Description

From Phil:
Looking at the implementation of our array->group->converse broadcasts, it seems that on systems with meaningful topology (e.g. GNI, PAMI), charm makes no attempt to take that into account. IIRC, this is something Jim had complained about several years ago, that I thought had been addressed.
