Я играю с распределенной библиотекой графов Boost без успеха. Моя цель очень проста: распределить граф, сгенерированный генератором BGL from the examples. Тем не менее, у меня есть ошибки компиляции относительно bsp_process_group
:Простой распределенный график BGL Пример
Список ошибок является ОГРОМНЫЙ, но в основном говорит, что мой typedef
является ошибочным.

Вот мой очень простой и ошибочный код:
#include <iostream>
#include <string>
#include <vector>
#include <boost/mpi.hpp>
#include <boost/graph/use_mpi.hpp>
#include <boost/graph/distributed/mpi_process_group.hpp>
#include <boost/graph/distributed/adjacency_list.hpp>
#include <boost/graph/erdos_renyi_generator.hpp>
#include <boost/random/linear_congruential.hpp>
int main(int argc, const char * argv[])
{
boost::mpi::environment env;
boost::mpi::communicator comm;
typedef boost::adjacency_list<boost::vecS, boost::distributedS<boost::parallel::bsp_process_group, boost::vecS>, boost::directedS> graph;
typedef boost::erdos_renyi_iterator<boost::minstd_rand, graph> generator;
boost::minstd_rand gen;
graph g(generator(gen, 100, 0.05), generator(), 100);
if (comm.rank() == 0)
{
// print all nodes for rank 0 here
}
return 0;
}
Можете ли вы ошибку? Кроме того, есть ли место, где я могу найти исходный код для чтения? Распределенная документация BGL, которую я нахожу, очень скудна ...
Спасибо!
