The optional keyword {bbox} uses a bounding box to only check atoms
in replicas that overlap with a processor's sub-domain when assigning
atoms to processors, and thus can result in substantial speedups for
calculations using a large number of processors. It does require
temporarily using more memory.
The optional keyword {bbox} uses a bounding box to only check atoms in
replicas that overlap with a processor's sub-domain when assigning
atoms to processors. It typically results in a substantial speedup
when using the replicate command on a large number of processors. It
does require temporary use of more memory, specifically that each
processor can store all atoms in the entire system before it is
replicated.
