Comments on: HPC Virtualization Fun http://www.linux-mag.com/id/4180/ Open Source, Open Standards Sat, 05 Oct 2013 13:48:18 +0000 hourly 1 http://wordpress.org/?v=3.1 By: rgb@phy.duke.edu http://www.linux-mag.com/id/4180/#comment-4744 rgb@phy.duke.edu Wed, 30 Nov -0001 00:00:00 +0000 http://www.linux-mag.com/id/4180/#comment-4744 Interesting article (given that there is an ongoing beowulf list discussion of this very issue). I think it might be useful, however, for LM to come up with a very technical issue on virtualization. There's hardware support now, so they say. What does that mean? How does it work? What is KVM and how does it support it or exploit it? What are the prospects for a beowulf-specific KVM hack that allows the creation of portable checkpointable migratable mini-VMs for doing specific HPC computations without the jitter or overhead associated with full-scale virtualization? Is there any way to create "symmetric VMs" or is a VM necessarily a host/guest kind of thing.<br /> <br /> rgb Interesting article (given that there is an ongoing beowulf list discussion of this very issue).
