boost mpi isend tutorial does not work

我運行boost mpi的isend教程。但它給了我以下錯誤。boost mpi isend tutorial does not work

#include <boost/mpi.hpp> 
#include <iostream> 
#include <string> 
#include <boost/serialization/string.hpp> 
namespace mpi = boost::mpi; 

int main(int argc, char* argv[]) 
{ 
    mpi::environment env(argc, argv); 
    mpi::communicator world; 

    if (world.rank() == 0) { 
    mpi::request reqs[2]; 
    std::string msg, out_msg = "Hello"; 
    reqs[0] = world.isend(1, 0, out_msg); 
    reqs[1] = world.irecv(1, 1, msg); 
    mpi::wait_all(reqs, reqs + 2); 
    std::cout << msg << "!" << std::endl; 
    } else { 
    mpi::request reqs[2]; 
    std::string msg, out_msg = "world"; 
    reqs[0] = world.isend(0, 1, out_msg); 
    reqs[1] = world.irecv(0, 0, msg); 
    mpi::wait_all(reqs, reqs + 2); 
    std::cout << msg << ", "; 
    } 

    return 0; 
}

這是MPICH發佈的一個錯誤，告訴您您的程序存在分段錯誤。它可能來自任何事物。通常，這是應用程序的問題，但也可能是您的MPICH/Boost安裝有問題。你有沒有檢查是否有核心轉儲，你可以用來看看事情？ –

在教程中看起來像是一個錯誤。文檔很少，但可能它應該是'mpi :: wait_all（reqs，reqs + 1）;' –

我改變字符串類型爲double或int，它的工作原理。但似乎字符串類型的數據不起作用。購買方式，應該採取Hristo lliev的訴求。
