Konsole terminal after upgrade to TW -- mpi warning

English Applications
1

After upgrade to TW, I get an mpi warning below in konsole terminal. It was not there on leap 15.6 prior to upgrade.

(base) tom@mydesktop: ~ $ source .bashrc
Warn: could not determine prefix for system-openmpi
(base) tom@mydesktop: ~ $

mpi-select shows:

(base) tom@mydesktop: ~ $ mpi-selector --list
mpich
mvapich2
openmpi4
openmpi5
(base) tom@mydesktop: ~ $

In bashrc I have had, for a very long time:

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/lib64/mpi/gcc/openmpi/lib64/:/usr/lib64

Is this causing any loss of mpi where needed? Would like to get ride of message.

thanks, tom kosvic

Is this a valid directory?

yes,

(base) tom@mydesktop: ~ $ cd /usr/lib64/mpi/gcc/openmpi/lib64/
(base) tom@mydesktop: /usr/lib64/mpi/gcc/openmpi/lib64 $ l
total 12
drwxr-xr-x 3 root root 4096 Mar 31 06:04 ./
drwxr-xr-x 3 root root 4096 Mar 31 05:20 ../
drwxr-xr-x 2 root root 4096 Mar 31 05:20 openmpi/
(base) tom@mydesktop: /usr/lib64/mpi/gcc/openmpi/lib64 $ l openmpi
total 8
drwxr-xr-x 2 root root 4096 Mar 31 05:20 ./
drwxr-xr-x 3 root root 4096 Mar 31 06:04 ../
(base) tom@mydesktop: /usr/lib64/mpi/gcc/openmpi/lib64 $

Is this wrong directory structure for mpi? If so been wrong for a while

Solved issue of openmpi warning.
openmpi org docs say openmpi needs path to “orterun”.

A locate function found it. I added it to path in .bashrc as below:

export OMPI_HOME=/usr/lib64/mpi/gcc/openmpi4/bin/
export PATH=$OMPI_HOME:$PATH

After sourcing new bash, the warning has gone away. As I said this did not happen in leap 15.6 prior to upgrade to tumbleweed so TW must have some mpi related files in a different location than leap.

Now I will find something to run that will show whether openmpi is actually working. Perhaps an openfoam cfd run.
