2.  A new tool available to GENI researchers for managing experiments ◦ Standalone desktop application, runs on Linux and Mac OS X  Works with any aggregate that supports the GENI AM API and uses GENI RSpecs  “Plugin” architecture makes it easy to add new management and monitoring services ◦ Example: Raven package management service

3.  Use Sface to: ◦ Discover available resources ◦ Add and remove resources from a slice  Use Raven to: ◦ Package an experiment ◦ Deploy it into a slice ◦ Monitor the experiment

4.  Slice ◦ A network of communication and computing resources capable of running an experiment or a wide-area network service  Component ◦ On PlanetLab, an edge computer (a “node”)  Sliver ◦ A virtual machine running on a component  Aggregate ◦ A group of components (e.g., a testbed) http://groups.geni.net/geni/wiki/GeniGlossary

5.  Guest1-30 accounts on PlanetLab ◦ Password: geni  Login to the account assigned to you  Run “sface”

6.  Installing Sface (we’ve done this for you) ◦ Download packages, dependencies ◦ Put private key in ~/.sfi/  On Configuration screen ◦ User HRN: plc.gec11.guestXX ◦ Slice HRN: plc.gec11.sliceXX ◦ User’s authority HRN: plc.gec11 ◦ Click “Apply & Save”

7.  Go to Main Window ◦ Click “Update Slice Data” ◦ Wait ~1 minute  See a list of aggregates with summaries  Expand to list all of the aggregate’s nodes ◦ Some nodes may not be working…  At this point, the slice should not have slivers running on any nodes

8.  Generate and submit request for resources  Double-click on a node to add it to the slice ◦ Requests a sliver on that node  Type a string in the search box to only show nodes containing that string ◦ E.g., “princeton”  Pick a few nodes from PLC, PLE, and/or VINI and click “Submit”

9.  Double-click on a blue node to remove it from the slice  Now, remove all nodes from your slice  Click “Submit”  Should see empty summaries

10.  Add PlanetLab-specific tags to slivers ◦ Right-click on “Default tags for XYZ” to add attribute to all slivers on aggregate XYZ ◦ Right-click on a node to add attribute to the corresponding sliver ◦ Choose attribute from pull-down, type value  Add “initscript” attribute with value “stork” to all PLC nodes ◦ Downloads and runs the “stork” script when the VM starts

11.  Default tag on PLC: initscript/stork  Add ~20 PLC nodes to your slice  Click “Submit”  Verify that nodes, tag were added to slice  Now… wait 15 minutes for slivers to be created

12.  Wiki page (with download links): ◦ http://svn.planet-lab.org/wiki/SfaceGuide http://svn.planet-lab.org/wiki/SfaceGuide  Google Group: ◦ http://groups.google.com/group/sface-users/ http://groups.google.com/group/sface-users/

13.  Goal: each slice has 20-30 working nodes for the Gush tutorial next…
