Abstract:

A system, method, and computer program product for management of dynamic task-dependency graphs. The method includes the steps of generating a first task data structure in a memory for a first task, generating a second task data structure in the memory, storing a pointer to the second task data structure in a first output dependence field of the first task data structure, setting a reference counter field of the second task data structure to a threshold value that indicates a number of dependent events associated with the second task, and launching the second task when the reference counter field stores a particular value. The second task data structure is a placeholder for a second task that is dependent on the first task.
