Mark Olesen 9d3427e0b4 ENH: consolidate UPstream::commsStruct code ... - make sizing of commsStruct List demand-driven as well for more robustness, fewer unneeded allocations. - fix potential latent bug with allBelow/allNotBelow for proc 0 (linear communication). ENH: remove unused/unusable UPstream::communicator optional parameter - had constructor option to avoid constructing the MPI backend, but this is not useful and inconsistent with what the reset or destructor expect. STYLE: local use of UPstream::communicator - automatically frees communicator when it leaves scope		2023-04-18 14:08:39 +02:00
