Abstract. OpenMP 3.0 introduced the concept of asynchronous tasks, independent units of work that may be dynamically created and sched-uled. Task synchronization is accomplished via the insertion of taskwait and barrier constructs. However, the inappropriate use of these con-structs may incur significant overhead owing to global synchronizations for specific algorithms on large platforms. The performance of such al-gorithms may benefit substantially if a mechanism of specifying finer gained point-to-point synchronization between tasks is available. In this paper we present extensions to the current OpenMP task directive to enable the specification of dependencies among tasks. A task waits only until the explicit dependencies as specified by...
