[OMPI users] relocating an installation
Is it possible to use the environment or mpirun flags to run an OMPI that's been relocated from where it was configured/installed? (Say you've unpacked a system package that expects to be under /usr and want to run it from home without containers etc.) I thought that was possible, but I haven't found a way that works. Using --prefix doesn't find help files, at least. ___ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users

It should be documented. I'd have expected --prefix to have the same effect, and for there to be an MCA variable. Would there be some problem with either of those? ___ users mailing list users@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/users

Dave, Can you please post the configure command line of the Open MPI you are trying to relocate ?

Re: [OMPI users] relocating an installation
Reuti's right. Sorry about the potentially misleading use of "--prefix" -- we basically inherited that CLI option from a different MPI implementation (i.e., people asked for it). So we were locked into that meaning for the "--prefix" CLI options. > On Apr 9, 2019, at 9:14 AM, Reuti wrote: > >> >> Am 09.04.2019 um 14:52 schrieb Dave Love : >> >> Reuti writes: >> >>> export OPAL_PREFIX= >>> >>> to point it to the new location of installation before you start `mpiexec`. >> >> Thanks; that's now familiar, and I don't know how I missed it with >> strings. >> >> It should be documented. > > There is this FAQ entry: > > https://www.open-mpi.org/faq/?category=building#installdirs > > -- Reuti > > >> I'd have expected --prefix to have the same >> effect, and for there to be an MCA variable.
