Re: [OMPI users] Building Open-MPI with Intel C

Check the output from ldd in a non-interactive login: your LD_LIBRARY_PATH probably doesn't include the location of the Intel runtime. E.g. ssh othernode ldd /path/to/orted Your shell startup files may well differentiate between interactive and non-interactive logins (i.e., it may set PATH

Re: [OMPI users] Building Open-MPI with Intel C

Manually log into one of your nodes. Load the modules you use in a batch job. Run 'ldd' on your executable. Start at the bottom and work upwards... By the way, have you looked at using Easybuild? Would be good to have your input there maybe. On Wed, 7 Apr 2021 at 01:01, Heinz, Michael William vi

Giles, I’ll double check - but the intel runtime is installed on all machines in the fabric. - Michael Heinz michael.william.he...@cornelisnetworks.com On Apr 7, 2021, at 2:42 AM, Gilles Gouaillardet via users mailto:users@lists.open-mpi.o

Re: [OMPI users] Building Open-MPI with Intel C

Michael, orted is able to find its dependencies to the Intel runtime on the host where you sourced the environment. However, it is unlikely able to do it on a remote host For example ssh ... ldd `which opted` will likely fail. An option is to use -rpath (and add the path to the Intel runtime). II

[OMPI users] Building Open-MPI with Intel C

I'm having a heck of a time building OMPI with Intel C. Compilation goes fine, installation goes fine, compiling test apps (the OSU benchmarks) goes fine... but when I go to actually run an MPI app I get: [awbp025:~/work/osu-icc](N/A)$ /usr/mpi/icc/openmpi-icc/bin/mpirun -np 2 -H awbp025,awbp02
