We performed some benchmark testing with linpack and bonnie++ on the VM and on the physical host. For para-virtualized VMs, the linpack performance is on par with the physical host. However, for bonnie++ tests, para-virtualized VMs fell way behind physical host's performance. In short, CPU-bound and memory intensive HPC apps should do ok but not IO-intensive apps. More testing and fine-tuning will probably be needed to see how far we can push the VM in terms of IO-intensive operations but we are hoping that in time to come virtualization technologies will be able to narrow that gap. And yes, the VMC application is open source. You can find the download links in the VMC Install document.
