Gilles raises a good point: if you think you're using Open MPI v5.0.x, but you're somehow not finding a library that is from a prior version of Open MPI, then you may be inadvertently mixing using multiple different versions of Open MPI.
Make sure that your environment (e.g., your PATH and LD_LIBRARY_PATH) are uniformly set to all use the exact same version (and same installation, if possible) of Open MPI. ________________________________ From: [email protected] <[email protected]> on behalf of [email protected] <[email protected]> Sent: Wednesday, April 9, 2025 8:40 PM To: [email protected] <[email protected]> Subject: Re: [OMPI users] OpenMPI-5.0.7 libopen-rte.so.0 missing Natasha, Since Open MPI 5, the previous ORTE runtime has been replaced with PRRTE https://github.com/openpmix/prrte Consequently, there is no more libopen-rte.so Cheers, Gilles On 2025/04/10 07:04 Natasha Evans <[email protected]> wrote: Hi, I'm running a program that uses OpenMPI and I keep getting this error: "error while loading shared libraries: libopen-rte.so.0: cannot open shared object file: no such file or directory" Does anybody know if this error is due to improper installation of OpenMPI or does libopen-rte.so.0 not exist in the newer OpenMPI versions? I'm currently using OpenMPI version 5.0.7 Thanks! To unsubscribe from this group and stop receiving emails from it, send an email to [email protected]<mailto:[email protected]> .
