Public Member Functions | |
MPITransfer (fhicl::ParameterSet pset, Role role) | |
MPITransfer Constructor. More... | |
virtual | ~MPITransfer () |
MPITransfer Destructor. | |
CopyStatus | copyFragment (Fragment &frag, size_t timeout_usec) override |
Copy a Fragment to the destination. Forces asynchronous send. More... | |
CopyStatus | moveFragment (Fragment &&frag, size_t timeout_usec) override |
Move a Fragment to the destination. More... | |
int | receiveFragment (Fragment &frag, size_t timeout_usec) override |
Receive a Fragment using MPI. More... | |
![]() | |
TransferInterface (const fhicl::ParameterSet &ps, Role role) | |
TransferInterface Constructor. More... | |
TransferInterface (const TransferInterface &)=delete | |
Copy Constructor is deleted. | |
TransferInterface & | operator= (const TransferInterface &)=delete |
Copy Assignment operator is deleted. More... | |
virtual | ~TransferInterface ()=default |
Default virtual Destructor. | |
virtual int | receiveFragment (artdaq::Fragment &fragment, size_t receiveTimeout)=0 |
Receive a Fragment from the transport mechanism. More... | |
virtual CopyStatus | copyFragment (artdaq::Fragment &fragment, size_t send_timeout_usec=std::numeric_limits< size_t >::max())=0 |
Copy a Fragment to the destination. May not necessarily be reliable. More... | |
virtual CopyStatus | moveFragment (artdaq::Fragment &&fragment, size_t send_timeout_usec=std::numeric_limits< size_t >::max())=0 |
Move a Fragment to the destination. This should be reliable, if the underlying transport mechanism supports reliable sending. More... | |
std::string | uniqueLabel () const |
Get the unique label of this TransferInterface instance. More... | |
virtual int | source_rank () const |
Get the source rank for this TransferInterface instance. More... | |
virtual int | destination_rank () const |
Get the destination rank for this TransferInterface instance. More... | |
Additional Inherited Members | |
![]() | |
enum | Role { Role::kSend, Role::kReceive } |
Used to determine if a TransferInterface is a Sender or Receiver. More... | |
enum | CopyStatus { CopyStatus::kSuccess, CopyStatus::kTimeout, CopyStatus::kErrorNotRequiringException } |
Returned from the send functions, this enumeration describes the possible return codes. If an exception occurs, it will be thrown and should be handled normally. More... | |
![]() | |
static const int | RECV_TIMEOUT = 0xfedcba98 |
Value to be returned upon receive timeout. Because receivers otherwise return rank, this is also the limit on the number of ranks that artdaq currently supports. | |
![]() | |
Role | role () const |
Get the TransferInterface::Role of this TransferInterface. More... | |
![]() | |
size_t | buffer_count_ |
The number of Fragment transfers the TransferInterface can handle simultaneously. | |
const size_t | max_fragment_size_words_ |
The maximum size of the transferred Fragment objects, in artdaq::Fragment::RawDataType words. | |

artdaq::MPITransfer::MPITransfer | ( | fhicl::ParameterSet | pset, |
TransferInterface::Role | role | ||
) |
MPITransfer Constructor.
pset | ParameterSet used to configure MPITransfer |
role | Role of this MPITransfer instance (kSend or kReceive) |
* MPITransfer accepts the following Parameters: * "synchronous_sends" (Default: true): When false, use MPI_ISend, otherwise, use MPI_SSend *
MPITransfer also requires all Parameters for configuring a TransferInterface
