摘要
目前,我们需要能够实时对军事形势进行准确、全面评估的融合系统。这项工作的目标是定义、原型开发和演示经济实惠的下一代 JDL 2 级融合和利用架构。这项工作的范围包括确定当前 2 级融合评估系统中阻碍其提供实时评估的限制性标准。利用这一标准和对硬件要求贸易空间的评估,提出了由硬件和软件方法组成的解决方案,包括对成本影响的评估。然后,将这些解决方案应用于现有的最先进的 2 级融合系统,即纽约州罗马市斯特林软件公司开发的节点开发应用工具包,从而验证了这些解决方案的有效性。这项工作成功地在纽约州罗马市空军研究实验室罗马研究基地的 Linux 集群上演示了原型。性能改进不仅限于在多个处理器上并行处理现有算法。顺序算法处理也得到了优化。与在 Linux PC 上运行的原始软件相比,结果显示在单个处理器上速度提高了 30 倍,在 4 个处理器上并行运行时速度提高了 63 倍。
There currently exists the need for fusion systems that can provide an accurate and comprehensive assessment of military situations in real-time. The objective of this effort was to define, prototype, and demonstrate an affordable next-generation JDL Level 2 fusion and exploitation architecture. The scope of this effort included the identification of the limiting criteria in current Level 2 fusion assessment systems that inhibit them from providing real-time assessment. Using this criterion and assessment of the hardware requirements trade space, solutions were proposed consisting of both hardware and software approaches including an assessment of cost impact. The validity of the solutions were then validated by applying them to an existing state-of-the-art Level 2 fusion system, the Nodal Exploitation Application Toolkit developed by Sterling Software; Rome, NY. The effort succeeded in providing a demonstration of the prototype on a Linux Cluster at the Air Force Research Laboratorys' Rome Research Site, in Rome, NY. Performance improvements were not limited to parallelizing existing algorithms across multiple processors. The sequential algorithmic processing was optimized as well. Compared to the original software running on a Linux PC, results show 30 times speed improvement on a single processor, 63 times speed improvement when run in parallel across 4 processors.
