icetDataReplicationGroupColor -- define data replication.
void icetDataReplicationGroupColor( GLint color );
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.
Despite the name of the function, icetDataReplicationGroupColor has
nothing to do the color of the data being replicated. Instead, color is
used to mark the local process as part of a given group. When
icetDataReplicationGroupColor is called, it finds all other processes
that have the same color and builds a group based on this information.
icetDataReplicationGroupColor must be called on every processes before
the function will return.
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
This man page should never be installed. It should just be used to help
make other man pages.
