- processor patches use overlapping communication using a different message
tag. This maps straight through into the MPI message tag.
See processorCyclicPolyPatch::tag(). This needs to be calculated the
same on both sides so is calculated as
Pstream::nProcs()*max(myProcNo, neighbProcNo)
+ min(myProcNo, neighbProcNo)
which is
- unique
- commutative
- does not interfere with the default tag (= 1)
- when constructing a GeometricField from a dictionary it will explicitly
