Barrier
event CCL_API barrier (const communicator &comm, const stream &stream, const barrier_attr &attr=default_barrier_attr, const vector_class< event > &deps={})
Barrier synchronization is performed across all ranks of the communicator and it is completed only after all the ranks in the communicator have called it.
Parameters
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
