2. Cal-(IT) 2 Software and Cal-IT2 Cal-IT2 will develop “living laboratories” which prototype future work, play and Internet environments Software will provide the critical “glue” which –enables system components to work together –enables applications to achieve performance The Cal-IT2 SW Environment Will … –Be completely decentralized –Target –an extraordinary diversity of HW and SW (sensors, agents, PDAs, servers, wireless and wireline networks, control rooms, …) –continuous streams of data from millions of sensors –Require “guerrilla infrastructure” which self- assembles from the bottom up –Be “Use at your own risk” –Pave the way for commercial deployment

3. Cal-(IT) 2 Cal-IT2 Applications Cal-IT2 Applications will push the envelope –Applications will process data from massive number of throwaway endpoints –E.g. traffic management, disaster response –Seti@home, Entropia applicationsSeti@home –Applications will compute based on emergent behavior of millions of self-organizing components –Think Distributed Interactive Simulation … –Applications will compute on wide variety of heterogeneous resources simultaneously –PCs, PDAs, Servers, Supercomputers, remote instruments –High-capacity networks, storage and computational resources will enable previously “big iron” applications to transition efficiently to the Grid –Grid-enabled CFD, genome@home

4. Cal-(IT) 2 Cal-IT2 Software Challenges New application paradigms –Self-organization, emergent behavior, megacomputing –Statistical approach in which some fraction of devices always non-functional New models for design, prototyping, simulation Security –Authentication of people and devices, integrity of sensor data, distributed intrusion detection, … Data –New approaches to collecting, storing, accessing and analysis of huge amounts of sensor data Scalable Grid computing –Development of large-scale campus-wide distributed testbeds –Megacomputing: Grid computing with millions of throw-away end-devices Agent-based technology –Adaptive computing, mobile agents Interfaces –Large screen “control rooms” for disaster response, ultimately a prototype for “smart offices” –Access to real-time analysis of very large datasets, visualization, multi-scale information
