hello

I am a mew FOAM user. I have a some problem.

This is error message.

I did connect all nodes and shared OpenFOAM-v1912 files.

please help me.

[2phase@knl001 depthCharge3D]$ mpirun -hostfile machines.txt -np 60 -compressibleInterFoam -parallel
----------------------------------------------------------------------------
Open MPI has detected that a parameter given to a command line
option does not match the expected format:

Option: np
Param: -parallel

This is frequently caused by omitting to provide the parameter
to an option that requires one. Please check the command line and try again.

Remove the '-' before 'compressibleInterFoam' ?

Thank you! but, another error message comes out


bash: orted: command not found
--------------------------------------------------------------------------
ORTE was unable to reliably start one or more daemons.
This usually is caused by:

* not finding the required libraries and/or binaries on
one or more nodes. Please check your PATH and LD_LIBRARY_PATH
settings, or configure OMPI with --enable-orterun-prefix-by-default

* lack of authority to execute on one or more specified nodes.
Please verify your allocation and authorities.

* the inability to write startup files into /tmp (--tmpdir/orte_tmpdir_base).
Please check with your sys admin to determine the correct location to use.

* compilation of the orted with dynamic libraries when static are required
(e.g., on Cray). Please check your configure cmd line and consider using
one of the contrib/platform definitions for your system type.

* an inability to create a connection back to mpirun due to a
lack of common network interfaces and/or no route found between
them. Please check network connectivity (including firewalls
and network routing requirements).

From this thread ([OMPI users]) environment variables need to be set in bashrc for non-interactive logins, e.g. at the top of the bashrc file. Do you have this?

Mike also gave helpful troubleshooting tips at this forum post.

thanks.
what means about "non-interactive logins"? I installed OF in shared home.
and I set correct path..

[Светлана]

1. Are all processes expected to run on the same computer or on different ones? If on different ones, the child processes will need to log in to the remote computer without you. This is not interactive.

2. How did you set the path?

Thanks,

Thanks,

I just write these.
export PATH=$PATH:/usr/local/opt/openmpi/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/opt/openmpi/lib

but I installed openmpi-1.10.7 in Thrid party-v1912. so do I write the path differently?

for example,
export PATH=$PATH:/home/2phase/OpenFOAM/ThridParty-v1912/openmpi-1.10.7/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/2phase/OpenFOAM/ThridParty-v1912/openmpi-1.10.7/lib
hanks for your help

[Светлана]

I would suggest to put these two lines at the top (not at the bottom) of your bashrc.

I put two lines at the top in baschrc whicn located in OpenFOAM-v1912/etc.
but the same error message comes out..
thank you

[Светлана]

I would suggest to follow Mike's troubleshooting steps which I linked earlier, and post the results here.
