Detailed Description

template<typename keyT, typename hashfunT = Hash<keyT>>
class madness::CloudOwnerPmap< keyT, hashfunT >

Process map for the cloud's batch container.

Routes a record to an explicitly assigned owner, falling back to a hash for any record that was never registered. set_owner is collective, so all ranks agree on routing without further communication. Unlike the default cloud container this map is never reset to local, which is what keeps owner pinning stable.
