Campus Bridging Workshop Reports

The cover image is based on Joachim Bering’s etching of the city of Königsberg, Prussia as of 1613 (now Kaliningrad, Russia). Seven bridges connect two islands in the Pregal River and the portions of the city on the bank. The mathematical problem of the Seven Bridges of Königsberg is to find a path through the city that crosses each bridge once and only once. Euler proved in 1736 that no solution to this problem exists or could exist. This image appears on the cover of each of the Campus Bridging Workshop reports. The goal of campus bridging is to enable the seamlessly integrated use among: a scientist or engineer’s personal cyberinfrastructure; cyberinfrastructure on the scientist’s campus; Campus Bridging cyberinfrastructure at other campuses; and cyberinfrastructure at the regional, national, and international levels; so that they all function as if they were proximate to the scientist. When Data and Networking Issues Workshop Report working within the context of a Virtual Organization (VO), the goal of campus bridging is to make the ‘virtual’ aspect of the organization irrelevant (or helpful) to the work of the VO. The April 7-8, 2010 challenges of effective bridging of campus cyberinfrastructure are real and challenging – but Indianapolis, Indiana not insolvable if the US open science and engineering research community works together with focus on the greater good of the US and the global community.

The Global Lambda Integrated Facility (GLIF) Map 2008 visualization was created by Robert Patterson of the Advanced Visualization Laboratory (AVL) at the National Center for Supercomputing Applications (NCSA) at the University of Illinois at Urbana-Champaign (UIUC), using an Earth image provided by NASA. Data was compiled by Maxine D. Brown of the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago (UIC). Funding was provided by GLIF and US National Science Foundation grants # SCI-04-38712 to NCSA/UIUC and # OCI-0441094 to EVL/UIC. The GLIF map does not represent all the world’s Research and Education optical networks, and does not show international capacity that is dedicated to production usage. The GLIF map only illustrates excess capacity that its participants are willing to share with international research teams for applications-driven and computer-system experiments, in full or in part, all or some of the time. GLIF does not provide any network services itself, and researchers should approach individual GLIF network resource providers to obtain lightpath services.

In April of 2010, Indiana University coordinated a workshop, funded in part by the National Science Foundation (NSF), on the data and networking aspects of cyberinfrastructure and campus bridging. Today’s system of national and international cyberinfrastructure is increasingly complicated and growing. We have a good deal of cyberinfrastructure available relative to data and networks nationally. What is greatly needed, and currently
