The scope of work on this project is to specify, build, and demonstrate a prototype end host deployment platform consisting of three components: a) a general-purpose yet safe execution environment for experimenter code running on end hosts, b) a light-weight, programmable and customizable proxy for end hosts for redirecting end-user traffic into GENI, and c) a clearinghouse for resources contributed by end users who have opted into the system. Specific development goals include:

  1. Development of a viable end-host virtual machine
  2. Control-plane integration, including resource discovery and reservation; experiment debug and control
  3. End-user configuration and management tools
  4. Deployment strategies such as inclusion in Bit Tyrant or web plug-in
  5. End-user policy & awareness issues and mechanisms

Software Deliverables

The node manager and repy (end host vm) are in the seattle_repy.tgz tarball that can be downloaded from Install the node manager on the local machine by running ./ Note that you should have Python 2.5.2 installed (but it may work with Python 2.5.X or 2.6).

The reference implementation of a trivial experiment manager (a test client for the node manager) can be downloaded from This contains which is a trivial PLuSH / GUSH-like experiment manager.

The installer is available at

Spiral 1 Connectivity

Part of the ProtoGENI cluster.

Connectivity issues need to be sorted out (NAT traversal, intermittent connectivity, etc). End user devices will already have IP addresses. Need to figure out how they connect to clearinghouses, etc.
