Abstract: Systems, apparatuses, and methods for balancing computation and communication power in power constrained environments. A data processing cluster with a plurality of compute nodes may perform parallel processing of a workload in a power constrained environment. Nodes that finish tasks early may be power-gated based on one or more conditions. In some scenarios, a node may predict a wait duration and go into a reduced power consumption state if the wait duration is predicted to be greater than a threshold. The power saved by power-gating one or more nodes may be reassigned for use by other nodes. A cluster agent may be configured to reassign the unused power to the active nodes to expedite workload processing.

Abstract: Systems, apparatuses, and methods for achieving balanced execution in a multi-node cluster through runtime detection of performance variation are described. During a training phase, performance counters and an amount of time spent waiting for synchronization is monitored for a plurality of tasks for each node of the multi-node cluster. These values are utilized to generate a model which correlates the values of the performance counters to the amount of time spent waiting for synchronization. Once the model is built, the values of the performance counters are monitored for a period of time at the start of each task, and these values are input into the model. The model generates a prediction of whether a given node is on the critical path. If the given node is predicted to be on the critical path, the power allocation of the given node is increased.

Abstract: Power gating decisions can be made based on measures of cache dirtiness. Analyzer logic can selectively power gate a component of a processor system based on a cache dirtiness of one or more caches associated with the component. The analyzer logic may power gate the component when the cache dirtiness exceeds a threshold and may maintains the component in an idle state when the cache dirtiness does not exceed the threshold. Idle time prediction logic may be used to predict a duration of an idle time of the component. The analyzer logic may then selectively power gates the component based on the cache dirtiness and the predicted idle time.

Abstract: A three-dimensional (3-D) processor stack includes a plurality of processor cores implemented in a plurality of layers. A controller is to selectively throttle one or more of a plurality of processor cores in response to detecting a thermal event. The controller selectively throttles the one or more of the plurality of processor cores based on values of thermal couplings between the plurality of layers and based on measures of criticality of threads executing on the plurality of processor cores.

Abstract: Systems, methods, and devices for integrated circuit power management. A mode of a power management state is entered, from the power management state, in response to an entry condition of the mode. A device that is otherwise powered off in the power management state is powered on in the mode of the power management state. In some implementations, the device includes a communications path between a second device and a third device. In some implementations, the device is in a power domain that is powered off in the power management state. In some implementations, the power domain is powered off in the mode. In some implementations, the device is powered on in the mode via a power rail that is specific to the mode. In some implementations, the entry condition of the mode includes an amount of data stored for display in a display buffer falling below a threshold amount.
