Abstract
In a cyclic executive, a series of pre-determined frames are
executed in sequence; once the series is complete the sequence is repeated.
Within each frame individual units of computation are executed, again in
a pre-specified sequence. The implementation of cyclic executives upon
multi-core platforms is considered. A Linear Programming (LP) based
formulation is presented of the problem of constructing cyclic executives
upon multiprocessors for a particular kind of recurrent real-time
workload – collections of implicit-deadline periodic tasks. Techniques are
described for solving the LP formulation under different kinds of restrictions
in order to obtain preemptive and non-preemptive cyclic executives.
