  36  * \brief
  37  * Tests for general functionality in gmx::LocalAtomSetManager and
  38  * gmx::LocalAtomSet, which is only accesible through the manager.
  39  *
  40  * TODO: add testing for behaviour on multiple ranks once gmx_ga2la_t
  41  * may be set up individually and outside domain decomposition initialisation.
