Aha - I see what happened. I have that param set to false in my default mca param file. If I set it to true on the cmd line, then I run without segfaulting. Thanks! Ralph > On Nov 26, 2014, at 5:55 PM, Gilles Gouaillardet > wrote: > > Ralph, > > let me

Ralph, let me correct and enhance my previous statement : - i cannot reproduce your crash in my environment (RHEL6 like vs your RHEL7 like) (i configured with --enable-debug --enable-picky) - i can reproduce the crash with mpirun --mca mpi_param_check false - if you configured with

I will double check this(afk right now) Are you running on a rhel6 like distro with gcc ? Iirc, crash vs mpi error is ruled by --with-param-check or something like this... Cheers, Gilles Ralph Castain さんのメール: >I tried it with both the fortran and c versions - got the same

Re: [OMPI devel] OMPI devel] race condition in abort can cause mpirun v1.8 hang

I tried it with both the fortran and c versions - got the same result. This was indeed with a debug build. I wouldn’t expect a segfault even with an optimized build, though - I would expect an MPI error, yes? > On Nov 26, 2014, at 4:26 PM, Gilles Gouaillardet >

I will have a look Btw, i was running the fortran version, not the c one. Did you confgure with --enable--debug ? The program sends to a rank *not* in the communicator, so this behavior could make some sense on an optimized build. Cheers, Gilles Ralph Castain さんのメール: >Ick -
