I had archlinux and openmpi 5.0.1 installed. After updating the prrte package it started to happen. The issue went away after I installed everything from scratch.

Can you provide more information about your setup, how you built and installed Open MPI, ... etc.? In general, the error message is the standard Linux error message when a symbol is unable to be found at run time. In particular, mpirun launches a process called prterun, of which, one of its dependencies (libprte.so.3) is unable to find a symbol named `PMIx_Session_control`. It's likely that it is finding the "wrong" libpmix.so at runtime somehow (i.e., one that does not have that symbol). ________________________________ From: users <[email protected]<mailto:[email protected]>> on behalf of Kook Jin Noh via users <[email protected]<mailto:[email protected]>> Sent: Tuesday, August 13, 2024 10:56 PM To: Open MPI Users <[email protected]<mailto:[email protected]>> Cc: Kook Jin Noh <[email protected]<mailto:[email protected]>> Subject: [OMPI users] prterun: symbol lookup error: /usr/lib/libprrte.so.3: undefined symbol: PMIx_Session_control [vorlket@server openmpi-ucx]$ mpirun -host server:2,midiserver:2 -np 4 /home/vorlket/sharedfolder/mpi-prime prterun: symbol lookup error: /usr/lib/libprrte.so.3: undefined symbol: PMIx_Session_control What's going on?
