Scenario of Computational Pathway Elicitation for
Year 2

Year 2 Scenario Proposal

• Simple scenario illustrates an interface to allow
  users to define computational pathways
• Behind the scenes, DOCKER uses descriptions of
  components and their constraints (developed in
  Year 1) to
• detect errors in users input
• suggest additional steps needed to make the
  pathway work
• make educated guesses about how components
  selected by the user may be connected to one
  another

User is Done Defining Pathway, System is Aware of
Additional Requirements

• System knows to setup a loop to iterate IMR over
  Eqks in EFM (by setting up a set reformulation)
• System knows to ask for a span (needed to setup
  EFM Step) that the user did not mention
• System generates details required to run on the
  Grid

20
New Capabilities

• System uses descriptions of components and their
  constraints (available in DOCKER) to
• detect errors in users input
• suggest additional steps needed to make the
  pathway work
• make educated guesses about how components may be
  connected
• possibly generate Grid execution script
