Detailed Description

template<class Op, typename Type>
struct ippl::mpi::getNontrivialMpiOpImpl< Op, Type >

Helper struct to look up and store MPI_Op types for custom types and custom operations.

Template Parameters

Op	Operation type, for examples std::plus<Vector<double, 3>>, std::multiplies<...> etc.
Type	The underlying datatype, such as Vector<double, 3>, Matrix<...> etc.

Member Function Documentation

operator()()

template<class Op , typename Type >

MPI_Op ippl::mpi::getNontrivialMpiOpImpl< Op, Type >::operator() ( )

inline

Get the MPI_Op for this CppOp + Type combo.

Returns

MPI_Op

Construct a new lambda object without captures, therefore convertible to a function pointer

Parameters

inputBuffer	pointing to a Type object
outputBuffer	pointing to a Type object
len	Amount of Type objects! NOT amount of bytes!
