摘要

数据流是表示分布式程序的一种自然范例,能够表示组合实体(节点)之间的数据(和控制)依赖关系。我们的工作集中在具有硬实时约束的数据流程序;我们考虑的是周期程序,但该方法也可以应用于零星和非周期程序。我们提出了一种方法,如果可能的话,为系统中每个程序节点找到一个可行的执行时间分配,给出一个启发式映射。

A schedulability algorithm for data flow, hard-real-time distributed programs

Data Flow is a natural paradigm representing distributed programs able to express the data (and control) dependencies between composing entities (nodes). Our work concentrates on Data Flow programs having Hard-Real-Time constraints; we consider periodic programs but the method can also be applied to sporadic and aperiodic ones. We propose a method to find, if possible, a feasible execution time assignment for each program node in the system, given a heuristic mapping.
