Kan: A Platform for Reliable Distributed Objects

提案CCR-9972571标题：Kan：可靠分布式对象平台PI：Ambuj K Singh该项目的目标是设计和实现分布式面向对象系统，以支持大型复杂的并行和分布式应用程序。该系统支持一个简单但功能强大的编程模型，具有以下语言特性：异步方法调用，并发线程，保护，嵌套事务以及可以透明迁移和复制的对象。该系统通过自适应线程池、线程内联、对象访问模式监控、动态聚类和粒度等动态运行时优化来实现效率和可扩展性。这是通过低开销的日志记录和恢复算法实现的。研究允许减少处理器之间通信的对象一致性的较弱概念是该项目的另一个目标。共享白板，电子商务和并行科学程序是一些目标应用。该项目将导致更好地理解可扩展的，容错的分布式系统。

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.
