# icetDataReplicationGroupColor(3)

## 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.
