远程高性能计算环境的设计与实现技术

Remote high performance computing environment for low reliability networks

Ri CE(remote high computing environm ent)系统旨在建立以高性能并行计算机为计算资源的远程计算环境。系统合理划分本地机和远端机的工作任务 ,引入增量更新、压缩传送、检查点设置和恢复等多种传输措施 ,并集成了负载平衡工具 ,提供了身份检查、日志记录等安全机制 ,改变了传统的 Telnet工作模式。具有联网、远程执行过程对用户透明、系统安全性好和适应我国低带宽、实时性差、可靠性低的网络现状的特点。用户可以以较低的成本方便地使用远程计算机系统 ,从而充分发挥高性能计算机的性能。 Ri CE系统目前已在曙光 2 0 0 0和 IBM SP2等系统上运行通过 ,表明该系统性能良好 。

The RiCE project (remote high performance computing environment) seeks to establish a remote computing environment based on a high performance parallel computer. RiCE effectively partitions the tasks of the local and remote machine using various transfer mechanisms, including incremental updates, compressed file transfer, checkpointing and recovery. The system also uses a load balance tool and security mechanisms, such as user authorization and logging. Therefore, RiCE provides a remote system that can be used with the low bandwidth and poor reliability of Chinese networks.
