Description Shane Hart 2013-01-29 01:48:56 UTC

Description of problem:  When running a program with mpirun, or executing ompi_info, or basically anything that causes OpenMPI to dlopen() it's plugins the following is printed to STDERR:

[myhostname:14783] mca: base: component_find: unable to open /usr/lib64/openmpi/lib/openmpi/mca_btl_ofud: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored)
[myhostname:14783] mca: base: component_find: unable to open /usr/lib64/openmpi/lib/openmpi/mca_btl_openib: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored)

Version-Release number of selected component (if applicable):

OpenMPI 1.6.3 (Fedora pacakge 1.6.3-8.fc18).  Package was upgraded recently using FedUP.  Also re-installed using yum reinstall openmpi openmpi-devel.

How reproducible:

Every time for me.

Steps to Reproduce:
1. Run mpirun <executable> or ompi_info.
2. When OpenMPI tries to dlopen() plugins error is printed to screen.
3. mca_btl_ofud.so and mca_btl_openib.so are in /usr/lib64/openmpi/lib/openmpi as expected.
  
Actual results:

[necluster.engr.utk.edu:14783] mca: base: component_find: unable to open /usr/lib64/openmpi/lib/openmpi/mca_btl_ofud: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored)
[necluster.engr.utk.edu:14783] mca: base: component_find: unable to open /usr/lib64/openmpi/lib/openmpi/mca_btl_openib: perhaps a missing symbol, or compiled for a different version of Open MPI? (ignored)


Expected results:

No error printed to STDERR.  Note that the program still seems to run correctly, this appears to be just a cosmetic issue.

Comment 1 Orion Poplawski 2013-01-29 02:23:40 UTC

Due to some improper requires filtering we're not requiring opensm-libs.  If you install that the error should go away.  I'm building a hopefully fixed version now.

Comment 3 Shane Hart 2013-01-29 03:08:48 UTC

Thanks for the extremely quick reply.  Installing opensm-libs does indeed get rid of the problem.
