Reducing Software Engineering Costs

Efficiency and flexibility are not the only design criteria!

Consider also development costs:

• Avoid extensive code changes

  In a multidimensional grid code, it may be advantageous to avoid partitioning in one dimension, if then existing routines can be reused without change.

• Consider application context
  • Parallel algorithm is part of larger program,
  • Different data structures/decompositions may be required in context,
  • Restructuring of data may be required.
