The C/R Debugging feature (the ability to do reversible debugging or backward stepping with gdb and/or DDT) was added on 8/10/2010 in the commit below: https://svn.open-mpi.org/trac/ompi/changeset/23587
This feature never made it into a release so it was only ever available on the trunk. However, since that time the C/R functionality has fallen into disrepair. It is most likely broken in the trunk today. There is an effort to bring back the checkpoint/restart functionality in the Open MPI trunk. Once that is stable we might revisit bringing back this feature if there is time and interest. -- Josh On Mon, Jun 30, 2014 at 8:35 AM, Ralph Castain <r...@open-mpi.org> wrote: > I don't recall ever seeing such an option in Open MPI - what makes you > believe it should exist? > > On Jun 29, 2014, at 9:25 PM, Đỗ Mai Anh Tú <anhtuce1...@gmail.com> wrote: > > Hi all, > > I am trying to run the checkpoint/restart enabled debugging code in Open > MPI.
