Sažetak
Over recent years we have seen a constant evolution of High-Performance Computing moving into commodity servers cluster types of systems. At the same time we have seen Cloud Computing being a proven, stable and reliable IT paradigm, utilising virtualized clusters of commodity servers as key components. This paper presents a face-to-face native-to-virtual HPC MPI application performance analysis on a range of general-use HPC applications by virtualizing InfiniBand via IPoIB at the guest virtual machine level on VMware ESXi as well as KVM hypervisor with production ready live migration support. Applications running on various small and medium HPC clusters are targeted to address users, considering full IT infrastructure virtualization by merging general purpose with HPC IT infrastructure. Live migration is a key component within a virtualized environment as it enables dynamic virtual IT infrastructure, therefore live migration performance impact is evaluated through a pluggable multi-platform architecture on a proactive fault-tolerance use case.
