WebFeb 7, 2024 · Previous researches on DAG task scheduling mainly restrict to only one level of parallelism. The problem whether OpenMP tasks with multiple levels of parallelism are suitable to real-time systems remains open. In this paper, we study the real-time scheduling and analysis of OpenMP task systems supporting nested parallelism. WebThe lower bound of a DAG's schedule length is the longest path in the DAG (called the critical path). When only the tasks in the critical path are submitted to a cluster with background workload, their schedule length can be viewed as the lower bound of the DAG’s schedule length in that cluster. Suppose a DAG's critical path consists ofk tasks, ,
