send() [1/2]

static void peano4::grid::GridVertex::send ( const peano4::grid::GridVertex & buffer, int destination, int tag, MPI_Comm communicator )

static

In DaStGen (the first version), I had a non-static version of the send as well as the receive.

However, this did not work with newer C++11 versions, as a member function using this as pointer usually doesn't see the vtable while the init sees the object from outside, i.e. including a vtable. So this routine now is basically an alias for a blocking MPI_Send.

send() [2/2]

static void peano4::grid::GridVertex::send ( const peano4::grid::GridVertex & buffer, int destination, int tag, std::function< void()> startCommunicationFunctor, std::function< void()> waitFunctor, MPI_Comm communicator )

static

Alternative to the other send() where I trigger a non-blocking send an then invoke the functor until the corresponding MPI_Test tells me that the message went through.

In systems with heavy MPI usage, this can help to avoid deadlocks.

Datatype

MPI_Datatype peano4::grid::GridVertex::Datatype

staticprivate

Whenever we use LLVM's MPI extension (DaStGe), we rely on lazy initialisation of the datatype.

However, Peano calls init explicitly in most cases. Without the LLVM extension which caches the MPI datatype once constructed, this field stores the type.
