Research on Virtualization Technology Application in Desktop Grid Environment
摘要
Abstract
Desktop grid is a heterogeneous computing resource environment,which challenges the cross platform application deployment and heterogeneous resource integration.With good encapsulation and isolation,virtualization technology is used for integrating heterogeneous resources and shielding the difference of different platforms.Hence,a desktop grid system is implemented based on VirtualBox Virtnal Machine(VM).After testing different configuration parameters of VM,self-adaptive memory allocation module is designed.And based on the different stages of job operation,analysis of the influence on job operation caused by different performance of hard disk I/O and bandwidth I/O is given.According to the analysis result,VM image diversity and the performance loss caused by virtual machine start-up and bandwidth,the remote image library and dyamic job file system are designed,which meet the diverse requirement of VM image and quick deployment of job running environment.Meanwhile,cache service is used to make up for the loss caused by the use of VM.Application results show that this virtual desktop grid system can meet the needs of high energy physics computing very well.关键词
