ＣｈａＲＭ是一种并行程序后向故障恢复与进程迁移系统．它不仅实现了对工作站机群系统瞬时故障的恢复，而且通过检查点设置时的Ｍｉｒｏｒ存储技术和进程迁移技术，实现了对机群系统结点永久故障的恢复，并支持系统软硬件的在线维护、处理机资源的排他／限时使用和动态负载平衡等功能．文章主要介绍ＣｈａＲＭ系统的检查点设置与回卷恢复、进程迁移等实现技术，并给出了部分性能评测结果． ChaRM is a parallel program post-fault recovery and process migration system. It not only realizes the recovery of instant failure of workstations and fleet systems, but also realizes the restoration of permanent faults of cluster system nodes through the Miror storage technology and process migration technology of checkpointing, and supports the online maintenance and processing of system hardware and software Exclusive / limited use of machine resources, and dynamic load balancing. This article mainly introduces ChaRM system checkpoint setting and rollback recovery, process migration and other implementation techniques, and gives some performance evaluation results.
