Abstract
Recently, the negative effect of the popular power
management technique Dynamic Voltage and Frequency
Scaling (DVFS) on the system reliability has been iden-
tified. As a result, various reliability-aware power
management (RAPM) schemes have been studied for
uniprocessor real-time systems. In this paper, we in-
vestigate global-scheduling-based RAPM (G-RAPM)
schemes for a set of frame-based real-time tasks run-
ning on a homogeneous multiprocessor system. An im-
portant dimension of the problem is how to select the
appropriate subset of tasks for energy and reliability
management (i.e., schedule a recovery for each selected
