School of Information Technology University of Pretoria Our vision - Communication  Between computers and computers  Between computers and people  With each other and our colleagues  With overseas and industrial collaborators

School of Information Technology University of Pretoria Success to date - Science  Java web skeleton –spin-off company and for the International AIDS Conference in 2002 (with TU-Berlin and E-Volution)  Views system –first Microsoft competitive RFP grant 2002 –began research in GUIs, XML extension, reflection, and interoperability  RoSCtor –Software construction in Rotor, emphasising new programming techniques such as aspect-oriented development (Microsoft)  –industry-related research in service-based architectures, and product line practice (Microsoft, Jay van Zyl – SystemLogic and Dirk Muthig, Fraunhofer Kaiserslautern)  Linca –Cryptographic skeleton for mobile phones

School of Information Technology University of Pretoria Success - Service  Java Gently and C# Concisely –support for readers worldwide: exercises, answers, quizzes and websites, also new language investigation e.g. Spec# (Microsoft)  Component Deployment 2002, 2004, 2005 –Initiated and assisted with these conferences  Reviewing for 7 major conferences annually  ACM Software System Award –nominated James Gosling for Java –now chairman of the award ( )  Scholarships –DAAD - Judith Bishop to TU Berlin 2003 –University - Kathrin Berg to F’H Kaiserslautern 2005 –Scarce Skills - Basil Worrall –Humboldt - Kurt Geihs, from U Kassel 2006

School of Information Technology University of Pretoria Current collaborative projects  Algon –a framework for distributed algorithm interchange (Karen Renaud, Univ. Glasgow)  Views 2.0 –an XML-based GUI engine for platform interoperability (Nigel Horspool, Univ. Victoria and Microsoft Research)  Cosmos –the composition and monitoring of services in unstable and evolving contexts (Carlo Ghezzi, Politecnico di Milano)  Nomad –a distributed information sharing system for casually connected communities (Microsoft, Albie von Gordon, E-Logics)  Algon-P –applying Algon framework to parallel algorithms (ELogics)

School of Information Technology University of Pretoria  Framework for interchangeable distributed algorithms  Can also interchange middlewares e.g RMI to Corba  Includes a performance monitoring display  Used for mutual exclusion, deadlock, termination  Now adapting it to parallel algorithms for use in supply chain management 1.
