Resource Management Challenges introduced by the GRID

• Site Autonomy

• Heteregenous Resources and Substrate
  • Each site has systems with different architectures (SMPs, Clusters.Linux/NT/Unix./Intel)
  • each resource owners have their own policies or scheduling mechanisms (Codine/Condor).

• Policity Extensibility (through resource brokers)

• Resource Allocation/Coallocation

• Online Control (can Apps (Graphics) tolerate nonavailablity of required resource and adapt itself)

• Computational Economy
