[Beowulf] Docker in HPC

[Joe Landman]

I know there was some discussion of this previously, and I wanted to 
point out this update

http://blog.docker.io/2013/11/docker-0-7-docker-now-runs-on-any-linux-distribution/

Interesting that the AUFS dependence is now not blocking things.

Hopefully I'll get a chance to play with it in a few weeks in an HPC 
context, to see what the container performance cost is (if anything). 
Hopefully quite low.

If someone has already done this, please post a link.

This is an OS level virtual system.  Not a hypervisor, or a paravisor, 
so it *should*, in theory, be lower latency.  It looks like we can 
generate Docker files trivially from a machine specification in Tiburon, 
though we are very JSON centric these days.
