Questions for the crosscutting Mathematical Methods and 
Computer Science/Infrastructure breakouts.

[These sessions will follow reports from the Applications breakouts.]

(1) List the application areas for which you think that work in your
    crosscutting area could be used to overcome the barriers. For each
    such applications area, provide the following information.
        
        - Characterise the degree of difficulty of providing the 
          needed contributions, from easy (a routine application of
          known technology) to difficult (requires new research ideas).

        - Characterise the cost of providing the required capabilities,
          from inexpensive (software already exists) to expensive (a
          large software development effort would be required).

        - To what extent are there new ideas that have not yet been recognized 
          or used by this application community, but have the potential
          to make a revolutionary change in the way simulation is done
          for this application ?
         
Group the requirements obtained from (1) into one or more related
topics. For each topic, answer the remaining questions.

(2) How would you measure success ? 
        
        - What specific new tools or other qualitative or quantitative 
          increments in capability in this crosscutting area would lead 
          the removal of which specific barriers in the applications areas ?

(3) What are the resources required ?

        - Characterise the current capabilities, in terms of 
          size of software base and level of capability ? How do they
          differ from that which would be required to achieve the goals
          in (1) ?
        
        - What level of effort would be required to move from the
          current capability to the one required to achieve the goals in 
          (1) ? Specify in terms of the number of people, number of
          teams, and skill level.
        
        - How long would it take to develop the new capabilities ?
        
        - What resources and institutional commitments would need to be
          made to support the software investment over its lifetime.
          As a starting point for this exercise, assume a 20-year
          lifetime.
        
        - What is the level of hardware resources required ?
        
        - Who currently funds related activities, and at what level ?

(4) What are the barriers to achieving the goals in (1), in terms of
    requirements this area might have for the other crosscutting areas ? 

        - What are the hardware barriers ?
        - What are the algorithmic barriers ?
        - What are the software barriers ?
