Benito

Benito is a containerized approach to a next-gen testbed.

• August 2011 Demo Milestones

Embedder

• Spits out annotated TopDL
• Dumb (static)
• Smart
  • Linear optimization problem (faber)
• Self-describing containers guide embedding process

Standard Container Interface

Need to merge the current Benito and fedd views on the standard interface

Needs a query interface, support for:

• day-to-day experiment operations (node status, etc.)
• recursive querying into internal containers
• information to guide embedder

A smart embedder will query the pnode HV(s) for node availability and embed based on that. If the assign process on a pnode HV fails for some reason (e.g., someone swapped in a large experiment in the meantime), the embedder will requery and re-embed. This works given that swapins are a relatively rare event.
