A Synchronous Transition Protocol with Periodicity for Global Scheduling of Multimode Real-Time Systems on Multiprocessors
Ref: HURRAY-TR-091101 Publication Date: 1 to 4, Dec, 2009Abstract:
We consider the global scheduling problem of
multimode real-time systems upon identical multiprocessor
platforms. During the execution of a multimode system, the system
can change from one mode to another such that the current
task set is replaced with a new task set. Thereby, ensuring that
deadlines are met requires not only that a schedulability test
is performed on tasks in each mode but also that (i) a protocol
for transitioning from one mode to another is specified and (ii)
a schedulability test for each transition is performed. In this
paper, we extend the synchronous transition protocol SM-MSO
in order to take into account mode-independent tasks [1], i.e.,
tasks of which the execution pattern must not be jeopardized
by the mode changes.
