Abstract: A processor includes a controller and plurality of chiplets, each chiplet including a plurality of processor cores. The controller provides chiplet-level performance information for the chiplets that identifies a performance of each chiplet at each of a plurality of performance levels for specified sets of processor cores on that chiplet. The controller receives an identification of one or more selected chiplets from among the plurality of chiplets for which a specified number of processor cores are to be configured at a given performance level, the one or more selected chiplets having been selected based on the chiplet-level performance information and performance requirements. The controller configures the specified number of processor cores of the one or more selected chiplets at the given performance level. A task is then run on the specified number of processor cores of the one or more selected chiplets at the given performance level.

Abstract: A technique for processing qubits in a quantum computing device is provided. The technique includes determining that, in a first cycle, a first quantum processing region is to perform a first quantum operation that does not use a qubit that is stored in the first quantum processing region, identifying a second quantum processing region that is to perform a second quantum operation at a second cycle that is later than the first cycle, wherein the second quantum operation uses the qubit, determining that between the first cycle and the second cycle, no quantum operations are performed in the second quantum processing region, and moving the qubit from the first quantum processing region to the second quantum processing region.

Abstract: An electronic device handles memory access requests for data in a memory. The electronic device includes a memory controller for the memory, a last-level cache memory, a request generator, and a predictor. The predictor determines a likelihood that a cache memory access request for data at a given address will hit in the last-level cache memory. Based on the likelihood, the predictor determines: whether a memory access request is to be sent by the request generator to the memory controller for the data in parallel with the cache memory access request being resolved in the last-level cache memory, and, when the memory access request is to be sent, a type of memory access request that is to be sent. When the memory access request is to be sent, the predictor causes the request generator to send a memory request of the type to the memory controller.

Abstract: Methods and systems for opportunistic load balancing in deep neural networks (DNNs) using metadata. Representative computational costs are captured, obtained or determined for a given architectural, functional or computational aspect of a DNN system. The representative computational costs are implemented as metadata for the given architectural, functional or computational aspect of the DNN system. In an implementation, the computed computational cost is implemented as the metadata. A scheduler detects whether there are neurons in subsequent layers that are ready to execute. The scheduler uses the metadata and neuron availability to schedule and load balance across compute resources and available resources.

Abstract: The described embodiments include an apparatus that controls voltages for an integrated circuit chip having a set of circuits. The apparatus includes a switching voltage regulator separate from the integrated circuit chip and two or more low dropout (LDO) regulators fabricated on the integrated circuit chip. The switching voltage regulator provides an output voltage that is received as an input voltage by each of the two or more LDO regulators, and each of the two or more LDO regulators provides a local output voltage, each local output voltage received as a local input voltage by a different subset of the circuits in the set of circuits. During operation, a controller sets an operating point for each of the subsets of circuits based on a combined power efficiency for the subsets of the circuits and the LDO regulators, each operating point including a corresponding frequency and voltage.

Abstract: Systems, apparatuses, and methods for implementing mechanisms to improve data locality for distributed processing units are disclosed. A system includes a plurality of distributed processing units (e.g., GPUs) and memory devices. Each processing unit is coupled to one or more local memory devices. The system determines how to partition a workload into a plurality of workgroups based on maximizing data locality and data sharing. The system determines which subset of the plurality of workgroups to dispatch to each processing unit of the plurality of processing units based on maximizing local memory accesses and minimizing remote memory accesses. The system also determines how to partition data buffer(s) based on data sharing patterns of the workgroups. The system maps to each processing unit a separate portion of the data buffer(s) so as to maximize local memory accesses and minimize remote memory accesses.

Abstract: Systems, apparatuses, and methods for performing temperature-aware task scheduling and proactive power management. A SoC includes a plurality of processing units and a task queue storing pending tasks. The SoC calculates a thermal metric for each pending task to predict an amount of heat the pending task will generate. The SoC also determines a thermal gradient for each processing unit to predict a rate at which the processing unit's temperature will change when executing a task. The SoC also monitors a thermal margin of how far each processing unit is from reaching its thermal limit. The SoC minimizes non-uniform heat generation on the SoC by scheduling pending tasks from the task queue to the processing units based on the thermal metrics for the pending tasks, the thermal gradients of each processing unit, and the thermal margin available on each processing unit.
