Proposal CCR-9972571Title: Kan: A Platform for Reliable Distributed ObjectsPI: Ambuj K SinghThe goal of the project is to design and implementa distributed object-oriented system for supporting large and complex parallel and distributed applications. The system supports a simple, yet powerful, programming model with thefollowing language features: asynchronous method calls, concurrent threads, guards, nested transactions, and objects that can be migrated and replicated transparently. The system achieves efficiency and scalability through dynamic runtime optimizations such as an adaptive thread pool,thread inlining, monitoring of object access patterns,and dynamic clustering and granularity.The system is resilient to node failures; this is attainedthrough low-overhead algorithms for logging and recovery.Investigating weaker notions of object consistency that allow reduced communication between processorsis another goal of the project.Shared whiteboards, electroniccommerce, and parallel scientific programs are some of the targeted applications.The project will lead to a better understanding of scalable, fault-tolerant distributed systems.

提案CCR-9972571TITLE：KAN：可靠的分布式对象SPI的平台：Ambuj K Singh Singh的目标是设计和实施面向对象的分布式系统，用于支持大型，复杂的平行和分布式应用程序。该系统支持具有遵循语言功能的简单但功能强大的编程模型：异步方法调用，并发线程，警卫，嵌套交易和可以透明地迁移和复制的对象。该系统通过动态运行时优化实现效率和可扩展性，例如自适应线程池，线程内部，监视对象访问模式以及动态群集和粒度。这是用于记录和恢复的低空算法的实现。对物体一致性的较弱概念进行评估，从而可以减少该项目的另一个目标之间的沟通。共享白板，电子通信和并行的科学程序是一些目标应用程序。项目将更好地理解可扩展，可扩展的，缺陷型系统的分布式系统。
