The VCG Workgroup The VCG Workgroup

  • Development and deployment of a high-

performance computing service based (to some extent) on the Globus middleware, providing:

– A distributed task execution environment that employs

resources from machines connected to the RNP backbone

– The simplest possible access to such resources (Web)

  • Basic features:

– Bartering-based economy model (self-recharging tbi)

  • Centered around user projects

– Automatic management of certificates – Integrated monitoring (resources, security...)

Challenges Challenges

  • Porting applications: the hemogrid case
  • Virtualization: not really a problem (more of a

solution!)

  • Putting it all together: workflows in Globus 4 WS,

MPI applications (both manually, centrally- and self- scheduled) in Globus 4 pre-WS, ...

  • Globus unfriendliness with firewall & NAT:
  • ngoing work on developing/deploying overlays
  • Resource differentiation: user-shared X grid-

dedicated, project-shared X project-exclusive, ...

  • Integrated certification & federation: Shibboleth

Opportunities Opportunities

  • Interoperation/co-existence with different grids:

OurGrid, EELA-2, SINAPAD,...

  • Virtualization: as I said...
  • More “sinergy” with RNP resources: PoP

servers, classrooms (ESR)

  • Cloud computing: grid sustainability
  • Virtual communities: despite the workgroup

name...
