Do you see the output from the 2 `hostname` commands when this runs? Or does it just hang with no output? > Here's some terminal output, including running the command above with --mca > plm_base_verbose 100 set: > > user@b09-30:~$ sudo ufw status > Status: inactive > user@b09-30:~$ cat .bashrc > export > PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin > export LD_LIBRARY_PATH=/usr/local/lib > user@b09-30:~$ ssh b09-32 hostname > b09-32 > user@b09-30:~$ mpirun --host b09-30 hostname > b09-30 > user@b09-30:~$ mpirun --host b09-30,b09-32 --mca plm_base_verbose 100 hostname I'm interested to see if you get the output from "hostname" when you don't use `--mca plm_base_verbose 100`. Also, when this hangs, what is left running on b09-30 and b09-32? Is it just mpirun? Or are there any orted processes, too? -- Jeff Squyres jsquy...@cisco.com _______________________________________________ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users
