real.exe, wrf.exe: mpirun didn't work

[yunjisong]

hello friends
i am trying to run real.exe and wrf.exe by using mpirun.
so i make mpi.host file to use slave node and try to run(comment: mpirun -np 16 -machinefile mpi.host ./real.exe).
but it didn't work and show this error message.

so i try to use main node and make new mpi.host file.
and the comment(mpirun -np 2 -machinefile mpi.host ./real.exe) is work!


and wrf.exe also in same error and it work in main node not slave node.
but i have to use slave nodes for wrf.exe because of calculation time.
how can i fix this error and why it happend?

I guess the 'slave node' is not connected/communicated with your main node. Unfortunately I don't have an answer how to fix this issue. I always use 'machinefile' to ensure communication between different processors and it works just fine.
Hope someone in the community knows how to fix the issue. Can you consult your computer manager how to implement 'slave node'?
