[Syntax:]
|
||
|
|
|
||
|
|
communicate style :pre
|
||
|
|
|
||
|
|
style = {single} or {multi} :ul
|
||
|
|
|
||
|
|
[Examples:]
|
||
|
|
|
||
|
|
communicate multi :pre
|
||
|
|
|
||
|
|
[Description:]
|
||
|
|
|
||
|
|
This command sets the style of inter-processor communication that
|
||
|
|
occurs each timestep as atom coordinates and other properties are
|
||
|
|
exchanged between neighboring processors.
|
||
|
|
|
||
|
|
The default style is {single} which means each processor acquires
|
||
|
|
information for ghost atoms that are within a single distance from its
|
||
|
|
sub-domain. The distance is the maximum of the neighbor cutoff for
|
||
|
|
all atom type pairs.
|
||
|
|
|
||
|
|
For many systems this is an efficient algorithm, but for systems with
|
||
|
|
widely varying cutoffs for different type pairs, the {multi} style can
|
||
|
|
be faster. In this case, each atom type is assigned its own distance
|
||
|
|
cutoff for communication purposes, and fewer atoms will be
|
||
|
|
communicated. See the "neighbor multi"_neighbor.html command for a
|
||
|
|
neighbor list construction option that may also be beneficial for
|
||
|
|
simulations of this kind.
