ABSTRACT:

The first generation of real-time scheduling algorithms was marked by the
invention and great success of the Rate Monotonic Analysis (RMA). Today,
tasks have more complex structures and are much more dynamic; consequently
RMA is very inefficient in handling these problems.  In contrast, soft
real-time scheduling analysis is a promising direction.  In order to
support efficient resource usage, we have been working to develop a theory
for the second generation of real-time scheduling system.  My talk will
cover: a new analytic theory, experimental validations, new system design
methods, analytical tools, new algorithms, implementation overhead
considerations.  During the theory development, we discovered a series of
phenomena in the new generation of scheduling systems that were unknown
previously to the real-time community. We also discovered some results
that are counter-intuitive.  These phenomena revealed interesting
properties of the new generation of real-time systems.
