labBroadcast
Send data to all workers or receive data sent to all workers
Syntax
shared_data = labBroadcast(srcWkrIdx,data)
shared_data = labBroadcast(srcWkrIdx)
Arguments
srcWkrIdx The labindex of the worker sending the broadcast.
data The data being broadcast. This argument is required only
for the worker that is broadcasting. The absence of this
argument indicates that a worker is receiving.
shared_data The broadcast data as it is received on all other workers.
Description
shared_data = labBroadcast(srcWkrIdx,data) sends the specified
data to all executing workers. The data is broadcast from the worker with
labindex == srcWkrIdx, and is received by all other workers.
shared_data = labBroadcast(srcWkrIdx) receives on each executing worker the
specified shared_data that was sent from the worker whose labindex is srcWkrIdx.
If labindex is not srcWkrIdx, then you do not include the data argument. This
indicates that the function is to receive data, not broadcast it. The received data,
shared_data, is identical on all workers.
This function blocks execution until the worker’s involvement in the collective broadcast
operation is complete. Because some workers may complete their call to labBroadcast
before others have started, use labBarrier if you need to guarantee that all workers
are at the same point in a program.
