摘要:
A safety thread scheduler configured to schedule a check thread for a critical thread being run on one of a plurality of execution units, the check thread being a duplicate of the critical thread, wherein the safety thread scheduler is configured to schedule the check thread to begin being run on a second one of the plurality of execution units before the end of a safety time-window for scheduling the check thread. The safety thread scheduler is further configured to allow the check thread, when the check thread is running on the second one of the plurality of execution units, to be interrupted by a further thread and to re-schedule the check thread to be resumed by expiry of a re-scheduling time limit.

A method for operating a multithread processing system is provided, including assigning, by a controller, a subset of a plurality of tasks to a plurality of threads during a time N, collecting, by the controller, data during the time N concerning the operation of the plurality of threads, analyzing, by the controller, the data to determine at least one condition concerning the operation of the plurality of threads during the time N, and adjusting, by the controller, a number of the plurality of threads available in time N+1 in accordance with the at least one condition.

Techniques are for rule-based continuous drift and consistency management for target systems. In one embodiment, a set of rules is stored in volatile or non-volatile store. The set of rules may include one or more drift rules and/or one or more consistency rules. A rule may be applied to one or more associated targets to detect drift or inconsistency. A drift rule identifies a set of one or more attributes and a source and may be applied by comparing a first configuration of the set of one or more attributes on an associated target with a second configuration of the set of one or more attributes on the source. A consistency rule may be applied to a composite target by comparing member targets that are grouped by target type. Notification data may be output if target drift or inconsistency is detected to alert a user.

Technologies are described herein for event delivery and stream processing utilizing virtual processing agents. Upon receiving an event publication in a queue, a runtime system identifies one or more virtual processing agents that might be interested in, but have not explicitly subscribed to, the published event. Event information of the published event is then delivered to the identified virtual processing agents. Prior to the actual delivery, the runtime system further determines if the virtual processing agents have been activated and activates those processing agents that have not been activated. Based on the received event information, some of the virtual processing agents might decide to explicitly submit subscriptions to receive more events from the queue. The explicit subscriptions will trigger the runtime system to deliver the subscribed events to the processing agents, which might include past events that have been published in the queue before the explicit subscription is received.
摘要:
A method for executing multithreaded instructions grouped into blocks. The method includes receiving an incoming instruction sequence using a global front end; grouping the instructions to form instruction blocks, wherein the instructions of the instruction blocks are interleaved with multiple threads; scheduling the instructions of the instruction block to execute in accordance with the multiple threads; and tracking execution of the multiple threads to enforce fairness in an execution pipeline.

Managing virtual and real machines through a provisioning system. The provisioning system allows a user to create and manage machines through a "self-service" approach. The provisioning system interacts with one or more agents that manage the lifecycle of a machine. The system may provide templates that enable a user to readily create a virtual machine. The system may also include interfaces for administrators to manage virtual and real machine resources.
