KVM and Xen use iterative pre-copy approaches=0Awhich work well in practice for commercial applications. In this paper,=0Awe study pre-copy live migration of MPI and OpenMP scientific=0Aapplications running on KVM and present a detailed performance=0Aanalysis of the migration process. We show=0Athat due to a high rate of memory changes, the current KVM rate control=0Aand target downtime heuristics do not cope well with HPC=0Aapplications: statically choosing rate limits and downtimes is=0Ainfeasible and current mechanisms sometimes provide sub-optimal performance. We=0Apresent a novel on-line algorithm able to provide minimal downtime and=0Aminimal impact on end-to-end application performance. At the core of=0Athis algorithm is controlling migration based on the application=0Amemory rate of change.
