This call will set up all the necessary information for the halo data
|
|
exchanges. In doing so, the library will need to identify the set of
|
|
processes owning the halo indices through the use of the
|
|
<code>desc%fnd_owner()</code> method; the owning processes are the
|
|
topological neighbours of the calling process. If the user has some
|
|
background information on the processes that are neighbours of the
|
|
current one, it is possible to specify explicitly the list of adjacent
|
|
processes with a call to <code>desc%set_p_adjcncy(list)</code>; this will
|
|
speed up the subsequent call to <code>psb_cdasb</code>.
