16. 16 - OneLab - AsiaFi– November 17, 2009 – AIT Bangkok Terminology ● Site A: site is a physical location where PlanetLab nodes are located (e.g. Fraunhofer Institute or UCL). ● Node A: node is a dedicated server that runs components of PlanetLab services. ● Slice A: slice is a set of allocated resources distributed across PlanetLab. Slices are assigned to some number of PlanetLab nodes. Slices have a finite lifetime and must be periodically renewed to remain valid. ● Sliver A: sliver is a slice running on a specific node. You can use ssh to login to a sliver on a specific node.

70. 70 - OneLab - AsiaFi– November 17, 2009 – AIT Bangkok Deploying to a sliver scp -l huji_dimes \ -i ~/.ssh/id_rsa -r \ localdir evgsics7.sics.se: Copy localdir to the remote machine rsync -a -e “ssh -l huji_dimes” \ localdir evgsics7.sics.se: Update the remote directory. Copies only those files that are different

71. 71 - OneLab - AsiaFi– November 17, 2009 – AIT Bangkok Deploying Software to Your Nodes ● Copy binaries to the node to run – scp or rsync works for small numbers of nodes – Ensure library dependencies are satisfied
