites the sleep mode transition time by limiting charge transfers within the circuit. The fast sleep and fast wake-up enable more efficient power management of the system. This functionality also maximizes performance per power, and provides a more energy efficient computing architecture.
Abstract:
System and method are provided for continually monitoring reliability, or aging, of a digital system and for issuing a warning signal if digital system operation degrades past a specified threshold. The technique includes implementing a ring oscillator sensor in association with the digital system, wherein logic and/or device percent composition of the ring oscillator sensor mirrors percent composition thereof within the digital system. Counter logic is coupled to the ring oscillator sensor for converting outputted count signals to an oscillation frequency, and control logic is coupled to the counter logic for periodically evaluating oscillation frequency of the ring oscillator sensor and generating a warning signal indicative of reliability degradation if at least one of: (i) a measured or estimated oscillation frequency is below a warning threshold frequency; or (ii) a measured or estimated rate of change in a difference between measured oscillation frequencies exceeds an acceptable rate of change threshold.
