A method of workload scheduling in a distributed compute environment includes assigning a subscriber of a network service to a first compute node instance (“CNI”) of a plurality of CNIs within a network node interposed between the subscriber and a provider of the network service. The subscriber traffic associated with the subscriber is processed at the first CNI. Subscriber specific data is generated at the first CNI related to the subscriber traffic. The subscriber specific data is then backed up to a second CNI of the network node that is designated as a standby CNI that will process the subscriber traffic if the first CNI fails.

Systems and methods implementing a demand-driven workload scheduling optimization of shared resources used to execute tasks submitted to a computer system are disclosed. Some embodiments include a method for demand-driven computer system resource optimization that includes receiving a request to execute a task (said request including the task's required execution time and resource requirements), selecting a prospective execution schedule meeting the required execution time and a computer system resource meeting the resource requirement, determining (in response to the request) a task execution price for using the computer system resource according to the prospective execution schedule, and scheduling the task to execute using the computer system resource according to the prospective execution schedule if the price is accepted. The price varies as a function of availability of the computer system resource at times corresponding to the prospective execution schedule, said availability being measured at the time the price is determined.

A computer system that schedules loads across a set of processor cores is described. During operation, the computer system receives thermal measurements from sensors associated with the set of processor cores, and removes noise from the thermal measurements. Then, the computer system analyzes thermal properties of the set of processor cores based on the thermal measurements. Next, the computer system receives a process to be executed, and schedules the process to be executed by at least one of the processor cores based on the analysis. This scheduling is performed in a manner that reduces spatial and temporal thermal variations in the integrated circuit.

Various embodiments of methods and systems for thermally aware scheduling of workloads in a portable computing device that contains a heterogeneous, multi-processor system on a chip (“SoC”) are disclosed. Because individual processing components in a heterogeneous, multi-processor SoC may exhibit different processing efficiencies at a given temperature, and because more than one of the processing components may be capable of processing a given block of code, thermally aware workload scheduling techniques that compare performance curves of the individual processing components at their measured operating temperatures can be leveraged to optimize quality of service (“QoS”) by allocating workloads in real time, or near real time, to the processing components best positioned to efficiently process the block of code.

Techniques are described for scheduling received tasks in a data center in a manner that accounts for operating costs of the data center. Embodiments of the invention generally include comparing cost-saving methods of scheduling a task to the operating parameters of completing a task—e.g., a maximum amount of time allotted to complete a task. If the task can be scheduled to reduce operating costs (e.g., rescheduled to a time when power is cheaper) and still be performed within the operating parameters, then that cost-saving method is used to create a workload plan to implement the task. In another embodiment, several cost-saving methods are compared to determine the most profitable.

Method and system for providing a mechanism for determining an optimal workload distribution, from a plurality of candidate workload distributions, each of which has been determined to optimize a particular aspect of a workload-scheduling problem. More particularly, the preferred embodiment determines a workload distribution based on resource selection policies. From this workload distribution, the preferred embodiment optionally determines a workload distribution based on job priorities. From either or both of the above parameters, the preferred embodiment determines a workload distribution based on a total prioritized weight parameter. The preferred embodiment also determines a workload distribution which attempts to match the previously determined candidate workload distributions to a goal distribution. Similarly, the preferred embodiment calculates a further workload distribution which attempts to maximize job throughput.

The present invention relates to the field of enterprise network computing. In particular, it relates to a method and respective system for monitoring workload of a workload scheduler. Information defining a plurality of test jobs of low priority is received. The test jobs have respective launch times, and the test jobs are launched for execution in a data processing system in accordance with said launch times and said low execution priority. It is evaluated how many of said test jobs are executed within a pre-defined analysis time range. A performance decrease warning is issued, if the number of executed test jobs is lower than a predetermined threshold number. The workload scheduler discards launching of jobs having a low priority when estimating that a volume of jobs submitted with higher priority is sufficient to keep said scheduling system busy.

Operating system-directed workload scheduling of an adjunct partition in a logically partitioned computer is selectively overridden to handle platform work requiring a Quality of Service (QoS) guarantee. Firmware may track outstanding requests for platform work for an adjunct partition, and in response to a request for platform work that requires a QoS guarantee, the firmware may assume or take over scheduling decisions for the adjunct partition from the operating system of an associated logical partition and schedule execution of the adjunct partition to ensure that the adjunct partition will be allocated sufficient execution resources to perform the platform work independent of the scheduling desires of the operating system. As a result, any platform work that potentially impacts the platform work of other adjunct partitions will not be held up as a result of an unwillingness or inability of the operating system to schedule execution of the adjunct partition.

A method for scheduling execution of a work unit in a data processing system (100) comprises assigning to the work unit an expected execution duration (PD); executing the work unit (315); determining an actual execution duration (AD) of the work unit (320); determining a difference between the actual execution duration and the expected duration; and conditionally adjusting (345,350,355) the expected execution duration assigned to the work unit based on the measured actual execution duration, wherein the conditionally adjusting includes preventing the adjustment of the expected execution duration in case said difference exceeds a predetermined threshold (LF). The method further includes associating to the work unit a parameter (NLF) having a prescribed value adapted to provide an indication of unconditional adjustment of the expected execution duration: in case said parameter takes the prescribed value, the expected duration assigned with the work unit based on the measured actual execution duration even if the difference in durations exceeds the predetermined threshold.

Operational modes may be determined by the recognition of one or more mode-decision conditions in the PCD.

A method of automatically optimizing workload scheduling. Target values for workload characteristics and constraint specifications are received. Generation of a first execution plan is initiated. Initial constraint values conforming to the constraint specifications are selected. Each constraint value constrains tasks included in the workload. The first execution plan is executed, thereby determining measurements of workload characteristics. Contributions indicating differences between workload characteristic measurements and target values are determined and stored. Generation of a next execution plan is initiated. Modified constraint values conforming to the constraint specifications are selected. Changes in the workload characteristics based on the modified constraint values are evaluated. An optimal or acceptable sub-optimal solution in a space of solutions defined by the constraint specifications is determined, resulting in new values for the constraints. After replacing the initial values with the new values, the next execution plan is generated and executed.

Various embodiments of methods and systems for dynamically adjusting operating frequency settings of one or more processing components in a portable computing device (“PCD”) are disclosed. One such method involves receiving a request to adjust an operating frequency setting of a processing component to a required frequency (“F_req”) to process a workload. Factor readings associated with the operating capacity of the processing component may be taken. Based on the readings, performance curves associated with the processing component may be queried. The performance curves are used to determine the optimal operating frequency (“F_opt”) for the processing component. The F_opt is compared to the F_req and, if the F_req is less than F_opt, the operating frequency setting of the processing component is set to F_opt. Advantageously, as compared to F_req, at F_opt workload processing may be more efficient and a low power mode may be entered sooner.
