UML14 — concurrent vs. parallel ExpansionRegions

  • Key: UML14-412
  • Legacy Issue Number: 6506
  • Status: closed  
  • Source: Daimler AG ( Mario Jeckle)
  • Summary:

    The 3rd rev. draft of UML 2's superstructure document introduces the
    keywords "parallel", "iterative", and "stream" for ExpansionRegions

    But the example figures given at page 296 uses "concurrent" instead of
    "parallel" without any introduction.

    Finally, the metamodel type ExpansionKind (p. 248) solely defines
    "parallel" and the other two keywords mentioned above. "concurrent" is
    completely missing.

    Sure, there is a distinction between concurrency (pseudo-parallel
    execution of processes or threads on one single CPU) and parallelity
    (parallel execution of processes or threads on multiple CPUs) but I'm
    not convinced if we should introduce this distinction at the
    specification level.

    Any ideas?
