Memory Management Issues in Large Scale Shared Memory MIMD Multiprocessors.

在紧耦合的MIMD机器中管理各级共享存储的操作系统机制和策略的研究处于早期阶段。对于拥有数百个处理器的大型机器来说，情况更是如此。该项目将继续对大规模案件中的这些问题进行多年调查，重点是蝴蝶多处理器。具体项目分为以下类别：工作负载表征、跨并行主存储器的共享数据迁移、在每个与主存储器相关联的多个辅助存储器的设置中管理虚拟存储器，以及文件系统设计。

The study of operating system mechanisms and policies for the management of various levels of shared storage in tightly-coupled MIMD machines is at an early stage. This is even more true for the case of large-scale machines with hundreds of processors. This project will continue a multiyear investigation of these issues in the large-scale case with a focus on the Butterfly multiprocessor. Specific projects divide into the following classes: workload characterization, shared data migration across parallel main memories, management of virtual memory in a setting of multiple secondary memories each associated with a main memory, and file system design.
