U.S.-Portugal Cooperative Research between INESC Portugal and Cornell ISIS: Group-Oriented Distributed Computing.

该奖项将支持康奈尔大学的Kenneth Birman和Keith Marzullo以及里斯本技术大学的Paulo Verissimo之间的合作研究。Verissimo教授与系统与计算机工程研究所（INESC）及其导航组（Navigators Group）有联系，该小组的研究重点是分布式系统的鲁棒性。伯曼教授参与了康奈尔大学的Isis项目；它的中心思想是鼓励程序员使用一组例程来开发分布式软件，这些例程提供了一个简单的网络执行模型，即虚拟同步。目前，这两个团队拥有最先进的知识，在某些方面是互补的。两个小组都得出结论，通过整合独立开发的技术，下一代分布式计算系统的易用性和能力将得到实质性的提升。研究人员建议在一个面向群体计算的新系统的总体框架下，共同努力整合各种高可靠性分布式计算技术。这项合作将涉及三个主题：面向对象的方法，用于将各种技术集成到群组计算环境中；关注系统架构问题，利用在操作系统社区中越来越重要的微内核架构；而实现这一愿景所需要的协议和算法的增强。＊＊＊

9224493 Birman This award will support collaborative research between Kenneth Birman and Keith Marzullo, Cornell University, and Paulo Verissimo, Technical University of Lisbon. Professor Verissimo is associated with INESC, the Institute for Systems and Computer Engineering, and its Navigators Group, whose research focuses on robustness of distributed systems. Professor Birman is associated with the Isis Project at Cornell; its central idea is to encourage programmers to develop distributed software using a collection of routines that presents a simple network execution model, virtual synchrony. At present, the two teams hold state-of-the-art knowledge which is in some points complementary. Both groups have concluded that by integrating independently developed technologies, a substantial advance in the ease of use and power of the next generation of distributed computing systems could result. The investigators propose to collaborate on an effort that will integrate a diverse collection of high reliability distributed computing technologies under the general framework of a new system for group-oriented computing. The collaboration will deal with three subjects: an object-oriented methodology for integration of varied technologies into a group computing environment; a focus on system architecture issues drawing on the microkernel architectures that are gaining in importance within the operating systems community; and such protocol and algorithmic enhancements as are needed to realize that vision. ***
