Large statistics of whole tables (i.e. table methods), shall make use of OpenMP for a significant speed-up. Using the same threshold as in the string parser modified by the number of bytes should work.

Analysis:

This should straightforwardly be implemented. We only need to look up, how we can use firstprivate and lastprivate. Can probably be combined with the changes in [#640].

Implementation:

  • Implementation: Implemented as described by the analysis.
  • Revision: [r999]
  • Implementation test: Automatic SW tests ran without deviation

Documentation:

  • ChangesLog updated
  • Code changes commented
  • Documentation articles:
    • corresponding documentation articles updated
    • new documentation articles created
    • not needed
  • Language files:
    • corresponding language files updated
    • not needed

Tests:

Change was added to the automatic SW tests. No deviation detected.
