1. A method for allocating resources in a computing system providing a computing service to one or more clients, the method comprising:
- receiving parameters from the one or more clients for multiple flows associated with the one or more clients, the parameters including at least a target priority and a target performance for each of the multiple flows;
for each of the multiple flows, converting the target performance into a measurable characteristic and determining a current performance based on the measurable characteristic;
determining a current priority for each of the multiple flows executing in the computing system, wherein the current priority is based on the target priority, the target performance and the current performance;
scheduling the multiple flows for a schedule block based on the current priorities, wherein each schedule block corresponds to a predetermined period of time;
allocating resources to the multiple flows based on relative current priorities of the multiple flows for the schedule block;
updating the current priority of each of the multiple flows for a next schedule block; and
reallocating the resources to the multiple flows for the next schedule block based on the relative updated current priorities.

Abstract
Systems and methods for scheduling multiple flows in a computing system or for allocating resources to the flows in the computing system. Each flow may be associated with a target priority and a target performance. A current priority can be determined for each flow and resources are allocated based on the highest current priority. Over time, the current priorities change and each flow will receive resources as the flows are scheduled for execution. No flow is starved of resources.

6. A method of scheduling flows in a computing environment, the method comprising:
-
providing storage to multiple tenants in a computing system configured to provide a computing service to the tenants, wherein the storage of each tenant is associated with a storage quota, wherein each entity is associated with multiple objects and each object is associated with a flow; receiving parameters from the tenants in for the flows associated with the tenants, the parameters including at least a target priority and a target performance for each of the flows; determining a current performance for each of the flows by converting the target performance into a measurable characteristic; determining a current priority for each flow executing in the computing system based on the target performance; scheduling the flows for a schedule block based on the current priorities, wherein each schedule block corresponds to a predetermined period of time and wherein the flow with the highest priority is given priority access to resources of the computing system for the schedule block; for a next schedule block, updating the current priorities of the flows and giving prioritized access to the resources to the flow with the highest updated current priority during the next schedule block. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A computing system configured to provide a computing service to one or more clients, wherein each client is associated with one or more objects, the computing system comprising:
-
a storage device, wherein the objects are stored in the storage; computing resources including at least processing resources; and a scheduler that includes computer executable instructions that, when executed, perform a method for scheduling flows associated with the objects, the method comprising; receiving parameters from the one or more clients for multiple flows associated with the one or more clients, the parameters including at least a target priority and a target performance for each of the multiple flows; for each of the multiple flows, determining a current performance by converting the target performance into a measurable characteristic; determining a current priority for each of the flows executing in the computing system, wherein the current priority is based on the target priority, the target performance and a current performance when the current performance is less than the target performance and wherein the current priority is based on an excess priority, the target performance and the current performance when the current performance is equal to or greater than the target performance; scheduling the multiple flows for a schedule block based on the current priorities, wherein each schedule block corresponds to a predetermined period of time; allocating resources to the multiple flows based on relative current priorities of the multiple flows for the schedule block; updating the current priority of each of the multiple flows for a next schedule block; and reallocating the resources to the multiple flows for the next schedule block based on the relative updated current priorities. - View Dependent Claims (15)
