Broadcast
event CCL_API broadcast (void *buf, size_t count, datatype dtype, int root, const communicator &comm, const stream &stream, const broadcast_attr &attr=default_broadcast_attr, const vector_class< event > &deps={})
Broadcast is a collective communication operation that broadcasts data from one rank of communicator (denoted as root) to all other ranks.
Parameters
buf – [in,out] the buffer with count elements of dtype serves as send buffer for root and as receive buffer for other ranks
count – the number of elements of type dtype in buf
dtype – the datatype of elements in buf
root – the rank that broadcasts buf
comm – the communicator for which the operation will be performed
stream – a stream associated with the operation
attr – optional attributes to customize operation
deps – an optional vector of the events that the operation should depend on
Returns
ccl::event an object to track the progress of the operation
