PetaSIM Basic Components

• We define an object structure for resources (computer, I/O, network) and data

  • These object representations can also be used in dynamic tools in areas of scheduling (eg. Condor, Legion or Globus) and seamless interfaces (eg. UNICORE, WebSubmit, SWeb) as well as other performance projects (especially POEMS and Warwick)
  • Java Grande Forum will propose a “community standard compute resource” object structure as part of “Java Framework for Computation”

• Architecture Description

  • nodeset & linkset
  • (describe the memory hierarchy of architecture)

• Data Description

  • dataset & distribution (not stressed in current state of development)

• Application Description

  • execution script (needs further refinement)
