Despite of Cloud infrastructures can be used as High Performance Computing (HPC) platforms, many issues from virtualization overhead had kept them unrelated. However, with advent of container-based virtualizers, this scenario acquires new perspectives because this technique promises to decrease the virtualization overhead, achieving a near-native performance. In this work, we analyzed the performance of a container-based virtualization solution - Linux Container (LXC) - against a hyper visor-based virtualization solution - KVM - under HPC activities. For our experiments, we considered CPU and communication (network and inter-process communication), and results showed the virtualizer type can impact distinctly in performance according to resource used by application.
