Hello all, Thank you all for the suggestions. Takahiro suggestion has gotten me to a point were all of the test will run but as soon as it gets to the clean up step IMB will seg fault again. I opened an issues on IMB's Github but I guess I am not gonna be able to get much help from them. So I will have to wait and see what happens next.
Thanks again for all your help, Adam LeBlanc On Thu, Feb 21, 2019 at 7:22 AM Peter Kjellström <c...@nsc.liu.se> wrote: > On Wed, 20 Feb 2019 10:46:10 -0500 > Adam LeBlanc <alebl...@iol.unh.edu> wrote: > > > Hello, > > > > When I do a run with OpenMPI v4.0.0 on Infiniband with this command: > > mpirun --mca btl_openib_warn_no_device_params_found 0 --map-by node > > --mca orte_base_help_aggregate 0 --mca btl openib,vader,self --mca > > pml ob1 --mca btl_openib_allow_ib 1 -np 6 > > -hostfile /home/aleblanc/ib-mpi-hosts IMB-MPI1 > > > > I get this error: > ... > > # Benchmarking Reduce_scatter > ... > > 2097152 20 8738.08 9340.50 9147.89 > > [pandora:04500] *** Process received signal *** > > [pandora:04500] Signal: Segmentation fault (11) > > This is very likely a bug in IMB not in OpenMPI.
