atlas::mpi::Buffer struct

Buffer<DATA_TYPE,SHAPE>

Class that keeps allocation of a MPI buffer including counts and displacements, but with added index operator[] that returns an array::ArrayView<DATA_TYPE,SHAPE> of the part of the buffer for a processor index.

Base classes

template<typename DATA_TYPE>
struct eckit::mpi::Buffer<DATA_TYPE>
Buffer handles colleciton of vector pieces into a larger vector.

Public types

using value_type = DATA_TYPE
using iterator = std::vector<DATA_TYPE>::iterator

Public functions

auto begin() -> iterator
auto end() -> iterator

Public variables

int cnt
std::vector<int> counts
std::vector<int> displs
std::vector<DATA_TYPE> buffer
