7. Sponsored by the National Science Foundation 7 GREE SC: June 24, 2013 The GENI Portal is… A web-based tool for experimenters to manage experimenters, projects, and slices. Includes simple tools to reserve resources. More to come in the future.

8. Sponsored by the National Science Foundation 8 GREE SC: June 24, 2013 Experimenter An experimenter is a researcher who uses GENI resources Different types of experimenters have different roles and permissions: Advisor vs Grad Student Teacher vs TA vs Student Experimenter

9. Sponsored by the National Science Foundation 9 GREE SC: June 24, 2013 Projects Projects organize research in GENI Project Lead Members Slice Projects contain both people and their experiments A project is led by a single responsible individual: the project lead

10. Sponsored by the National Science Foundation 10 GREE SC: June 24, 2013 Creating Projects Only project leads can create projects. Project names are public, unique and permanent A project may contain many experimenters; an experimenter may be a member of many projects Projects have an optional expiration (e.g. for classes, tutorials) For today’s tutorial we will all join a project which expires in a week

14. Sponsored by the National Science Foundation 14 GREE SC: June 24, 2013 InCommon For many experimenters: no new passwords familiar login screens Leverage InCommon for single sign-on authentication Experimenters from 304 educational and research institutions have InCommon accounts

15. Sponsored by the National Science Foundation 15 GREE SC: June 24, 2013 Using ssh with a public/private keypair Login to all GENI compute resources using ssh with a private key There are several ways to offer your private key to ssh. Today we will use tool called an ssh agent. $ ssh-add ~/.ssh/id_geni_ssh_rsa $ ssh username@hostname -p 12345 You should never be prompted for a password to log into a GENI compute node. If you are, something has always gone wrong. No password!

20. Sponsored by the National Science Foundation 20 GREE SC: June 24, 2013 Resource A resource is a piece of infrastructure A resource can be real or virtual. Resource specifications are used to describe and request resources. Examples: Compute: computer vs virtual machine (VM) Wireline Network: VLAN or OpenFlow Wireless: WiMAX

21. Sponsored by the National Science Foundation 21 GREE SC: June 24, 2013 Aggregate An aggregate manages a set of reservable resources Aggregates include: GENI racks OpenFlow WiMAX InstaGENI RackExoGENI Rack

22. Sponsored by the National Science Foundation 22 GREE SC: June 24, 2013 Slice A slice is a container of resources used in an experiment. A slice can contain resources from one or more aggregates A slice is in a single project A slice has an expiration Slice names are public, reusable and unique

24. Sponsored by the National Science Foundation 24 GREE SC: June 24, 2013 Expiration and renewal slice expiration time ≤ project expiration time each resource expiration time ≤ slice expiration time each resource expiration time ≤ aggregate’s max expiration project slice resource (optional) project expiration time slice expiration time resource expiration time now In general, to extend the lifetime of your resource reservation, you must renew the slice and all resources resource

25. Sponsored by the National Science Foundation 25 GREE SC: June 24, 2013 Slice Membership Membership in a slice controls: –who can act on a slice, and –sometimes who can login to the resources on a slice. You can only add other members of your project to your slice Project leads are added to each slice by default Slice members will be able to login to resources reserved in the future if: –the resources were reserved directly through the portal (by clicking Add Resources on the slice page), and –the slice member has uploaded an ssh public key.
