based architecture to create layered approach to enabling scalable fault tolerance. The This project will focus on the middleware layer used to provide message passing capabilities for distributed memory applications. The system will use a component-design and implementation of the message passing system will provide sufficient flexibility to accommodate a wide variety of application state management and recovery mechanisms. The proposed message passing system will have the following capabilities.o Failure detection;o Fault tolerance of the run-time system;o Fault tolerance of the message passing layer (MPI);o Meaningful semantics for the message passing layer in the presence of faults;o Flexible application interface for fault notification; ando Support for application state management and recovery.This work will be realized as part of the component framework of LAM/MPI, an existing high-quality implementation of the Message Passing Interface standard.This project will have broader impacts in several areas. Availability of a scalable and reliable middleware layer will enable new levels of application scalability. In addition, new capabilities for MPI jobs can be realized, including process migration, non-stop behavior, and gang scheduling. Since the proposed middleware will be realized in the context of MPI, applications written with MPI can immediately benefit from this work.And, since the work will be integrated into a production-quality implementation of MPI, the results can actually be used by a widespread audience. The modular component-based design of our implementation will allow the middleware to be used by a wide variety of state management and application-specific fault tolerance schemes. Finally, important contributions from this work are in the form of interface designs-other implementations of MPI will also be able to adopt these approaches to provide reliability

的体系结构来创建分层方法，以实现可扩展的容错能力。这个项目将集中在用于为分布式内存应用程序提供消息传递功能的中间件层。该系统将使用组件设计，消息传递系统的实现将提供足够的灵活性，以适应各种各样的应用程序状态管理和恢复机制。o故障侦测;o运行时系统的容错能力;o消息传递层的容错能力;o消息传递层在出现故障时的有意义语义;o灵活的应用程序界面，以供故障通知;支持应用程序状态管理和恢复。这项工作将作为LAM/MPI组件框架的一部分实现，消息传递接口标准的一个现有的高质量实现。这个项目将在几个领域产生更广泛的影响。可伸缩和可靠的中间件层的可用性将使应用程序的可伸缩性达到新的水平。此外，还可以实现MPI作业的新功能，包括进程迁移、不间断行为和群组调度。由于所提出的中间件将在MPI的上下文中实现，因此使用MPI编写的应用程序可以立即受益于这项工作。而且，由于这项工作将集成到MPI的生产质量实现中，因此结果实际上可以被广泛使用。我们的实现模块化的基于组件的设计将允许中间件被用于各种各样的状态管理和应用程序特定的容错方案。最后，这项工作的重要贡献体现在接口设计方面--MPI的其他实现也将能够采用这些方法来提供可靠性
