U.S.-Austria Cooperative Research on Virtual Shared Memory for Distributed-Memory Machines (Computer Science)

该奖项支持Ken Kennedy教授和他在莱斯大学的其他人与现任维也纳大学的Hans Zima教授在计算机科学研究方面保持合作。作为“ParaScope”项目的一部分，莱斯大学团队多年来一直致力于分布式存储机器的编程环境。与此同时，齐马教授一直在为SUPRENUM项目构建一个类似的静态数据分区系统，名为Superb。在莱斯的一次休假访问期间，合作者开发了一种增强的系统，该系统朝着提高适应性的动态分区方向发展。他们的设计使用了对用数据分区语言编写的FORTRAN程序的注释。用户提供注释。然后，底层编译系统将FORTRAN程序转换为分布式存储器程序，该程序采用由注释指定的数据分配策略。缺乏高效的并行和分布式硬件编译程序阻碍了许多学科的科学家有效地利用新的分布式计算资源。赖斯集团在这一领域的主要研究得到了美国国家科学基金会对那里的一个科学技术中心的资助。由于齐马教授已返回欧洲，与他保持积极合作，将是这项位于德克萨斯州的工作的一项廉价而有价值的改进。

This award supports Professor Ken Kennedy and others in his group at Rice University to maintain collaboration in computer science research with Professor Hans Zima now of the University of Vienna. The Rice University team has been working for several years on a programming environment for distributed-memory machines as part of the "ParaScope" project. Simultaneously, Professor Zima has been building a similar static data partitioning system, called SUPERB, for the SUPRENUM project. During a sabbatical visit at Rice, the collaborators developed an enhanced system that moves toward dynamic partititioning that increases adaptability. Their design uses annotations to a FORTRAN program written in a data partitioning language. The user provides the annotation. The underlying compilation system then translates the FORTRAN program to a distributed memory program that employs the data assignment strategy specified by the annotations. Lack of efficient compiling programs for parallel and distributed hardware stands in the way of effective use of the new distributed computing resources by scientists in many disciplines. The principal research of the Rice group in this area is supported by an NSF grant to a Science and Technology Center there. Maintaining active collaboration with Professor Zima, now that he has returned to Europe, will be an inexpensive and valuable enhancement to the Texas-based work.
