I am trying to run the simple hello world code in fortran using Intel MPI library. But all cores have the same rank, as if the program does not run on more than one core. I was following the troubleshooting procedures provided by Intel (Point 2 - https://software.intel.com/en-us/mpi-developer-guide-windows-troubleshoo...), and I got this:
C:\Program Files (x86)\IntelSWTools>mpiexec -ppn 1 -n 2 -hosts node01,node02 hostname
[mpiexec@Sebastian-PC] HYD_sock_connect (..\windows\src\hydra_sock.c:216): getaddrinfo returned error 11001
[mpiexec@Sebastian-PC] HYD_connect_to_service (bstrap\service\service_launch.c:76): unable to connect to service at node01:8680
[mpiexec@Sebastian-PC] HYDI_bstrap_service_launch (bstrap\service\service_launch.c:416): unable to connect to hydra service
[mpiexec@Sebastian-PC] launch_bstrap_proxies (bstrap\src\intel\i_hydra_bstrap.c:525): error launching bstrap proxy
[mpiexec@Sebastian-PC] HYD_bstrap_setup (bstrap\src\intel\i_hydra_bstrap.c:714): unable to launch bstrap proxy
[mpiexec@Sebastian-PC] wmain (mpiexec.c:1919): error setting up the boostrap proxies
Any ideas how to fix it? Any help would be appreciated.
