ExoGENI/GIMI Tutorial

Overview:

The objective of this tutorial is to introduce the GIMI tool set to experimenters who are interested in performing experiments on ExoGENI slices. We will introduce an experiment workflow which experimenters will most likely apply to perform measurements.

After the tutorial, experimenters should be able to:

• Create a slice on ExoGENI and run an experiment on top of this slice.
• Orchestrate experiments with OMF:
  • Set up routing on top of topology
  • Verify that topology has been set up correctly
  • Execute an experiment that measures the impact of packet size on throughput by comparing udp output at the sender and udp input at the receiver.
• Store and retrieve data to/from iRODS
• Analyze/visualize measurement data with various tools
