Struct Exchanger 

Source 
pub struct Exchanger {}
Expand description

TCP-based all-to-all data exchange between nodes in a network.

Used during setup to exchange RDMA endpoint information (e.g. QueuePairEndpoint) between peers over TCP before RDMA channels are established.

Implementations§

Source§

impl Exchanger

Source

pub fn await_exchange_all<T: Serialize + DeserializeOwned + Clone>( rank: usize, network: &NetworkConfig, data: &T, config: &ExchangeConfig, ) -> Result<Vec<T>, ExchangeError>

Exchanges data with all other nodes in the network, blocking until complete or timeout.

Returns a Vec<T> indexed by rank, where the entry at this node’s rank is a clone of the local data and all other entries come from the corresponding remote nodes.
