NAME
       icetDataReplicationGroup -- define data replication.


Synopsis
       #include <IceT.h>

       void icetDataReplicationGroup(   IceTInt           size,
                                        const IceTInt *   processes  );


Description
       IceT  has  the ability to take advantage of geometric data that is replicated among processes. If a group
       of processes share the same geometry data, then IceT will split the region of the display that  the  data
       projects onto among the processes, thereby reducing the total amount of image composition work that needs
       to be done.

       Each group can be declared by calling icetDataReplicationGroup and defining the group of  processes  that
       share  the  geometry  with  the local process. size indicates how many processes belong to the group, and
       processes is an array of ids of processes that belong to the  group.  Each  process  that  belongs  to  a
       particular  group  must  call  icetDataReplicationGroup with the exact same list of processes in the same
       order.

       You can alternately use icetDataReplicationGroupColor to select data replication groups.

       By default, each process belongs to a group of size one containing just the local processes  (i.e.  there
       is no data replication).


Errors
       ICET_INVALID_VALUE
               processes does not contain the local process rank.


Warnings
       None.


Bugs
       IceT  assumes  that  icetDataReplicationGroup  is  called with the exact same parameters on all processes
       belonging  to  a  given  group.   Likewise,  IceT  also  assumes   that   all   processes   have   called
       icetBoundingVertices  or  icetBoundingBox  with the exact same parameters on all processes belonging to a
       given group. These requirements are not strictly enforced, but failing to do so may  cause  some  of  the
       geometry to not be rendered.
