Although multi-site MPI execution has been criticized in the past as being "Impractical" due to limitations in network latency and bandwidth, the authors believe many of the obstacles can be overcome by various means for wider classes of applications than previously believed. The current work involves using Xen as the underlying virtual machine layer to implement such migration, along with performance-optimizing migration strategies - this particular paper deals with performance evaluations of MPI on Xen VMs including what are the possible performance hindrances, implications of migrations, as well as the effect of variations in latencies and bandwidth parameters as realized by the overlay network using a software network emulator.
