Abstract

In this paper we address an end-to-end optimization problem in a distributed real-time system when a set of pipelined task chains are given. End-to-end deadlines and end-to-end jitter constraints are assumed to be given for task chains, in addition to an objective function to be optimized throughout the optimization process. The objective of the optimization process is to obtain local deadlines and other system parameters that not only satisfy all the given end-to-end constraints but also minimize a given objective function.

A separable programming technique is used to solve the resulting nonlinear programming problems. If an objective function and constraints satisfy a certain condition, it is shown that those problems can be solved by using a linear programming technique which already has well-established theories and results. Also, it is shown that the condition is general enough that a wide class of optimization problems can be solved in designing distributed real-time systems by using this technique.
