icetDataReplicationGroup(3) IceT Reference icetDataReplicationGroup(3) 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 geome- try 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.

icetAddTile(3) IceT Reference icetAddTile(3) NAME
icetAddTile -- add a tile to the logical display. Synopsis #include <IceT.h> int icetAddTile( IceTInt x, IceTInt y, IceTSizeType width, IceTSizeType height, int display_rank ); Description Adds a tile to the tiled display. Every process, whether actually displaying a tile or not, must declare the tiles in the display and which processes drive them with icetResetTiles and icetAddTile. Thus, each process calls icetAddTile once for each tile in the display, and all processes must declare them in the same order. The parameters x, y, width, and height define the tile's viewport in the logical global display much in the same way glViewport declares a region in a physical display in OpenGL .IceT places no limits on the extents of the logical global display. That is, there are no limits on the values of x and y. They can extend as far as they want in both the positive and negative directions. IceT will project its images onto the region of the logical global display that just covers all of the tiles. Therefore, shifting all the tiles in the logical global display by the same amount will have no real overall effect. The display_rank parameter identifies the rank of the process that will be displaying the given tile. It is assumed that the output of the rendering window of the given process is projected onto the space in a tiled display given by x, y, width, and height. Each tile must have a valid rank (between 0 and $ICET_NUM_PROCESSES - 1$). Furthermore, no process may be displaying more than one tile. Return Value Returns the index of the tile created or -1 if the tile could not be created. Errors ICET_INVALID_VALUE Raised if display_rank is not a valid process rank, if display_rank is already assigned to another tile, or if width or height is smaller than 1. If this error is raised, nothing is done and -1 is returned. Warnings None. Bugs All processes must specify the same tiles in the same order. IceT will assume this even though it is not explicitly detected or enforced.
