Thoughts on how to create virtual compute nodes in the HPCC stack. Specifically, trying to solve the need for tiny, but many, compute nodes for the nano physic applications. Like virtual compute nodes with a single core CPU with 100 MB or less of memory running a lean Scientific Linux operating system. Here is a good introduction: http://www.slideshare.net/gpaterno1/comparing-iaas-vmware-vs-openstack-vs-googles-ganeti-28016375
I'll select Ganeti to start with as it appears the simplest to setup. I've no need for services like fail-over or migration. Just the ability to rapidly many tiny nodes from a template. It also appears that Ganeti clusters can be embedded with Openstack later.
On hold, these Xen tools are very nice, no need for Ganeti up front (virt-manager, virt-clone, virsh).
To come.
