mpirun does not propagate LD_LIBRARY_PATH

[MichaelP1]

Hi,

with MPI 2021.1 I have the problem that mpirun does not propate the LD_LIBRARY_PATH variable. With 2019.6 and 2018.5 I have no problems.

If I use -genv to propagte a variable e.g. called LD_LIBRARY_PATH_1, it works. But LD_LIBRARY_PATH is not available.

I tested on RHEL7 and sles12. Same problem.

Any idea what the problem could be?

Thanks,

Michael

Hi Abhishek,

it did not work with my application, so I tried to make the example as simple as possible:
(Intel MPI environment set, machinefile with host1:1 + host2:1)

to be sure LD_LIBRARY_PATH is set:

> echo $LD_LIBRARY_PATH

/share/its/MPI_INSTALLATION/intel_mpi_2021.1/mpi/2021.1.1/lib/release:/share/its/MPI_INSTALLATION/intel_mpi_2021.1/mpi/2021.1.1/lib

> mpirun -machinefile machinefile -n 2 -genv LD_LIBRARY_PATH=$LD_LIBRARY_PATH env > env.txt

There is no LD_LIBRARY_PATH in env.txt (but of course many other variables)

> mpirun -machinefile machinefile -n 2 -genv LD_LIBRARY_PATH1=$LD_LIBRARY_PATH env > env.txt

Now I find the variable LD_LIBRARY_PATH1 in the env.txt. All other variables seem to work but not LD_LIBRARY_PATH.

If I try setting e.g. LD_LIBRARY_PATH1 before in the shell that works as well and is evn propagated without explicitly naming it with -genv

Does that help? Do you need more information?

Thanks,

Michael
