摘要： 实时并行系统是并行/分布系统的重要组成部分，它要求系统计算时间具有可预测性，即符合应用要求的硬性响应时间约束。根据该特点，分析影响实时并行系统性能的各种因素，设计并实现一种简单的实时并行系统评测方案，并在实验室对C3I实时集群系统进行评测，从而验证该方案的有效性。

Abstract: Real-time parallel system is important part of parallel/distributed system, which requires predictability for system computing time, and fits the response time constrait. According to this character, the real-time functions of real-time parallel system are analyzed, and a simple test method of real-time cluster computing is designed and realized. The test process and results of real-time cluster computing in laboratory are given, which proves it is an effective test method.

Key words: real-time parallel system, test, performance, predictability, latency time
