I'm trying to run this simple code to
***
#include <mpi.h>
int main(){
char port_name[MPI_MAX_PORT_NAME];
int provided;
int thread_level = MPI_THREAD_MULTIPLE;
MPI_Comm inter_comm;
MPI_Init_thread(0, 0, thread_level, &provided);
MPI_Open_port(MPI_INFO_NULL, port_name);
MPI_Comm_accept(port_name, MPI_INFO_NULL, 0, MPI_COMM_SELF, &inter_comm);
// Code never reach here.
MPI_Comm_disconnect(&inter_comm);
MPI_Close_port(port_name);
MPI_Finalize();
return 0;
}
***
The code is run with the following command.
***
> mpic++ server.cc
> mpiexec -mp ./a.out
***
Unfortunately it is crashed immediately after start with the following
error message.
****
$ mpiexec -np 1 ./a.out
[myhost:32527] OPAL ERROR: Timeout in file base/pmix_base_fns.c at line 195

[myhost:32527] *** MPI_ERRORS_ARE_FATAL (processes in this communicator

***
The code works just find on previous versions of open-mpi (1.10.x, 1.8.x)
and (MPICH).
I've compile the open-mpi myself with both default configuration and the
following:
***
> ./configure --enable-mpi-thread-multiple
***
Any suggestion?
