• Data-parallel models (HPF High Performance Fortran).
• Functional models (PACLIB, STURM).
• Semantic gap between source and executed code!
• Small modifications may result in dramatic behavior changes.
• Low-level information of limited value.
  • Source: functional model.
  • Executable: message passing model.
