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)
[hostname:04960] [[47427,1],0] routed:binomial: Connection to lifeline
[[47427,0],0] lost
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,
