icetWallTime(3) IceT Reference icetWallTime(3)NAME
icetWallTime -- timer function
Synopsis
#include <IceT.h>
IceTDouble icetWallTime( void )
Description
Retrieves the current time, in seconds. The returned values of icetWallTime are only valid in relation to each other. That is, the time may
or may not have anything to do with the current date or time. However, the difference of values between two calls to icetWallTime is the
elapsed time in seconds between the two calls. Thus, icetWallTime is handy for determining the running time of various subprocesses.
icetWallTime is used internally for determining the values for the state variables ICET_BUFFER_READ_TIME, ICET_BUFFER_WRITE_TIME, ICET_COL-
LECT_TIME, ICET_COMPARE_TIME, ICET_COMPOSITE_TIME, ICET_COMPRESS_TIME, ICET_RENDER_TIME, and ICET_TOTAL_DRAW_TIME.
Return Value
The current time, in seconds.
Errors
None.
Warnings
None.
Bugs
None known.

icetDataReplicationGroupColor(3) IceT Reference 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 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.
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.
