Grid computing has the potential to transform everything from
drug discovery to aerospace design to analyzing stock portfolios
but, until recently, its benefits were confined to regions where
computing infrastructure is plentiful. HP is working with
researchers in Brazil to change that --- exploring new
technologies that could bring the advantages of grid computing
to some of computing's have-nots. By hooking together individual
computers around the world, scientists have created virtual
supercomputers or grids that can quickly process vast amounts of
information, helping to produce breakthroughs in meteorology,
physics, medicine and other fields. The Brazilian effort,
relying on a software program called OurGrid, represents a
lightweight approach to grid computing. Most grids today are
composed of large organizations and new users must negotiate
entry. To join the new network, users need only download the
open source software (the latest release is OurGrid 3.0.2). By
installing and using this software, users
