Abstract : We investigate the global scheduling of sporadic, implicit deadline, real-time task systems on identical multiprocessor platforms. We provide a task model which integrates work-limited job parallelism. For work-limited parallelism, we prove that the time-complexity of deciding if a task set is feasible is linear relatively to the number of (sporadic) tasks for a fixed number of processors. Based on this proof, we propose an optimal scheduling algorithm. Moreover, we provide an \emph{exact} feasibility utilization bound.
