Hi,
I don't have boost on my Windows, so I made a very similar program just
using MPI, and everything works just fine for me:
D:\work\OpenMPI\tests\CXX>more hello.cpp
# include "mpi.h"
using namespace std;
int main ( int argc, char *argv[] )
{
int rank, size;
MPI::Init ( argc, argv );
size = MPI::COMM_WORLD.Get_size ( );
rank = MPI::COMM_WORLD.Get_rank ( );
printf("Process # %d \n", rank);
MPI::Finalize ( );
return 0;
}
D:\work\OpenMPI\tests\CXX>mpirun -np 3 hello.exe : -np 3 hello.exe
Process # 2
Process # 4
Process # 0
Process # 3
Process # 5
Process # 1
May be something related to boost?
Regards,
Shiqing

Hello,
I have successfully run
mpirun -np 3 .\test.exe
when I try MPMP
mpirun -np 3 .\test.exe : -np 3 .\test2.exe
where test and test2 are identical (just for a trial), I get this error:
[hostname:04960] [[47427,1],0]-[[47427,0],0] mca_oob_tcp_peer_send_blocking: send() failed: Unknown error (10057)

Granted this uses boost::mpi, but it worked for SPMD, and the source for the
main function is trivial:
#include<iostream>
#include<boost/mpi.hpp>
namespace mpi = boost::mpi;
int main(int argc, char* argv[])
{
mpi::environment env(argc, argv);
mpi::communicator world;
std::cout<< "Process #"<< world.rank()<< " says"<< std::endl;
return 0;
}
as far as I understand, there should be 1 world with 6 processes, ranking 0 1 2
, 3 4 5
regards,
