Center For Information Technology Research In The Interest Of Society

Major new initiative within the College of Engineering and on the Berkeley CampusJoint with UC Santa Cruz, UC Davis, UC Merced Over 90 faculty from 21 departmentsMany industrial partnersCITRIS will focus on IT solutions to tough, quality-of-life related problemsNever doubt that a small group of thoughtful committed citizenscan change the world. Indeed, it is the only thing that ever has.Margaret Mead

Societal-Scale Information System (SIS)A revolutionary, planetary-scale Information Utility, enabling advanced technologies to be exploited by broad communities of users.An SIS learns how it is used and adapts its functions and interfaces to user demands and the context of their activitiesIt achieves this through the provision of fluid technologies for plug-and-play component interoperation, introspection, dynamic adaptation, component self-aggregation and self-organization, and extreme personalization.Easily and naturally integrate devices, ranging from tiny sensors and actuators to hand-held information appliances, workstations, and building-sized cluster supercomputersvirtual computers Connected by short-range, unreliable wireless networks as well as by very high-bandwidth, high-latency long-haul optical backbones.Data and services must be secure, reliable, and high-performance, even if part of the system is overloaded, down, disconnected, under repair, or under attack
