void Tpetra::Details::Impl::IallreduceCommRequest< PacketType, SendLayoutType, SendDeviceType, RecvLayoutType, RecvDeviceType, 1 >::wait ( )

inlinevirtual

Wait on this communication request to complete.

This is a blocking operation. The user is responsible for avoiding deadlock.

Implements Tpetra::Details::CommRequest.
