Title:  Slicing with SHARP: An Architecture for Secure Resource Peering

Abstract:

  This talk will introduce SHARP, a framework for secure distributed
  resource management in a utility computing infrastructure or grid.  We
  designed SHARP as an extensible foundation for a resource sharing
  economy, with accountability for resource sharing agreements and
  assurances for predictable performance (e.g., resource reservations
  and Service Level Agreements).

  The cornerstone of SHARP is a mechanism to define cryptographically
  protected contracts (claims or leases) to control bundles (slices) of
  raw resources over designated time intervals.  SHARP also defines
  secure primitives to subdivide and delegate claims across a network of
  resource managers.  SHARP resource claims have a configurable degree
  of assurance spanning a continuum from hard reservations to hints for
  resource discovery.  SHARP reconciles coordinated resource management
  across the system with site autonomy and local control over resources.

  After outlining the core SHARP primitives and the mechanisms
  underlying accountable claim delegation, the talk will explore its
  role in framing architectural and policy choices for federated
  utilities and grids.  I will survey the space of structures for
  resource management and trust management that may be realized using
  SHARP, and report some experience with a prototype on the PlanetLab
  testbed and work in progress in the Cluster-on-Demand project (COD).
