摘　　要：为实现MPICH2的高可用,将MPICH2计算平台构建在虚拟机环境中,使得参与MPICH2运算的各个结点均是虚拟机,而物理机器并不直接作为结点参与运算;当物理机器需要进行维护、升级或负载均衡时,通过在线迁移的方式将其上运行的虚拟机迁移至另一个物理结点上,然后在新的结点上重新启动虚拟机,恢复其上运行的MPICH2计算任务,从而避免了终止整个计算任务的需要。实验结果表明,虚拟机在线迁移之后,整个MPICH2计算任务可以正确恢复;同时,比较了虚拟机和物理机器执行MPICH2计算任务的效率,表明了以虚拟机取代物理机器构建MPICH2计算平台在性能上是可行的。To achieve high availability of MPICH2,build the MPICH2 computing platform into the environment of virtual machines so that all the nodes that participate in the MPICH2 computing are virtual machines while the physical nodes don’t participate in the com-puting directly.When one physical node needs to be maintained,upgraded or make load balancing,we could transfer the virtual machine that runs on it to another physical node using live migration,then restart the virtual machine on the new node and resume the MPCH2 computing task so that we could avoid the need to terminate the entire computing task.By experiment and tests,prove that the entire MPICH2 computing task could resume correctly after live migration of the virtual machine.And,prove that using virtual machines instead of physical machines to construct the MPICH2 computing platform is feasible in performance by comparing the efficiency of executing MPICH2 computing task in virtual machines and physical machines.
