Dr Larry Smarr is the director of the National Centre for Supercomputing Applications (NCSA) at Champaign, Illinois. The most powerful concept to have emerged from NCSA is that of 'metacomputing': the combination of supercomputers and America's planned digital superhighway. This will enable any user to remotely access supercomputers and visualisation programs from their own desk-top workstations. Processing can be split and done by different computers simultaneously, enabling the processing of vast amounts of data at incredible speeds. Smarr believes that the new technologies emerging from NCSA will shape the electronic society of the 21st Century.
