This workshop gives attendees hands-on experience to understand and debug network issues using single-board computers running open-source network measurement tools. The computers will be connected as a local-area network (LAN) while emulating a wide-area network (WAN). The attendees also will learn about the characteristics of WANs – delays and packet losses – and how they affect the overall performance of the network and, in turn, data transfers to and from HPC sites. Participants also will be exposed to various host-level settings they can tune to improve performance. Attendees will learn to speak the language of network engineers and know what to share in a trouble ticket to help network engineers debug their performance issues.<br />
This technical workshop is relevant to graduate computer science students and those who work in or are interested in ICT (and/or those who want to work with Raspberry Pis). The workshop requires intermediate skills in computer science and a basic understanding of Linux/UNIX, TCP/IP packets and networks. The session will be limited to roughly 40 attendees.
