Description

Redistributions could also support a two-phase-redistribution scheme, that has has two communication steps. This potentially allows for a reduction in the number of messages.

Some thoughts on this:
  • probably only reasonable for in-place redistributions (see #317)
  • the two phase could be detected in xmap-generation or redist-generation step
