3. D0SAR - September 2005 Andre Sznajder 3 2001- Presentation of a New Project to FINEP Aproved 500 machines: But... Dollar increase 3x could buy only 100 machines. 2002- The first part of the financial support delivered. Bureaucracy delays our projects about 2 years Need to create infrastructure. Link provided by REDE RIO at 2 Mbps 2003- Start to buy the machines and build the group2003- Start to buy the machines and build the group CALTECH group has been very helpful – Many Thanks ! 2004- Hepgrid and Digital Divide Workshop at UERJ2004- Hepgrid and Digital Divide Workshop at UERJ, See http://www.lishep.uerj.br/ December 20th. inauguration of UERJ HEPGRID cluster HEPGRID Historic
