The ReSS Project

• Goal Provide a Cluster-level Resource Selection
  Service Integrating Off-the-shelf Technologies
• Stakeholders
• DZero, DES, OSG Engagement
• Fermigrid
• OSG
• Budgeted FTE
• 0.3 FTE for FY08
• Gabriele and Tanya

ReSS Pushing Jobs to Sites

• Users express cluster requirements in the JDL
• Jobs sit in the site batch system queue until
  execution
• ReSS can be queried and info passed to VO

Concerns

• Deployment of CEMon in OSG v1.0.0 how many
  months will we have to cope with 2 info schemas
  from sites?
• GIP problems show up as CEMon problems.
  Understanding how to allow sites to self-detect
  the difference.
• Better integration of ReSS with Glidein WMS
