Task Reconfiguration Problems in High-Performance Distributed-Memory Machines

拟议的研究涉及探索技术， 分布式存储器机器上的任务模块的重新配置， 故障发生。 这些问题包括：（1）地方之间的权衡 （2）通信需要支持 恢复成功后的重构和任务计算; 容错嵌入;（4）残差结构分析 网络中存在故障节点，（5）广泛的 故障模式仿真和算法性能 在Paralex 10维超立方体上开发的

The proposed research concerns the exploration of techniques for reconfiguration of task modules on distributed-memory machines when faults occur. The problems include (1) trade offs between local and global reconfiguration; (2) communications required to support reconfiguration and task computation after successful recovery; (3) fault-tolerant embedding; (4) analysis of the residual structure of networks in the presence of faulty nodes, and (5) extensive simulations of fault patterns and the performance of algorithms developed on a Paralex 10-dimensional hypercube.
