Is it possible to build a High Performance Computing Beowulf Cluster using OpenStack?

How does OpenStack compare to XtreemOS?

OpenStack aims at delivering Infrastructure As A Service and while it is conceptually possible to build a HPC cluster on top of virtual machines managed by OpenStack, I believe it makes no practical sense. You can read more about OpenStack on the getting started page.

it means if i have 4 compute nodes each with 4 cores .Default cpu allocation ratio is 16 so total virtual processors will be 128 (16*16 / 2 as metioned in openstack operation guide) so openstack will not allow me to create a virtal macines with all 128 vcpu's for Higher Performance Computing ?

if no then maximum resources (cpu's and RAM) that i can assign to virtual machine equals to one compute node ?

I'm saying that since you already have the hardware available, I wouldn't waste time and resources installing openstack to run a HPC cluster on top of it: just install Beowulf on your hardware and use all of it. Or tell us more about your use case.

I think that you can use heat to build your cluster, refer to https://wiki.openstack.org/wiki/Heat/GettingStartedUsingDevstack
