Hi,: 'int' object has no attribute 'send_dict_msg'
I would like to run mpi job from a host machine, as user 'gmaj'. The processes should be executed on the nodes which do not have user 'gmaj'. I would like to use a special user 'mpi' on the nodes. I'm calling mpdboot with rsh set to a script, which simply does ssh as user 'mpi'. This way mpdboot, mpdtrace and mpdringtest work fine, but when I try to use mpiexec it hangs.
Logs on the nodes say:
---
10.0.1.180_man_536 (launch_mpdman_via_fork 3357): invalid username :gmaj: on 10.0.1.180

self.runmainloop()
/opt/intel/impi/4.0.1.007/bin64/mpd.py 3446
mpd.run()
---I've found in sources of mpd.py, that it takes the username from msg['users'], received - I suppose - from mpiexec. When I hardcode 'mpi' username in mpd.py (msg['username'] = 'mpi'), it works fine.
But I haven't found any option in mpiboot or mpiexec to set that. Is there such an option?
Thanks,
Grzegorz Maj

Hi Maj,
It's not the right way of running mpi programs. It's impossible to have such option - if it works on your cluster and doesn't mean that it will work somewhere else.
Regards!
