GRID vs. MPI vs. TANGO/TACO

• Distributed also means parallel

• What technology to use ?

• • GRID e.g. GLOBUS toolkit
  • Message Passing Interface (MPI)
  • TANGO/TACO device servers

• Pros and Cons

• • GRID too complicated for a small project
  • MPI a possibility but almost the same as ...
  • TANGO/TACO has most of the features of MPI
  • • it enables us to do scripting
    • on-line state machine querying
    • we understand TACO/TANGO better
