Abstract
We consider the issue of deadline tardiness under global
multiprocessor scheduling algorithms. We present a general
tardiness­bound derivation that is applicable to a wide
variety of such algorithms (including some whose tardiness
behavior has not been analyzed before). Our derivation is
very general: job priorities may change rather arbitrarily
at runtime, arbitrary non­preemptive regions are allowed,
and capacity restrictions may exist on certain processors.
Our results show that, with the exception of static­priority
algorithms, most global algorithms considered previously
have bounded tardiness. In addition, our results provide
a simple means for checking whether tardiness is bounded
under newly­developed algorithms.
