Abstract: The described implementations relate to processing of electronic data. One implementation is manifest as a system that can include logic and at least one processing device configured to execute the logic. The logic can be configured to receive a first task request to execute a first task that uses a resource when performed. The first task can have an associated first level of interactivity. The logic can also be configured to receive a second task request to execute a second task that also uses the resource when performed. The second task can have an associated second level of interactivity. The logic can also be configured to selectively throttle the first task and the second task based upon the first level of interactivity and the second level of interactivity.

Abstract: A power management and data center resource monitoring mechanism is provided for selecting new processing elements in a data center. When a condition is detected for selecting new processing elements, one or more processing elements are selected as the new processing elements based on at least a temperature parameter and a usage history parameter of at least some of the processing elements in the data center. Workload is consolidated onto the new processing elements to conserve energy.

Abstract: A device may receive information that identifies a first task to be processed, may determine a performance metric value indicative of a behavior of a processor while processing a second task, and may assign, based on the performance metric value, the first task to a bin for processing the first task, the bin including a set of processors that operate based on a power characteristic.

An example method includes, for each of a plurality of processors, retrieving a list of interrupt instances for a plurality of interrupt types; calculating an interrupt instance count value for each of the plurality of interrupt types; multiplying a corresponding weighting factor by the interrupt instance count value for each one of the plurality of interrupt types to generate a plurality of weighted interrupt values; calculating an overall weighted vector value based on the sum of the plurality of weighted interrupt values; and designating one of the plurality of processors as a selected processor based on the lowest overall weighted vector value.

Abstract: A system and method of managing a cluster of distributed machines is described. A cluster manager receives status updates regarding tasks running on each machine in the cluster from a task tracker running on the machine. The cluster manager receives resource requests from a job tracker created by a client wishing to run a job in the cluster. The cluster manager is responsible for implementing push-based fair scheduling of resources to the job trackers. The job tracker is responsible for running tasks for one job in the resource identified by the cluster manager. In one embodiment, the job tracker can run in the client for small jobs and in the cluster for larger jobs. The cluster manager can also be restarted, for example, for software updates without restraining the cluster.

Abstract: A method, apparatus, and computer readable article of manufacture for executing a transaction by a processor apparatus that includes a plurality of hardware threads. The method includes the steps of: executing, by the processor apparatus using the plurality of hardware threads, a main software thread for executing the transaction and a helper software thread for executing a barrier function; and deciding, by the processor apparatus, whether or not the barrier function is required to be executed when the main software thread encounters a transactional load or store operation that requires the main software thread to read or write data.

Abstract: A determination is made as to whether a creator of a created executable file is a trusted installer, e.g., a digitally signed installer. Upon a determination that the creator is a trusted installer, the created executable file is defined as a trusted file. By bestowing the trust of a trusted installer to the executable files that the installer creates, suspicious behavior by the created executable files and associated processes, which otherwise would be blocked, is allowed. In this manner, false positives, e.g., blocking of legitimate behavior by the created executable file and associated process(es), are avoided.

Abstract: Embodiments allow management software applications to distinguish computational assets without the use of static, predetermined identifiers that are susceptible to duplication along with computational assets. Managers and computational assets are associated with authenticator values. Additionally, a manager and computational asset determine (e.g., negotiate) an expected nonce (number used once) to be provided by either party when requesting a transaction. Upon receiving a transaction request associated with an authenticator value and a transaction nonce, the sender's knowledge of the expected nonce is proven when the nonce associated with the request matches the expected nonce, and disproven otherwise. When such knowledge is proven, the manager treats the computational asset as the one originally associated with the computational asset authenticator value and negotiates a new nonce.

Abstract: Methods and apparatus enforce computing policies of an enterprise in a distributed manner so that idiosyncratic services to a computing device can be minimized or altogether eliminated. Pluralities of virtual machines are arranged on one or more computing devices and define, for example, applications specified by a user and shared services approved by the enterprise. A central library stores the virtual machines and each is available for check-out by users. A manager evaluates the virtual machines for satisfactory compliance with the computing policies at a time when the virtual machines are resident in the library. Upon confirmation of satisfactory compliance, the applications and shared services are available for deployment to users. Otherwise, the virtual machines are centrally serviced for compliance and/or tested before redeployment. Libraries, managers, software program products, threat assessment, and policy management are other features, to name a few.
