HEP Computing in Rio

• 1982 Begining of Experimental HEP activities
• 1983 - ACP1 ( paralelization software CPS )
• 1985 - ACP2 ( hardware board design , software
  OS )
• 1995 CHEP 95 in Rio ( first international VC in
  Brazil )
• 1997 Client/Server project with IBM(Grid
  Precursor )
• Client/Server Upgrade GRID

HEPGRID Historic

• 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
  group
• CALTECH group has been very
  helpful Many Thanks !
• 2004- Hepgrid and Digital Divide Workshop at
  UERJ,
• See http//www.lishep.uerj.br/
• December 20th. inauguration of UERJ HEPGRID
  cluster

Rio 2005 CMS GRID Meeting

• Main outcomes
• Decision to connect HEPGRID to Fermilab T1
• Grid3/OSG installation certification
• Start CMS Monte Carlo production
• RNP decided to provide cluster connectivity
• (Currently 100Mbps , but will be upgraded to
  1Gbps exclusive
• after September 2005)

National Research and Education Network (RNP)

• Maintained by the Brazilian government
• Provides national (inter-state) and international
  connectivity for more than 200 universities and
  research centers
• collaboration links to other similar networks
  internationally (Internet2, GÉANT, APAN,
  RedCLARA)
• supports the development of advanced networking
  and its applications

Perspectives

• Install SAMGRID and begin P17 reprocessing MC
  production for D0
• Install dCache for CMS digi/reconstruction
• Storage upgrade to 200TB
• Cluster upgrade ( rack mounted ? )
