  1. Installation and Integration of Virtual Clusters onto Pragma Grid NAIST Nara, Japan Kevin Lam 06/28/13

  2. Overview • Grid computation has been used over the years to run large tests that would otherwise take a long period of time to complete. • However, because each physical cluster (group of computers acting as a single unit) differed from the next, the results were inconsistent. • Previous studies have shown that virtual machines (software version of a single computer) grouped into a virtual cluster would provide much more consistent results. • By integrating the virtual cluster onto the pragma cloud, tasks such as virtual screening would be more efficient and have better results.

  3. Week 1: Installation of OS and Creation of Virtual Machines • Installation of Debian OS and Xen Hypervisor onto a laptop was done allowing for multiple OS synchronicity. Later, the realization was that the laptop would not support larger amounts of operating systems. • Kernel-based Virtual Machine (KVM) seemed to be a better alternative to Xen. The architecture is more straight forward. • Installation of CentOS 6, which has native KVM support, onto a different computer was done. • Four virtual machines with CentOS 6 were created. Bridging and network configurations were set. • SSH server and clients were installed on the host and nodes. It is now possible to SSH from the host to nodes without passwords or IP-addresses. • Open MPI was installed and configured for the cluster.

  4. Future: Near and Nearer • A machine file needs to be created for the MPI to recognize each node. • Dock needs to be installed onto each virtual machine and configured so that it works for the cluster. • Test runs need to be done in order to verify the clusters performance. • We should look more into integrating our virtual cluster with NAIST’s cluster, PRAGMA cloud, and, possibly, Amazon E2.
