Detailed Description

template<typename T1, typename T2>
class Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >

This class implements Utilities::MPI::ConsensusAlgorithms::Process, using user-provided function wrappers. The advantage of this class is that users do not have to write their own implementation but can register lambda functions directly.

Member Function Documentation

◆ compute_targets()

template<typename T1 , typename T2 >
std::vector< unsigned int > Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >::compute_targets
overridevirtual

Returns
A vector of ranks this process wants to send a request to.
Note
This is the only method which has to be implemented since the payloads of the messages are optional.

Implements Utilities::MPI::ConsensusAlgorithms::Process< T1, T2 >.

Definition at line 625 of file mpi_consensus_algorithms.h.

◆ create_request()

template<typename T1 , typename T2 >
void Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >::create_request ( const unsigned int  other_rank,
std::vector< T1 > &  send_buffer 
)
overridevirtual

Add to the request to the process with the specified rank a payload.

Parameters
[in]other_rankrank of the process
[out]send_bufferdata to be sent part of the request (optional)
Note
The buffer is empty. Before using it, you have to set its size.

Reimplemented from Utilities::MPI::ConsensusAlgorithms::Process< T1, T2 >.

Definition at line 634 of file mpi_consensus_algorithms.h.

◆ answer_request()

template<typename T1 , typename T2 >
void Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >::answer_request ( const unsigned int  other_rank,
const std::vector< T1 > &  buffer_recv,
std::vector< T2 > &  request_buffer 
)
overridevirtual

Prepare the buffer where the payload of the answer of the request to the process with the specified rank is saved in.

Parameters
[in]other_rankrank of the process
[in]buffer_recvreceived payload (optional)
[out]request_bufferpayload to be sent as part of the request (optional)
Note
The request_buffer is empty. Before using it, you have to set its size.

Reimplemented from Utilities::MPI::ConsensusAlgorithms::Process< T1, T2 >.

Definition at line 644 of file mpi_consensus_algorithms.h.

◆ prepare_buffer_for_answer()

template<typename T1 , typename T2 >
void Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >::prepare_buffer_for_answer ( const unsigned int  other_rank,
std::vector< T2 > &  recv_buffer 
)
overridevirtual

Prepare the buffer where the payload of the answer of the request to the process with the specified rank is saved in. The most obvious task is to resize the buffer, since it is empty when the function is called.

Parameters
[in]other_rankrank of the process
[out]recv_bufferdata to be sent part of the request (optional)

Reimplemented from Utilities::MPI::ConsensusAlgorithms::Process< T1, T2 >.

Definition at line 656 of file mpi_consensus_algorithms.h.

◆ read_answer()

template<typename T1 , typename T2 >
void Utilities::MPI::ConsensusAlgorithms::AnonymousProcess< T1, T2 >::read_answer ( const unsigned int  other_rank,
const std::vector< T2 > &  recv_buffer 
)
overridevirtual

Process the payload of the answer of the request to the process with the specified rank.

Parameters
[in]other_rankrank of the process
[in]recv_bufferdata to be sent part of the request (optional)

Reimplemented from Utilities::MPI::ConsensusAlgorithms::Process< T1, T2 >.
