[英]Simple Distributed Graph BGL Example
我正在使用分布式 Boost Graph Library,但沒有成功。 我的目標很簡單:分發由示例中的 BGL 生成器生成的圖。 但是,我有關於bsp_process_group
編譯錯誤:
錯誤列表很大,但基本上說我的typedef
是錯誤的。

這是我非常簡單和錯誤的代碼:
#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;
}
你能發現錯誤嗎? 此外,有什么地方可以找到一些源代碼來閱讀嗎? 我發現的分布式 BGL 文檔非常稀缺......
謝謝!
我相信文檔已經過時了; boost::parallel::bsp_process_group
似乎不再存在。 使用boost::graph::distributed::mpi_process_group
代替(加上添加#include <map>
)允許此代碼在我的機器上編譯(使用 Boost 1.59 的 Ubuntu 15.04)。
