Master-Worker on the GRID

• Parallel execution of independent tasks
• Very typical in many scientific applications

• Local cluster / remote access

• Fully distributed / remote access

4
Distributed Component Framework

• Transparent for applications
• exactly the same application code may be run in
  the cluster or GRID mode
• physical communication protocol may be
  fine-tuned transparently
• physical deployment and configuration of
  components may be changed at runtime to optimize
  access / integrate into a specific hosting
  environment
• Automatic Erorr Recovery and Control
• monitoring and live feedback
• customizable recovery policies
• Extensible application adapters
• e.g. inprocess loading (shared libs)versus IPC
  mechanisms for workers
• enhance functionality at runtime

Applications Components Geant4 example

• No changes to original application code
• no need to recode original G4 advanced examples
  to run in a distributed mode
• DIANE automatically create a suitable
  applictation component from a user library
• Efficient deployment and packaging
• shared-filesystem cluster may use common
  installation of large foundation packages via
  shared libraries example Geant 4 100 MB
• WAN distributed simulation may be linked
  statically to decrease total binaries size 9 MB
