NAME¶
icetDataReplicationGroupColor -- define data replication.
Synopsis¶
#include <IceT.h>
void icetDataReplicationGroupColor( |
IceTInt |
color ); |
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.
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.
Errors¶
None.
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.
