Using Xen Virtualization Environment for Development and Testing of Supercomputing and High Performance Computing (HPC) Cluster MPICH2 MPI-2 Applications
Dear All, I have created a virtual high performance computing (HPC) cluster of 6 compute nodes with MPICH2 using Xen-based Fedora 11 Linux 64-bit paravirtualized (PV) domU guests. Dom0 is Fedora 11 Linux 64-bit. My Intel Desktop Board DQ45CB has a single onboard Gigabit LAN network adapter. I am able to bring up the ring of mpd on the set of 6 compute nodes. However, I am consistently

How to Backup and Restore MBR within Logical Volumes?
Hi All, I have several Xen virtual machines within logical volumes using LVM2. I did not use disk images for performance reasons. Conventionally, if I want to clone my virtual machines, I have to dd the LV to an image file. But this consumes a lot of time and harddisk space. So, instead of doing that, I want to use losetup and kpartx with my logical volumes, which contain operating systems of
