Abstract
Techniques are disclosed for schedule management. By way of example, a method for managing performance of tasks of a thread associated with a processor comprises the following steps. A request to execute a task of a first task type within the thread is received. A determination is made whether the processor is currently executing a critical section of a task of a second task type within the thread. When it is determined that the processor is not executing a critical section of the second task type within the thread, the task of the first task type is executed within the thread. When it is determined that the processor is executing a critical section of the first task type within the thread, a determination is made whether the request for execution of the task of the first task type within the thread is deferrable based on a prior execution of one or more units of the first task type. The first task type may be an overhead task type such as a garbage collection task type, and the second task type may be an application task type.
