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 )

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
