Abstract
Starting and ending of a task is detected, where thread pooling is employed. Threads perform a wait operation on a given object are monitored, and threads performing a notify/notify-all operation on the given object are monitored. A labeled directed graph is constructed. Each node of the graph corresponds to one of the threads. Each edge of the graph has a label and corresponds to performance of the wait or notify/notify-all operation. An identifier of the given object is a label of a number of the edges. A set of nodes is selected that each has an edge having the same label. The threads of these nodes are worker threads of a thread pool. The threads of the nodes that are connected to the set of nodes are master threads. An object having an identifier serving as the label of the edges to the set of nodes is a monitoring mechanism.
