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

9224493 Bman该奖项将支持康奈尔大学的Kenneth Bman和Keith Marzullo以及里斯本技术大学的Paulo Verissimo之间的合作研究。Verissimo教授在INESC、系统和计算机工程研究所及其导航员小组工作，该小组的研究重点是分布式系统的健壮性。比尔曼教授与康奈尔大学的Isis项目有关；该项目的核心思想是鼓励程序员使用一组例程开发分布式软件，该例程提供了一种简单的网络执行模型--虚拟同步。目前，两个团队拥有最先进的知识，在某些方面是互补的。这两个小组的结论是，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可能会有实质性的进步。调查人员提议开展合作，在面向群体的计算新系统的总体框架下，整合各种高可靠性分布式计算技术。合作将涉及三个主题：将各种技术整合到一个群体计算环境中的面向对象的方法；利用操作系统社区中日益重要的微内核体系结构的系统体系结构问题的重点；以及实现这一愿景所需的协议和算法改进。***

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. ***
