Oversubscription scheduling
A system for adjusting oversubscription loading includes an interface and a processor. The interface is configured to receive a set of performance data from a set of worker systems. The processor is configured to determine a feedback indication for a worker system of the set of worker systems based at least in part on the set of performance data. The feedback indication is used to adjust an oversubscription controller on the worker system. The processor is configured to provide the feedback indication to the worker system.
1. A system for oversubscription loading and control, comprising:
a storage medium having stored thereon a sequence of instructions; and
a processor that executes the sequence of instructions to cause a set of acts comprising:
receiving a first set of performance data representing performance of respective workloads under a first set of conditions;
determining placement of the respective workloads using the first set of performance data corresponding to the first set of conditions, wherein two or more workloads are placed on a worker system of a set of worker systems that is configured to allow oversubscription, and the worker system is oversubscribed after the two or more workloads are placed on the worker system;
receiving a second set of performance data from the set of worker systems representing performance of the two or more workloads on the worker system under a second set of conditions;
determining a feedback indication for the worker system of the set of worker systems based at least in part on the second set of performance data, wherein the feedback indication is determined based on the second set of performance data and comprises an indication to evict a workload of the two or more workloads from the worker system; and
providing the feedback indication to the worker system.
2. The system of claim 1 , wherein the feedback indication is based at least in part on a stability indicator or task interference.
3. The system of claim 1 , wherein the feedback indication is based at least in part on a classification of performance data, and the classification of performance data comprises a processor intensive classification, a memory intensive classification, or a network access intensive classification.
4. The system of claim 1 , wherein the feedback indication is used to adjust an eviction criteria on an oversubscription controller, and the eviction criteria comprises newest first, most processor use first, most memory use first, or most network use first.
5. The system of claim 1 , wherein the second set of perform data corresponds to a drop in performance of a corresponding workload when compared to the first set of performance data.
6. The system of claim 5 , wherein the workload is evicted when the drop in performance exceeds a threshold value for a corresponding parameter.
7. The system of claim 1 , wherein low priority workloads are evicted before high priority workloads.
8. The system of claim 1 , wherein the first set of performance data represents performance of the respective workloads without an interfering workload present, and the second set of performance data represents performance of the two or more workloads on the oversubscribed worker system.
9. A method for oversubscription loading and control, comprising:
receiving a first set of performance data representing performance of respective workloads under a first set of conditions;
determining placement of the respective workloads using the first set of performance data corresponding to the first set of conditions, wherein two or more workloads are placed on a worker system of a set of worker systems that is configured to allow oversubscription, and the worker system is oversubscribed after the two or more workloads are placed on the worker system;
receiving a second set of performance data from the set of worker systems representing performance of the two or more workloads on the worker system under a second set of conditions;
determining a feedback indication for the worker system of the set of worker systems based at least in part on the second set of performance data, wherein the feedback indication is determined based on the second set of performance data and comprises an indication to evict a workload of the two or more workloads from the worker system; and
providing the feedback indication to the worker system.
10. The method of claim 9 , wherein the second set of perform data corresponds to a drop in performance of a corresponding workload when compared to the first set of performance data.
11. The method of claim 10 , wherein the workload is evicted when the drop in performance exceeds a threshold value for a corresponding parameter.
12. The method of claim 9 , wherein low priority workloads are evicted before high priority workloads.
13. The method of claim 9 , wherein the first set of performance data represents performance of the respective workloads without an interfering workload present.
14. The method of claim 13 , wherein the second set of performance data represents performance of the two or more workloads on the oversubscribed worker system.
15. A computer program product for oversubscription loading and control, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions which, when executed by a processor, causes a set of acts comprising:
receiving a first set of performance data representing performance of respective workloads under a first set of conditions;
determining placement of the respective workloads using the first set of performance data corresponding to the first set of conditions, wherein two or more workloads are placed on a worker system of a set of worker systems that is configured to allow oversubscription, and the worker system is oversubscribed after the two or more workloads are placed on the worker system;
receiving a second set of performance data from the set of worker systems representing performance of the two or more workloads on the worker system under a second set of conditions;
determining a feedback indication for the worker system of the set of worker systems based at least in part on the second set of performance data, wherein the feedback indication is determined based on the second set of performance data and comprises an indication to evict a workload of the two or more workloads from the worker system; and
providing the feedback indication to the worker system.
