Package: octave-openmpi-ext Version: 1.0.2-2 Severity: normal Dear Maintainer,
I was running the provided hellocell.m, and hellostruct.m scripts and sometimes it would either run successfully, mpi would error out or it would just crash. command: mpirun -x LD_PRELOAD=libmpi.so.0 -np 4 octave -q --eval hellocell error out ============== ============== warning: X11 DISPLAY environment variable not set warning: X11 DISPLAY environment variable not set warning: X11 DISPLAY environment variable not set warning: X11 DISPLAY environment variable not set warning: dispatch is obsolete and will be removed from a future version of Octave; please use classes instead warning: dispatch is obsolete and will be removed from a future version of Octave; please use classes instead warning: dispatch is obsolete and will be removed from a future version of Octave; please use classes instead warning: dispatch is obsolete and will be removed from a future version of Octave; please use classes instead We are at rank 0 that is master etc..

If you want I can send you the complete output. It would sometimes work, then error, then work, then crash, then work, etc When I did that fixed it was to uninstall the the octave-openmpi-ext package and then use octave to install the 1.1.0 version from sourceforge. While I haven't test it a lot, it seems to work without erring out or crashing, out of the 10 or so times I tested it. If you need any more information please let me know and I'll be happy to provide you anything I can.
