Integrating heterogeneous clusters

observations
Observations
  • Solutions exist for most needs now –
    • Certainly not all perfect yet
    • Experiment layer relatively deep
    • Plethora of workload management systems
    • Not so many for data management …
  • Service management issues starting to be addressed by some services (DPM, LFC, FTS, Gridsite, Coral)
    • But in general little thought on how site managers should manage services
  • Interoperability / interoperation
observations1
Observations
  • Workload management
    • Everyone wants pilot (aka glidein) jobs (and everyone has written a system to submit them)
  • Commonality – to reach a reliable service experiments need to systematically debug sites being used:
    • D0, CMS, dashboards, …
  • Sophisticated systems to monitor, debug, recover
    • Dirac, dashboards, grid service monitoring, etc.,
    • To improve reliability and help debug the system
