@pascalj this is needed to get the executor in mephisto work again:

As a workaround for now, we could introduce dash::global_iterator_traits<GlobIterT>::memory_type, default-defined as void and specialized for ("befriended") global iterators which are actually memory-bound.

Ok, but than why did you removed @pascalj and @rkowalewski? @rkowalewski implemented the memory spaces in DASH and @pascalj implemented the mephisto part. I was only trying to get it to work again.

The changes in this PR are not related to memory spaces or Mephisto but on iterator concepts. Global memory concepts, maybe (both developed and implemented by myself, but why should that be relevant?) I did not remove them from requests for review with malicious intent.
