c++ - 简单的分布式图BGL示例

我正在使用分布式Boost Graph库，但没有成功。我的目标非常简单:分发由BGL生成器from the examples生成的图。但是，我有关于bsp_process_group的编译错误:

错误列表是 HUGE ，但是基本上说我的typedef是错误的。

这是我非常简单且错误的代码:

#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;
}

您能发现错误吗？此外，在某些地方可以找到一些源代码来阅读吗？我发现分布式的BGL文档非常稀少...

谢谢!

最佳答案

我认为文档已经过时了。 boost::parallel::bsp_process_group似乎不再存在。使用boost::graph::distributed::mpi_process_group代替(添加#include <map>)可以使此代码在我的计算机上编译(使用Boost 1.59的Ubuntu 15.04)。
