远程计算是指用户在本地计算机上通过互联网利用远程超级计算机上计算资源的技术.传统的远程计算方式是用户通过telnet协议登录到远程机器上完成各项任务.这种方式在高速、稳定的网络环境下效率是很高的.但是当网络条件比较差时,如在低带宽、不稳定的网络上,这种方式会严重影响用户的工作效率.提出并实现了一个远程虚拟计算环境,它所采用的计算方式可有效完成在低带宽、不稳定的网络环境下效率较低甚至无法完成的远程计算,其中使用了如检查点设置/恢复、压缩传送、目录树传送等技术以达到尽量减少网络流量的目的.实践证明,这在我国当前的网络条件下是一种高效的远程计算方法.
Remote computing refers to the technology of computing resources on the remote supercomputer by the user on the local computer through the Internet.The traditional remote computing method is that the user logs in to the remote machine through the telnet protocol to accomplish various tasks in a high speed and stable network Environment is very efficient, but when the network conditions are poor, such as low bandwidth, unstable network, this approach will seriously affect the user’s work efficiency.Research and implementation of a remote virtual computing environment, which The calculation method can effectively accomplish the remote computing which is inefficient or even impossible in a low-bandwidth and unstable network environment, and uses techniques such as checkpoint setting / recovery, compressed transmission and directory tree transmission to minimize the network The purpose of traffic.Practice has proved that this is an efficient method of remote computing under the current network conditions in our country.
