In view of the new scientific programs established for the LHC (Large Hadron Collider) era, the way to face the technological challenges in computing was develop a new concept of GRID [1, 2] computing. We show some examples and, in particular, a proposal for high energy physicists in countries like Brazil. Due to the big amount of data and the need of close collaboration it will be impossible to work in research centers and universities very far from Fermilab or CERN unless a GRID architecture is built. An important effort is being made by the international community to up to date their computing infrastructure and networks. © 2003 American Institute of Physics
