Περίληψη:
In this paper we present a new synchronization strategy for real-time
tasks executed in a distributed environment. This strategy makes the
timing properties of the system predictable since one is able to
determine analytically whether the timing requirements of a task set
will be met, and if not, which task timing requirements will fail. In
particular, every task is allocated on a different node of a distributed
system and can require the use of non-preemptable resources or access
shared data. The proposed synchronization protocol is based on the
on-demand paradigm where resources are assigned only when actually
required so that the system never wastes unused assignments. Simple
formulae for the worst-case determination of task blocking durations as
well as for the schedulability analysis of a set of tasks are described.
A schedulability analysis example is also presented that illustrates the
concepts of scheduling and resource allocation of a set of time critical
tasks.
