CGL: Community GridsLaboratory

Geoffrey Fox

Director CGLProfessor of Computer Science, Informatics, Physics

Community Grids Laboratory Established July 2001 as one of IU Pervasive

Technology Laboratories, funded by Lilly Endowment Located in IU Research Park (Showers) Bloomington 5 Research Associates 1 Professional Staff 27 PhD candidates plus 3 obtained PhD during

Summer 4 Temporary employees (consultants, students in

transition after PhD)

Guiding Principles e-Business and e-Science imply global virtual

communities Grids are enabling infrastructure for virtual

organizations Computers are so fast that can use new and more

transparent architectures and protocols Need to understand mix of open source, “university

proprietary” and commercial software Globalized workforce (Outsourcing) will give us

challenges and opportunities in both New Community Grid tools needed Who will write our software
