US Patent 9491112 Allocating processor resources based on a task identifier

Techniques are described for accumulating unused computing resources. The techniques may involve receiving a request to execute a task for a tenant on shared hardware resources and assigning a task identifier to the task. A baseline resource credit per time interval of a computing resource can be determined based on a service level agreement associated with the tenant. The techniques may further involve monitoring a performance counter associated with the computing resource to determine a utilization amount of the computing resource by the task during a first time interval, determining an unused amount of the computing resource in the first time interval based on a difference between the utilization amount and the baseline resource credit and incrementing a resource credit balance associated with the task identifier by the unused amount of the computing resource.
