NSF-CGP Science Fellowship Program: Parallelization and Implementation of Production Systems on the EM-4 Data-Flow Multiprocessor

9310972 Sohn Japan CGP计划：EM4数据流多处理器生产系统的并行化和实施该奖项将使新泽西理工学院的Andrew Sohn博士能够与西田贤二博士在日本筑波电工实验室的计算机科学部进行为期三个月的合作研究。该团队将研究生产系统中的并行性，并在EM4数据流多处理器上实现一个并行化系统。日本工业产业省目前资助了一个大型多研究所项目，以开发一种并行处理计算机系统。作为该项目的一部分，电工实验室设计并建造了四代实验数据流多处理机。第四代机器EM4由80个处理器组成，目前正在接受西田博士的测试，以确定它是否能够有效和快速地处理大型和现实的问题。利用Sohn博士在非数值问题(如产生式系统解释器)方面的专业知识，西田和Sohn将并行处理两种类型的产生式系统，将这些产生式系统的功能和数据划分并分配给多处理器，然后执行这些系统。该团队将评估EM4的性能，并确定在多处理器上执行全面实际问题所需的任何改进。

9310972 Sohn Japan CGP Program: Parallelization and Implementation of Production Systems on the EM 4 Data Flow Multiprocessor This award will enable Dr. Andrew Sohn of the New Jersey Institute of Technology to conduct collaborative research with Dr. Kenji Nishida for three months at the Computer Science Division of the Electrotechnical Laboratory in Tsukuba, Japan. The team will investigate parallelism in production systems and implement a parallelized system on the EM 4 data flow multiprocessor. The Japanese Ministry of Industrial Trade and Industry currently funds a large multi institute project to develop a parallel processing computer system. As part of this project, the Electrotechnical Laboratory has designed and constructed four generations of experimental data flow multiprocessing machines. The fourth generation machine, EM 4, is comprised of 80 processors and is currently being tested by Dr. Nishida to determine whether it can effectively and quickly execute large and realistic problems. Utilizing Dr. Sohn's expertise in non numeric problems such as production system interpreters, Nishida and Sohn will parallelize two types of production systems, partition and assign the functions and data of those production systems to the mulitprocessor, and execute the systems. The team will evaluate the performance of the EM 4 and determine any improvements which would be needed to perform full scale real problems on the multiprocessor.
