With the advent of multi-core platforms, research in the field of hard real-time has recently considered parallel software, from the perspective of both worst-case execution time (WCET) and task schedulability (or worst-case response time, WCRT) analyses. These two areas consider task models that are not completely identical and sometimes make different assumptions. This paper draws a brief overview of the state of the art in the timing analysis of parallel tasks and tries to identify points of convergence and divergence between the existing approaches.
