Ha Chi,
first running MPI applications as root in not a good idea. You must
create users in your rocks cluster without admin rights for all that is
not system management.
Let me know a little more about how you launch this:
1) Do you run "mpirun" from the rocks frontend or from a node ?
2) Ok fro
Dear Patrick,
Thanks so much for your reply,
Yes, we use ssh to log on the node. From the frontend, we can ssh to the
nodes without password.
the mpirun --version in all 3 nodes are identical, openmpi 2.1.1, and same
place when testing with "whereis mpirun"
So is there any problem with mpirun causi
Hi Ha Chi

node with ssh ?
If ssh, can you check that you can ssh from one node to the other
without password ?

mpirun -np 12 --machinefile machinefile.txt --allow-run-as-root ./wrf.exe
But mpirun was unable to access other nodes (as the below photo). But
actually I checked
