[maker-devel] Segmentation fault on exit

[Carson Holt]

The segmentation fault occurs after MAKER is finished, so everything is shutting down and OpenMPI is exiting.  Why MPI can't shut down correctly can be for a number of reasons.

  1.  You can try updating OpenMPi or making sure you use the most up to date version available on your system (not uncommon for clusters to have multiple versions installed).  Note that switching versions will require that you reinstall MAKER since it is compiled against the shared libraries of the version you are using.
  2.  Make sure you are not using a different version of mpiexec than the version of OpenMPi you installed MAKER with (check with 'which mpiexec'). This can happen on systems with multiple versions of MPI installed.
  3.  Segmentation faults can be caused by perl/C bindings when perl is exiting under the control of mpiexec (mpiexec actually affects how C code operates and can lead to some odd behavior when the MPI_Finalize shuts down communication).  You can reinstall any perl modules that are written in C if that is the case. One example is the 'forks' module.  One previous user who had a segfault on exit was able to solve it by downgrading the Proc-ProcessTable module from 0.45 to 0.44.
  4.  Make sure you run this command before starting mpiexec or add it to your bash profile to fix issues with shared libraries on OpenMPI. --> export LD_PRELOAD=/<openmpi_location>/lib/libmpi.so

Fortunately MAKER is already finished, so it won't affect your results, but it is a symptom that there is some incompatibility with a C based library and your MPI installation.

Also the -mca btl ^openib options disables the OpenFabrics libraries used by OpenMPI for infiiband communication since those libraries have a known bug where failures occur whenever programs perform a system calls (I.e. every time you open an external program from within a program).  An example of this would be MAKER calling BLAST or MAKER calling Augustus or SNAP.  All of which immediately cause OpenMPI to blow up if you don't add the flag.

Subject: Segmentation fault on exit

Hello,
I am getting a segmentation fault on exit (below). I have read about something similar to this involving hydra. I do no think that is the situation here. I am running Maker 2.31.6 with openMPI and the -mca btl ^openib option to work around an infiniband installation (even though I have no idea what it does). My understanding is that this error has no effect on output because it happens after maker is finished. Can you confirm this? Any ideas what may be causing it? Thank you in advance

Maker is now finished!!!
