- broadcast : (replaces scatter)
- combineReduce == combineGather + broadcast
- listCombineReduce == listCombineGather + broadcast
- mapCombineReduce == mapCombineGather + broadcast
- allGatherList == gatherList + scatterList
Before settling on a more consistent naming convention,
some intermediate namings were used in OpenFOAM-v2206:
- combineReduce (2206: combineAllGather)
- listCombineReduce (2206: listCombineAllGather)
- mapCombineReduce (2206: mapCombineAllGather)
